A Review of LG’s Ultra-Premium & Affordable 2019 C9 4K HDR OLED (OLED55C9) (OLED65C9) (OLED77C9)
Stephan Jukic – July 19, 2019
The LG C9 OLED is the direct successor to the brand’s 2018 C8 TV and is in most ways very similar to its predecessor but slightly better. In other words, this means that it’s generally an excellent OLED 4K TV and even more importantly, a fantastic 4K HDR TV overall. It’s easy to say this about any 4K TV for the sake of trying to sell it but in the case of LG’s OLEDs, it really does apply by most concrete measures of display performance. Their newer OLEDs are especially powerful televisions and the C9 delivers the best of such specs. These include superbly perfect black levels, OLED-perfect contrast and motion handling that’s far superior to that of virtually any 4K LCD TV of any kind. The LG C9 also delivers excellent color performance.
LG’s 4K OLED TVs used to suffer from problems of brightness compared to their LCD counterparts but even this is no longer the case due to strong improvements in the luminosity of their OLED screens, and the C9 is in fact brighter than most LCD 4K HDR TVs on sale today, with only the priciest LCD models exceeding its peak brightness.
• Incredible motion handling and gaming performance
• Superb color rendering for normal and HDR content
• Excellent viewing angles
• OLED-perfect contrast, dimming and black levels
• Beautifully sharp overall picture quality
• Possible burn-in problem due to OLED pixel display
• Could have been brighter still with some content
• Native Audio could be better
The bottom line for the LG C9 OLED is that it’s generally an incredibly powerful, superb performer. We expected little less from a premium OLED 4K HDR TV. That said, this model doesn’t improve enormously upon what the 2018 LG C8 was capable of despite its considerably higher price Thus, if you just want a great 4K HDR OLED TV, without having the absolute newest technology, there are alternative 2018 options available for lower prices. There are also some superb 2018 and 2019 LCD 4K HDR TVs available but they won’t match the C9’s spectacular dimming precision or perfect black levels.
What We Liked about the LG C9 OLED
LG’s C9, has a great deal to sincerely like about it and unless you’re simply opposed to OLED TVs because of worries about the long-term reliability of their display technologies (mainly burn-in issues that we’ll cover in detail below) this is a downright fantastic 4K HDR television by nearly every measure of performance and design quality. In other words, the list of excellent features is quite large and especially in terms of sheer display performance, though other aspects like connectivity are great as well. We’ll focus on the major buying points of this TV in this section.
Wide Viewing Angles
OLED TVs have what are without a doubt the best viewing angles of any TVs in existence today. Among LCD TVs only televisions with IPS display panels (which are fairly infrequent) and a few of the absolute latest LCD TVs from Sony and Samsung with VA display tech come close to matching the excellent sharpness, color and clarity that any OLED TV can deliver if viewed even from extreme wide angles but none of these alternatives quite match OLED’s perfection in this characteristic, and they certainly don’t match its capacity for maintaining perfect contrast. The reason why is that OLED displays, unlike any LCD TV panel, contain their light source, color filters and everything else right inside the pixels seen on the surface of the screen. The inherent design of this, so close to the TV screen surface, ensures nearly perfect visual integrity from a wide angle under any conditions. The fact that modern OLEDs like the C9 TV also deliver incredibly high display brightness that peaks at nearly 1000 nits makes their viewing angles all the better to behold.
Motion handling and Gaming Excellence
Motion handling, pixel response time and frame rate interpolation in OLED TVs like the C9 tend to be incredibly good. In this very newest of LG’s 4K OLED TVs, these specs have been taken to their best levels yet and are truly incredible in how well they allow content to smoothly move across the screen. The response time of pixels on the C9’s screen is particularly incredible at less than a millisecond and this means incredibly fast, smooth, blur-free rendering of even the fastest motion from content like movies or sportscasts, or any other high resolution content for that matter. The reason for this is, once again, OLED technology itself: Because the light source and color filters for the TV’s pixels are literally right inside them, shifts in color for changes in content can happen much more quickly than they do in an LCD TV with light sources behind the pixels on their displays.
The bottom line: The C9 OLED delivers superb motion handling in pretty much every important regard, and though many premium LCD TVs today have gotten remarkably good at doing the same thing, they don’t quite match OLED, especially on pixel responsiveness.
Local Dimming, contrast & black rendering
Nothing in an OLED TV like the LG C9 television is quite as cool and unique as its capability at delivering contrast, black levels or what in LCD TVs is called local dimming. In this one technology they are simply unbeatable and will remain so until some fundamental technological shift in how LCD TVs are built comes along, and that hasn’t happened yet.
The C9 OLED 4K HDR TV, like all OLED TVs, can create total perfect black levels as needed and can thus match these with essentially infinite contrast as well. The reason why this is the case is that unlike any LCD TV in existence, an OLED like the C9 creates light inside each individual pixel and can shut off or turn on and brighten or dim that light on a per-pixel basis, for each pixe, individually. The technology is that precise.
This means total black levels in fully dark areas of the screen and infinite contrast if needed before blacks and lit scenes. LCD TVs by contrast create light behind their pixels through arrays of light emitting diodes that are individually much larger than the pixels in front of them, thus even if they can shut off some of these diodes (as 4K LCD TVs with local dimming can) some of the light from neighboring lit LEDs still bleeds through the light filters inside the much smaller darkened pixels near them. The very priciest and best LCD TVs have full arrays of hundreds of LEDs behind their screens and can even shut them off individually. This is called local dimming and it can be incredibly good but the size of these local dimming zones is even in the best case always much larger than the size of pixels on an LCD 4K UHD screen. Thus, the precision of the technology never quite matches what OLED can do in the C9 or its cousins.
For this same reason above, what is called local dimming in an LCD TV is more like OLED dimming in an OLED TV and since each pixel creates its own light, the precision of OLED dimming is precise down to the level of a single teeny tiny pixel. Thus, while even the absolute best LCD 4K TV with hundreds of local dimming zones and a full LED array behind its LCD panel can create local dimming down to the level of a couple square inches, an OLED TV can shrink it much, much further. This is what the C9 can do superbly and because its peak brightness inside those self-lighting pixels is so strong, the resulting contrast, black levels and OLED dimming look more impressive than ever before.
Color delivery and performance
In terms of color delivery, the LG C9 is incredible. Its capacity for delivering wide color gamut is among the best we’ve ever seen and the overall color rendering of this TV is deeply, powerfully vibrant. This applies especially to the C9’s rendering of colors during playback of HDR content. This LG model (like all of LG’s OLED 4K HDR TVs) supports both Dolby Vision and HDR10 content and it does so to the absolute max of what’s currently possible with 4K HDR TVs in terms of color rendering. That said, even ordinary non HDR colors in content without high dynamic range mastering in this TV are rendered beautifully as long as the video being played back was originally well mastered. For streaming content from apps like Netflix and so forth or from DVD, Blu-ray and especially 4K Blu-rays discs, the LG C9 will knock your socks off like few 4K TVs can.
Having the ability to render extremely vibrant colors or deliver exceptional, perfect black levels and OLED dimming wouldn’t be nearly as awesome to behold if a TV like the LG C9 OLED couldn’t also enhance these other features with powerful display brightness as needed. Fortunately, this particular OLED TV absolutely can. When LG released its first ever OLED 4K TVs back in 2014, they were as perfect as ever at how they delivered perfect blacks and contrast (the technology is inherent to all OLED TVs) but where they screwed up badly compared to LCD TVs was in their really weak display brightness and especially in their low peak brightness.
overall HDR delivery
The LG C9’s combination of extremely strong peak brightness, full HDR color rendering to an outstanding degree and the perfect black levels that are OLED TVs’ single biggest benefit combine together to make the C9 TV into one incredibly good HDR TV. These days just about every 4K television on sale from cheapest to priciest claims HDR support and though this claim is correct in the absolute sense that all these TVs support at least some modicum of high dynamic range visuals, there absolutely are degrees of quality in different televisions. In the case of LG’s C9, the HDR gets taken very close to the best possible picture quality for HDR that you’ll see these days. Certain Sony, Vizio or Samsung 4K HDR TVs can outshine the C9, literally, by delivering several hundred more nits of display brightness, but they’re not likely to beat it on color delivery and they absolutely can’t match the precision of its black levels or dimming technology, both of which are vital for quality HDR.
Smart TV Platform
Smart TV platform technology these days is much more flexible than it used to be. Thanks to a proliferation of compact external streaming media devices like sticks and set-top boxes that you can hook your 4K TV from any brand up to one of them for an entirely unique smart platform experience with access to all sorts of apps. Thus, even if a particular smart TV interface that’s native to your 4K TV doesn’t appeal to you, you’re not stuck with it. That said, the LG OLED C9 and all of LG’s other 2019 4K TVs all come with an excellent, very user-friendly native platform called WebOS 4.5. It features a fairly strong selection of apps and a Home Dashboard for easy navigation between apps and connected devices, and is capable of connectivity with appliances through an Internet of Things feature.
The smart platform of the C9 can be controlled by the TV’s OneRemote, which is both easy to use and offers extensive voice command capabilities. But, like we said, if some apps are missing from the TV itself and you can’t find a way to download them, buying an external streaming media device from Roku or Amazon will change things up easily and quickly.
Connectivity and Gaming/PC responsiveness
Aside from offering a whole spectrum of impressively powerful display characteristics such as those we’ve described above, the LG C9 also comes with a full range of connectivity options that are as advanced as possible for the UHD TVs of 2019. These include four HDMI ports that all support HDMI 2.1 (which allows for 4K content to play back at a native 120Hz without interpolation) and three USB ports. The USB connections are all of the 2.0 variety but that’s still fine for most uses.
Through these ports, the TV also delivers the extremely important benefit of being a very versatile and extremely responsive gaming display for consoles or PCs. In both cases, this TV simply rocks. The LG OLED C9 delivers an incredibly good response time for console games at all sorts of HDR, color, frame rate and resolution settings (we detail the specifics of these much more further down in this review) and for PC gaming connectivity, this TV supports the vast majority of possible PC resolutions and refresh rates, including support for 1080p, 1440p and 4K content at 120Hz. Gamers will love the C9’s combination of astonishingly good general picture quality and extremely fine responsiveness through its HDMI connectivity ports.
What We Didn’t Like
There really are very few meaningful flaws to LG’s C9 OLED TV. It’s hard to imagine almost any normal buyer being disappointed with such a high-performing device. That said, no 4K TV is perfect and for the sake of completeness, we need to mention a few notable problems that this model might offer.
Display brightness weaknesses
While the LG C9 can max out with some wickedly good HDR brightness by the standards of most 4K TVs, and offers very good SDR brightness (how bright it gets for non-HDR content), many other 4K LCD TVs in the same price range do get much brighter than this model. This has to be mentioned. Yes, the C9 does deliver immeasurably better black levels, dimming precision for dark sections and overall contrast but some of today’s best LCD TVs also do these quite well but with much better luminosity even for non-HDR video and TV content.
Furthermore, like all of LG’s 2019 OLED TVs, this model comes with a new and very aggressive Automatic Brightness Limiter feature that can really screw with how bright some content gets by quickly working to dim it too much, and especially if large areas of the screen get too bright. The effect can get very annoying sometimes, with dimness of bright parts dropping down to less than 200 nits, but it can be shut off though the overall peak brightness of onscreen content when this TV isn’t viewing HDR video sources will decrease. In other words, you’re sort of stuck with some screen brightness issues in the C9 OLED when it’s not playing back HDR video, though they’re far from being major problems.
Like most of today’s 4K TVs, premium or not, the C9 doesn’t offer incredibly good native audio technology. This is to be expected since a TV this sleek and elegant can hardly fit a really robust speaker and woofer combo inside itself but we have to mention the issue for those of you who might be expecting a bit more. For casual TV watching, the C9 delivers perfectly good audio and decent bass but if you want some heavy, deep and vibrant kick, you’ll definitely need to go for an external sound system that hooks up to the C9. The good thing about this TV’s audio however is that it fully supports all of the following audio profiles:
• eARC support
• Dolby Atmos via TrueHD via eARC
• DTS:X via DTS-HD MA via eARC
• 5.1 Dolby Digital via ARC
• 5.1 DTS via ARC
• 5.1 Dolby Digital via Optical
• 5.1 DTS via Optical
Potential burn-in problems
Unlike LCD TV panels, OLED displays have always had a bit of a problem with the possibility of screen “burn-in”. This basically means that certain pixels on the TV’s display which constantly show certain static content can eventually “burn” a shadow of that imagery onto the screen even when other content is being shown. LG has made efforts to address the problem by giving their OLED TVs options for managing burn-in but it is something that can affect your C9 after a year or two. However, and this is a major point to consider, any viewing of normal, varied content on one of LG’s OLED TVs will not create noticeable burn-in under any ordinary viewing circumstances. After thorough reviewer testing of LG OLED TVs from 2017, (that continued right to 2019) it took as many as 9000 non-stop hours of displaying the same specific content graphics (scrolling news feeds on news channels and sports logos on sports channels) 24 hours a day for burn-in to start taking hold. No normal consumer uses their 4K TV this way, and unless you do, your OLED, and the C9 in particular, should be fine for several years.
Value for Price & Bottom Line
Our bottom line opinion of the LG OLED C9 4K HDR TV is that it’s fantastic and very much worth going for if you want the newest in OLED technology and connectivity specs. On the other hand, in terms of display performance, this TV does only a marginally better job than the also superb C8 that is its predecessor from 2018 and which we ranked as the single best 4K TV of last year. Thus, if having HDMI 2.1 ports for improved gaming doesn’t matter to you, it’s possible to save a fair bit of money by buying the still excellent C8 OLED or even an E8 edition from 2018. The C9 does perform a bit better on display and color but the differences are fairly modest, though its motion handling is notably better.

Display Performance Metrics
The metrics that we’re going to cover in the following subsections on display performance are all of the key indicators of quality in a 4K TV like the LG C9. They may vary very slightly from one unit to another but for general purposes, they’re precise and uniform enough to be reliable indicators of quality. Different sizes of TV display can change some of these metrics slightly (for example, larger edge-lit LCD 4K TVs tend to have weaker local dimming and peak brightness) but this applies much less often to OLED TVs since each pixel creates its own brightness. The LG C9 maintains pretty much identical display specs in all of its sizes though some TV models come with specs variations for certain specific sizes.
The following metrics of display performance for contrast, black level, color performance, brightness and motion handling (all of which are the most important aspects of display performance) essentially bear out what we said above about the C9 OLED model: This is one fantastic 4K TV in general and quite possibly the best OLED 4K HDR TV we’ve reviewed to-date The OLEDC9PUA not only performs exceptionally well across the board, it also offers the best levels of display brightness we’ve ever seen in an OLED 4K TV. It even slightly beats Sony’s A8F on this specs, which is an impressive achievement.
All of the specs and metrics we’re about to cover cut right to the measured, concrete root of how well the C9 4K HDR TV works. They don’t take into account and marketing and labeling fluff that manufacturers like to pile up around their 4K TVs for the sake of making them seem more exceptional than they really might be. In other words, here we ignore empty labels, fake color brilliance branding and disingenuous terminology of the kind that you’ll often find on the manufacturers promotional materials. Instead, we measure what the LG OLEDC9 HDR TV can actually deliver in a normal consumer setting with only the kind of calibration that’s built into the TV’s controls applied to it.
Black Level, uniformity, Local Dimming and Contrast:
The specs for black level, black uniformity, local dimming and contrast in a 4K TV are some of its most important metrics for overall picture quality and image rendering. They’re also crucial for how well HDR performs. Because all of these particular specs relate specifically to each other, they’re covered together here.
However, a clarification needs to be made here. Specifically, OLED TVs don’t come with local dimming the way it works in an LCD TV. Unlike LCD TVs, in which local dimming is created by LEDs behind the screen being turned off individually or in clusters, OLED display brightness is created inside each individual pixel on the screen. In 4K TVs, this means that 8.29 million pixels can be made to shine or completely stop emitting light as needed for a virtually perfect control of dimming and brightness. This is essentially called OLED dimming and it far outdoes any local dimming technology in any LCD TV in terms of sheer precision. The LG C9, as an OLED TV obviously comes with OLED dimming and yep, it performs on delivering these key specs admirably with its version of the technology.
Most importantly for OLED technology, because light in pixels can be completely shut off in each pixel, the TV’s maximum black level can be total when needed, with no light at all coming from darkened sections of the screen. A further result of this is perfect infinite contrast ratios. All OLED TVs are capable of the above to pretty much the same degree. However what the LG C9 does is create a perception of even better contrast because its capacity for brightness is quite, as we detail with some numbers in our next section.
Accurately measuring how bright a 4K HDR TV is in ways that are meaningful for every-day consumer home theater use means measuring how luminous the TV can get in both SDR (normal content) mode and how bright it can get when set to view HDR content. The main measurements under each are for peak possible brightness, average general screen brightness and for highest sustained brightness. Peak brightness is the maximum possible spot HDR or SDR luminosity of a complete 4K TV display or differently sized sections of its screen as measured in units of brightness called nits (or cd/m2, which is the same thing). Sustained brightness is the highest possible sustained HDR or SDR brightness that the TV screen can manage across its entire screen or parts of it for a prolonged period of time (a few minutes or more).
Peak brightness is the maximum possible spot HDR or SDR luminosity of a complete 4K TV display or differently sized sections of its screen as measured in units of brightness called nits (or cd/m2, which is the same thing). Sustained brightness is the highest possible sustained HDR or SDR brightness that the TV screen can manage across its entire screen or parts of it for a prolonged period of time (a few minutes or more). In other words, Peak brightness consists of how bright sudden illuminations can become and sustained brightness measures prolonged luminosity in content on the display.
In terms of SDR peak brightness, the LG C9 is not quite as powerful as its predecessor the C8 was. In fact, in some measurements of brightness for non-HDR content, it downright underperforms the C8 by a wide margin. If set to view HDR video sources, the LG C9 definitely excels and it manages to do so to a degree that leaves even a majority of LCD/LED 4K TVs in the dust but even on this spec, the C8 from last year was the notably more luminous OLED TV, in some cases by a very wide margin. That said, the C9 is superb at delivering high HDR brightness. OLED TVs used to be almost universally dimmer than their 4K LCD cousins but LG has been steadily pushing the boundaries of what organic light emitting diodes (OLEDs) can output with remarkable success.
On the other hand, the C9 does come with a fairly new LG technology called ABL (Automatic Backlight Limiter) which can get annoying because it suddenly tries to dim content on the screen when certain bright sections are too large. This feature particularly affects the TV in SDR viewing mode and shutting it off completely doesn’t help much either because it causes the C9 to consistently limit its peak SDR brightness to around 250 nits (cd/m2). On the other hand, when the C9 is being used to view HDR content, setting the TV to “Cinema Mode”, with “OLED Light” set at 100 and “Peak Brightness” set to High will create the maximal peak brightness levels seen under the HDR section below. The numbers below demonstrate what we mean:
LG OLEDC9 SDR Brightness
- Overall SDR peak brightness for normal content: 335 nits
- Peak 2% display area display SDR brightness: 449 nits
- Peak 10% display area SDR brightness: 450 nits
- Peak 100% display area SDR brightness: 160 nits
- Sustained 10% SDR brightness: 435 nits
- Sustained 100% SDR brightness: 157 nits
LG OLEDC9 QLED TV HDR Brightness
- Overall HDR peak brightness for normal content: 731 nits
- Peak 2% display area display HDR brightness: 861 nits
- Peak 10% display area HDR brightness: 855 nits
- Peak 100% display area HDR brightness: 161 nits
- Sustained 10% HDR brightness: 807 nits
- Sustained 100% HDR brightness: 139 nits
LG’s C9 OLED TV offers up some outstanding SDR and HDR color performance. In terms of how well it renders wide color gamut for HDR content, this TV is simply fantastic. In other words, the LG C9 is one stellar 4K OLED TV for sheer color quality, vibrancy and richness. In terms of key metrics for high dynamic range color delivery, this television really does great, with 98.50% DCI-P3 color space delivery and over 62% of the even larger and much more difficult to cover Rec 2020 space being covered, which is quite decent. In terms of 10-bit color support for smooth gradations between 1.07 billion HDR color tones, the C9 does a fantastic job, creating smooth and exquisitely gradated color variations in content that has been formatted for 10-bit color delivery.
Additionally, even at the maximum levels of this TV’s considerably powerful luminosity output, the C9 manages to conserve color quality and vibrancy for dark saturated colors in particular. Many 4K TVs can’t pull this off at high levels of peak brightness. Color reproduction also stays very good during reproduction of low light scenes with lots of shadows. These crucial color specs make a huge difference for HDR and SDR video sources of any kind.
In other words, if you use the C9 to watch Dolby Vision or HDR10-mastered movies and shows what you get on the screen looks downright spectacular. However, even for reproduction of normal SDR TV and movie content, LG’s C9 is very, very good at what it delivers. This TV outputs excellent vibrancy, accuracy and realism for most reasonably well-produced content from cable TV, streaming sources, media players and external devices of any kind. The C9 also upscales non-4K video sources very nicely for a smooth, extra-sharp level of picture quality that’s particularly great when this TV is used to view 1080p or 720p movies and shows from TV, cable, streaming or media device sources.
White balance delta E, color delta E and Gamma in the LG OLEDC9 sit at excellent levels of 0.12, 1.51 and 2.09 respectively after calibration. Furthermore, even right out of the box, they’re all very good with respective levels of 3.46, 2.12, and 2.19. We’ve seen better in some other 4K TVs but these aren’t bad values at all. Color temperature in this OLED TV is also highly impressive, being nearly perfect. Older OLED TVs tended towards cooler, rather distracting temperatures due to the bluish light of their organic light emitting diodes. The C9 however avoids this little defect remarkably well.
Motion Handling & Upscaling:
OLED 4K TVs like the C9 are almost universally powerful performers when it comes to motion handling and to pixel response times for smooth onscreen content movement in particular. This isn’t just because they’re expensive premium TVs, it’s a direct result of the unique way in which their display technology works. Since each pixel contains its own light source and color filters, the shifts between colors in pixels that create the perception of fluid changes in content happen much more quickly than they do in even the best LCD TV (which has to rely on light from LEDs behind the pixel surface). As a result, motion blur on the LG C9 is downright minimal, with a specific response time of between 0.3 and 2 milliseconds. No LCD TV can compare to this though newer 2019 premium LCD/LED models have managed to bring their pixel response times down to great levels of 3 or 4 milliseconds.
The LG C9 also delivers some truly excellent motion interpolation of content at all major typical frame rates (24p movies, 30fps TV content, high frame rate streamed video and games on its native 120Hz display panel. 24p Blu-ray discs, DVDs, cable TV and broadcast TV sources as well as streaming media from both native apps and apps inside external streaming media devices can all be played judder-free if they happen to be 24p formatted. Backlight flicker is also not something you’ll find with LG C9’s display, since as an OLED TV, it has no flickering LED backlights to begin with.
Finally, the LG C9 OLED TV does a very robust job of upscaling entertainment content in all major non-4K resolutions from just about any streaming, disc broadcast or other source. It can sharpen 1080p content from any input with minimal to non-existent artifact creation and it pulls off nearly as high a level of upscaling performance for 720p and even 480p SD content sources from TV broadcasts, DVDs and other media files in devices such as USB-connected hard drives. These qualities will work well as long as the source material has also been mastered well and comes with a decent native resolution of its own. Color and contrast are also conserved well in most high quality media sources.
Input Performance for Gaming and PC:
LG’s 2019 OLED TVs, like the 2017 and the 2018 models before them all offer excellent input lag performance for console gaming and PC use at different resolution, color and HDR settings as well as at different refresh rates. Sony’s OLED TVs underperform slightly in these metrics but the C9 delivers them superbly almost across the board. This combined with its HDR support specs makes this particular LG OLED 4K HDR TV into one fantastic console gaming TV for 4K, HDR and normal 1080p Xbox or PS4 Pro gamers. The following are the specific specs for its gaming performance in different console setups:
- 4k @ 60Hz: 13.9 ms
- 1080p @ 60Hz: 13.1 ms
- 1080p @ 120Hz: 7.3 ms
- 1080p @ 60Hz outside Game Mode: 99.3 ms
- 4k @ 60Hz + HDR: 13.7 ms
- 1440p @ 60Hz: 13.6 ms
- 4k @ 60Hz Outside Game Mode : 52.2 ms
- 4k @ 60Hz @ 4:4:4: 13.5 ms
- 4K @ 120Hz: N/A
- 1440p @ 120Hz: 6.9 ms
- 1080p with FreeSync: N/A
- 4K with interpolation activated: 94.7 ms
The LG C9 offers broad and excellent support for different resolutions, frame rates and color settings when connected to a PC rig as well. The following specs show this clearly:
- 1080p @ 120Hz: 10.3 ms
- 1080p @ 60Hz @ 4:4:4: Yes
- 4k @ 60Hz + 4:4:4: Yes
- 1440p @ 60Hz: Yes
- 4k @ 120Hz : Yes via HDMI 2.1
- 4k @ 60Hz @ 4:4:4: Yes
- 1440p @ 120Hz: Yes
Like all newer 4K HDR TVs of any kind or price, or from any brand, the LG OLED C9 offers up a full package of today’s now standard and essential advanced connectivity specs. For connecting it to pretty much any external media device in the most useful possible ways, no user should have connectivity problems with this model as long as all hardware is in working order. One new twist for the LG C9 that has become common with premium 2019 4K UHD TVs is the inclusion of HDMI 2.1 connectivity. Thus, this TV, comes equipped with the 2.1 version of HDMI in all four of its ports. It also includes 3 USB 2.0 ports and other crucial connectivity slots. Another thing we like about the C9 is that it offers full Dolby Vision support and pass-through. Not all 4K TVs offer this, even in 2019 so far. The following are its ports and their specifications:
- HDMI 2.1/2.0: 4 (HDCP 2.2 & full HDMI 2.0a capacity)
- USB : 3 (USB 2.0 x 3)
- Digital Optical Audio Out : 1
- Analog Audio Out 3.5 mm : 1
- Tuner (Cable/Ant) : 1
- Composite In: 1
- Ethernet : 1
- HDR10 support: Yes
- HDR10+ support: Yes
- Dolby Vision HDR support: Yes
- Hybrid Log Gamma HDR support: Yes
- Dolby Vision HDR: Yes
The LG OLEDC9 HDR TV models also offer audio connectivity in the following types.
- 1 Passthrough ARC Dolby Digital
- 1 Passthrough eARC support
- 1 Passthrough Dolby Atmos via TrueHD via eARC
- DTS:X via DTS-HD MA via eARC
- 1 Passthrough 5.1 Dolby Digital via ARC
