LG’s E9 is the brand’s successor to the 2018 E8 and is an excellent 4K OLED TV by any measure. Like pretty much all OLEDs, it delivers incredibly deep, basically perfect black levels and infinite contrast that it can generate with its unique display technology. In dark rooms in particular, this makes watching TV and movies or playing games on the E9 downright outstanding in a way that you wouldn’t quite get from an LCD TV of any kind. Furthermore, like all OLED 4K TVs today, this television also delivers incredibly sharp motion handling that also beats anything an LCD TV can do. Other features of the E9 include superb connectivity specs and great gaming support. On a more negative note, LG’s newest OLED is on the expensive side despite offering minor benefits over the LG C9, and like any OLED, it can possibly suffer display burn-in problems. We’ll cover these details and more in the very detailed review below.

A Review of LG’s Ultra-Premium 4K HDR OLED TV, The E9 (OLED55C9) (OLED65E9)


• Excellent color saturation and accuracy
• Superb motion handling
• Superb OLED black levels, contrast and dimming precision
• Nearly perfect viewing angles due to same display technology
• Upscales content of all types beautifully
• Not too badly priced


• Not quite as luminous for HDR content as we’d hoped (but still very bright)
• Burn-in possibility for OLED display (See below in “What we Don’t Like” section for details)
• Gets stiff competition from its own cousin the LG C9 OLED

Bottom Line

The LG E9 OLED is an outstanding 4K HDR TV by almost any measure and offers high quality across the board: if you want a television with this type of display technology that happens to deliver fantastic movie, sportscast, console or PC gaming support and wonderful new connectivity specs. It also offers some of the best game input lag we’ve ever seen in OLED TV technology. Basically, the E9 is a nearly ideal choice. Its only two serious weaknesses are that it’s not as bright as we would have expected and that its own cousin the much more affordable C9 delivers nearly identical performance, making it a possibly better choice because it costs a lot less.

What We Liked about the E9

There is a ton to like about the OLEDE9 HDR TV. The key features of this model are its fantastic display metrics, excellent, cutting edge connectivity specs and a wonderful responsiveness for console or PC gaming that’s among the best we’ve seen in any 2018 or 2019 4K HDR TVs. These are the main benefits of the LG E9, but there are others too. In this section we cover these and a couple of others that gave us a real appreciation of this particular premium UHD TV.

Superb OLED black levels, contrast and dimming precision

The single most unique and noticeable thing about any OLED TV of any kind is how well it delivers black levels, contrast, local dimming and black uniformity. On these specs, OLED technology is absolutely unbeatable and the E9 2019 edition TV doesn’t disappoint at all. Like all of LG (or any rival’s) OLED 4K TVs from the last several years, the E9 delivers literally perfect black uniformity, has the capacity to deliver perfect black depth and as a result of both, it can create a literally infinite contrast ratio. No LCD TV of any kind can quite match these specs in absolute terms though the best LCD 4K HDR TVs try really hard to do so.

The secret to OLED’s success at being so perfect on these specs lies in the fact that these TVs, unlike LCD editions, create their luminosity right inside each of the individual pixels right under the display surface. The organic light emitting diodes inside each pixel (and in a 4K OLED TV like the E9, there are just over 8.29 million of them) can individually light up or completely deactivate. The result is that black areas in high contrast scenery are totally dark and that local dimming is precise down to the level of individual pixels. This is a feature of all OLED TVs but what makes newer editions like the E9 even more outstanding is that they’re among the brightest OLED TVs we’ve yet seen, causing picture quality to look even better thanks to the blend of high brightness, vibrant bright colors and the same perfect black levels as OLED has always offered.

A Review of LG’s Ultra-Premium 4K HDR OLED TV, The E9 (OLED55C9) (OLED65E9)

LCD TVs by contrast rely on an array of much larger LED backlights behind their display surface combined with light filters inside pixels and local dimming of these LED backlights to create dark scenes, uniform black levels and high contrast but because the LED backlights can never quite completely get as precise as OLED pixels or completely cut out backlight bleed inside pixels, the overall quality of black levels, contrast ratio and black uniformity is never perfect. Some LCD TVs come close with full-array LED backlighting and hundreds of specific dimming zones in which individual LEDs shut off but even this technology can’t match OLED.

Why is all this description so important? Because it’s the single feature that most defines the difference between OLED and any LCD 4K HDR TV, and because black levels, contrast and local dimming are crucial for good picture quality in any TV (and especially in HDR TVs like the E9).

Excellent color saturation and accuracy

To further compound the picture quality of the LG E9’s literally perfect black levels, local dimming and contrast, this TV offers some of the best color saturation, vibrancy and color accuracy we’ve ever seen in an OLED TV so far. The LG E9 is exceptionally good at creating deep rich wide color gamut coverage for HDR video content but it also delivers excellent performance on color in regular non-HDR content through a sort of light upscaling process of just being a great TV at color rendering. Furthermore, because the E9 can create excellent 10-bit color rendering (the capacity to create over 1 billion tones or Red Green and Blue (RGB colors), its color gradation for HDR content is wonderfully smooth. Combines with this model’s superbly rich contrast ratio and fairly decent display brightness, the E9’s color rendering makes this an absolutely outstanding HDR TV.

overall HDR delivery
The combination of perfect black levels, contrast and local dimming, extremely strong HDR and SDR (normal content) color performance, and very decent display brightness in the LG E9 TV combine to together to make for one excellent high dynamic range television for those of you who love HDR content wherever you can find it. What makes this superb performance in the E9 even better is that this particular TV supports a wide range of HDR formats, including HDR10 (the most widely used standard), Dolby Vision (arguably the most vibrant of all HDR standards) and even the more recent HLG broadcast HDR mastering that certain broadcast TV content might offer more often in the near future. What’s more, for the growing range of console and PC games that support HDR color and other effects, the visual specs of the LG E9 are fantastic at delivering the best that these games can offer for their graphics.

All that said, performance on graphic elements for color, contrast and so on isn’t everything, especially for fast-paced content and gaming. Motion handling and connectivity are also important, so how does the LG E9 OLED fare on these? Well..

Superb motion handling

The motion handling of OLED TVs is generally really, really sharp. This works especially in terms of controlling motion blur. The main reason why is because the pixel response time in any OLED television is far faster (10 times faster or more) than it has been in any LCD TV we’ve seen so far. What this fundamentally means is that the E9 OLED will do an outstanding job of crisply following even the most fast-paced movements of your favorite sportscasts, heavy duty action movies, TV shows and of course, games. In addition to its fantastic control of motion blur, this 4K TV also offers up a native 120Hz display panel (that refreshes at 120 frames per second) and the capacity to interpolate all content delivered in slower frame rates really well onto its 120Hz screen.

Motion handling is something that this TV and any other LG OLED television will handle better than nearly and LCD TV you could buy for this simple reason: Their motion blur control is completely unbeatable by any LCD TV, while their motion interpolation handling is at least as good as that of any LCD TV on the market.

Excellent Gaming Connectivity

A Review of LG’s Ultra-Premium 4K HDR OLED TV, The E9 (OLED55E9) (OLED65E9)

Given the LG E9’s fantastically good handling of fast-paced onscreen motion, it’s also very useful that this LG TV has some of the best connectivity and gaming input specs we’ve ever seen in any ultra HD HDR TV. Without a doubt it has the best gaming input specs we’ve ever seen in an OLED TV so far (almost exactly matched by its nearly identical cousin the C9). The E9 not only offers extremely low input lag across a broad spectrum of color, picture, resolution and frame rate settings for console games, it also delivers the above-mentioned superb HDR specs to flow through its HDMI inputs from whatever newest console game you play on it. Nearly the same flexibility applies to this TV when it’s connected to a powerful PC rig with the right kind of gaming GPU. As a final but possibly very useful touch, LG ahs given all of its 2019 OLED TVs HDMI 2.1 in all four ports, allowing for 4K resolution at 120Hz if you can even find a game processing setup that can output frame rates close to that.

Upscaling of non-4K HDR content

A final basic detail of the E9’s display specs that we need to mention is the quality of its content upscaling. Nearly every 4K TV being released by now delivers excellent upscale processing of content with a less-than 4K resolution but the E9 does a particularly exceptional job of this, and the OLED display technology, with its fantastic black levels and local dimming helps in a way that LCD TVs can’t match. Since the vast majority of TV content is delivered to even the newest 4K HDR TVs in 1080p, 720p or 480p resolution, the importance of upscaling technology with the crispest possible edge is definitely important. LG’s E9 OLED delivers this wonderfully.

Smart TV Quality

To finish off our section on all the things we liked about the LG E9, we need to also mention its native smart TV platform. WebOS has always been good since we started reviewing the brand’s 4K TVs in 2014 and the latest version, webOS 4.5 with the ThinkQ engine that’s found in the E9 OLED and other premium LG TVs is better than ever. This smart platform is highly responsive, very fast, user-friendly and comes with a great remote control that delivers full voice control technology. The E9’s smart platform comes with a huge selection of pre-installed home entertainment apps (along with all the essentials like Netflix, Amazon Prime and so forth) and is also compatible with internet-of-things devices from the LG brand in your home.

What We Didn’t Like

Since no 4K HDR TV from any brand we’ve ever reviewed is perfect, we didn’t expect the E9 to be an exception. Despite this TV having many more excellent features and performance benchmarks than flaws, it does come with at least a couple of noteworthy defects though none of them are remotely bad enough to justify a low rating. Instead, it’s single biggest flaw is a price vs. value issue created by one of LG’s own OLED TVs that possibly makes the E9 into a pricey purchasing choice. We’ll cover that first.

Value vs. alternative options

While the performance and design weaknesses of the E9 OLED are pretty minor things, one thing about this TV really bothered us and might make buying it into a poor value choice. Simply this: LG’s own 2019 TV the C9 offers pretty much identical performance (and in a couple things even slightly better performance) while costing a fair bit less than the E9. There, we said it and we can’t help but think most users might just be better off with the other LG TV.

The E9 compares really well to Sony’s A8G and and Sony’s A9G though it costs the same as the latter despite being a nearly identical performer, but when we put the E9 up against the C9, we’re hard pressed to find much that makes this TV, which costs a couple hundred dollars more, look like the much more valuable choice. The E9 also doesn’t offer a 77 inch edition that the C9 does (the E9 tops out at 65 inches) and it gets nearly identical brightness to its cheaper cousin when set to HDR content. It’s also a about the same for gaming and has a bit better audio connectivity. Aside from these things, the E9 delivers nearly the same display specs, and the connectivity and input quality of both TVs is pretty much the same.

In other words, if you want great OLED for movies or games, the E9 is more than anything an excuse to spend a bit more money than you need to because the C9 is the nearly identical alternative at a lower price. The most visible difference between the E9 and the C9 is in their designs, with the E9 being the more elegant-looking TV, so if this is a major issue, then the E9 is indeed the “better” choice.

The burn-in problem of OLED

Burn–in is an issue that’s pretty much unique to OLED TVs but it can affect any model, so this weakness of the E9 isn’t specific to this one TV edition. Basically, with OLED, graphic elements from content that display statically for a long time can create a ghostly outline of themselves on the screen even when other content is being played back later. This is especially likely if the TV is left on for hours a day, every day, playing back the same visuals in the same position, like you’d see with ingrained news or sportscast scrolling feeds. Most home users of the E9 or any OLED TV won’t deal with burn-in for years or possibly ever in the ownership lifetime of their TV but it’s worth mentioning as a possibility.

A Review of LG’s Ultra-Premium 4K HDR OLED TV, The E9 (OLED55E9) (OLED65E9)

LG has built countermeasures into its E9. These include a “Screen Shift” pixel shift setting in the TV menu options which will shift an entire image to one side by a couple pixels and then in another direction very gradually. The movement is nearly invisible and it shrinks the risk of burn-in. Another tool in the E9’s picture menu is the pixel refresh setting that puts all of the TVs pixels through a prolonged refresh cycle to clean them against burn-in. This setting does take a good hour to run but it only needs to be done once a year so it’s not a serious burden. Even if you don’t use any of these special settings, burn-in might never appear on your OLED anyhow unless you’re running it non-stop with static elements.

Audio Quality

To quickly finish up our section on the negative aspects of the LG E9 we also need to mention its audio performance. The native sound system of this TV is not at all bad for casual news or TV viewing but it definitely lacks the very serious robustness that you’d get from a decent external speaker system or sound bar. Bass is a bit weak and at high volumes audio can distort a bit at really upped-up volume. So if you want to use the E9 for really having your favorite 4K HDR movies immerse with their audio as much as this TV can make them do this with their visuals, we’d suggest hooking it up to external speakers or a good sound bar. Decent ones are available for $200 or less in some cases.

Value for Price & Bottom Line

Our bottom line opinion of the LG E9 4K UHD OLED TV is simply the following two things: Among recent 4K HDR OLED TVs, this model is one seriously awesome choice, with lots of display performance quality and fantastic gaming responsiveness combined with excellent cutting edge connectivity. On the other hand, the LG C9 delivers nearly the same performance and the same connectivity specs, so it’s probably the better alternative, and especially if you want a giant 77 inch edition OLED, which doesn’t exist for the E9. The E9 does however have the slightly more elegant physical design.

Display Performance Metrics

The details and technical measurements in the sections and subsections that follow cut through all the noise, marketing lingo (usually from manufacturers) technical abstractions and other confusing information to tell you in easy to understand terms how well and why this TV does at delivering the key specs you actually need for a great picture. This is where we’re going to cover the most important aspects of the E9’s real performance across the following range of display and visual specs.

Most importantly, the visual specs explanations below deliver information on what really matters for a TV in terms of quality and measurable performance. In order to do this, they go into the essentials of TV black levels, contrast, dimming capacity, brightness, color delivery, motion handling and input capabilities. We also do an overview of inputs under the main connectivity section below but first we’ll go into visual specs and then elaborate on how the E9 OLED 4K HDR TV’s display handles rendering of motion for movie, console, and PC gaming content, and how well its inputs respond to the connectivity needs of gaming via console or PC.

A Review of LG’s Ultra-Premium 4K HDR OLED TV, The E9 (OLED55E9) (OLED65E9)

The measurements we’ve conducted in the following sections can get very specific, so they might vary slightly from one unit to another. This however doesn’t mean they’re inaccurate. Despite small variations, they reflect pretty closely on general performance in the E9, and especially because it’s an OLED TV. In LCD TVs, some metrics of picture quality can also vary between different screen sizes. This however isn’t quite as much the case with OLED TVs as it can be with LCD since the extremely precise nature of OLED technology eliminates the variability of luminance and black levels that LCD displays show between different sizes and units of the same TV edition.

Black Level, uniformity, Local Dimming and Contrast:

When it comes to black level, black uniformity, local dimming and contrast, OLED TVs like the E9 deliver their best performance by far, simply because they do it nearly perfectly. This isn’t just hype, but a basic characteristic of the technology. The reason why is that with OLED TV displays, each individual pixel of the millions on the screen can have its own internal light activated or deactivated individually or in groups as needed. And because the organic light emitting diode light source is literally integrated with the onscreen pixels, local dimming works on a pixel-specific level.

Also, since individually internally lit pixels bleed almost no light to neighboring pixels and none at all to darkened pixels even further away, an OLED TV like the E9 can create perfectly infinite contrast and total, perfect black levels. If the screen is fully dimmed, it can also create perfect black uniformity that no LCD TV can match, since there is no backlight glow during dark scenes. Another benefit of the E9’s contrast delivery is that it creates no halo effect at all around lit objects against a dark background on the TV.

A Review of LG’s Ultra-Premium 4K HDR OLED TV, The E9 (OLED55E9) (OLED65E9)

So yeah, OLED TVs completely outdo LCD TVs of any kind on specs for back level, contrast or local dimming, and to further understand why, contrast how OLED works with how LCD TVs with LED backlights work: Unlike OLEDs, LCD TVs create luminosity through a backlight system of dozens to hundreds of arrayed LEDs that are behind the LCD display and its pixels. They create dark/bright areas by a combination of the LEDs being turned off in sections and the display pixels blocking out backlight selectively as needed.

With their LED technology, the best LCD TVs come with full-array LED backlighting and multi-zone local dimming, meaning that they have hundreds of LEDs covering the entire back of their screen and dozens or hundreds of local dimming zones in which some of these LEDs shut off selectively for better black levels. Even in these TVs however, some light always bleeds through along the edges between bright and dark content. Furthermore, even hundreds of LEDs and hundreds of dimming zones are nowhere near as precise as millions of individual pixels in an OLED display doing the same thing. This is what most makes OLED so much cooler in these ways.


When it comes to display metrics, the way by which we assess them in the E9 or any of the other 4K UHD TVs we review are basically as follows: The main metrics to consider are absolute maximum peak brightness and sustained brightness in nits (cd/m2) across areas that cover between 2%, 10% and 100% of the TV screen. We then also measure how much average brightness the LG E9 outputs in general during regular content viewing. These measurements are given for the TV when it’s set to view SDR (normal TV, streaming, disc and broadcast) content) and high dynamic range (HDR) content of the kind that’s now more available for today’s increasingly common HDR TVs like this model.

The OLED E9 compared to Samsung’s Q90R (on the left)

In terms of display brightness, the LG E9 is an outstanding performer compared to most other 2019 OLED TVs. It delivers notably better brightness than both of Sony’s 2019 OLED 4K HDR rival TVs and compared to the more expensive A9G in particular, the E9 is the much better performer at a cheaper price, it also outperforms or matches them on SDR (regular content) brightness rendering. This capacity for high display brightness is in fact one of the things that most sets the E9 apart from LG’S otherwise similar-performing but cheaper C9 edition. The E9 is the much better OLED for high display luminosity.

We were a bit disappointed that neither LG or Sony managed to finally break the 1000 nit mark on their 2019 HDR OLEDs, but at least the E9 stays close to the high levels of peak brightness that we were getting used to from OLED TVs since 2017.

In basic terms, the E9 is one very luminous TV by OLED standards. On absolute maximum peak brightness in HDR mode, this OLED edition performs wonderfully at over 850 nits and when it’s being used in normal HDR content mode, maximum display brightness is downright excellent by OLED standards at just over 448 nits. Average general display brightness of the E9 is also fantastic in HDR mode at 725 nits. In other words, this particular OLED HDR TV is great at all-around brightness while hitting a couple very strong highlights of luminosity when used for regular content.

Below are the E9’s specific measured specs across different settings:

A Review of LG’s Ultra-Premium 4K HDR OLED TV, The E9 (OLED55E9) (OLED65E9)

LG E9 OLED SDR Brightness

  • Overall SDR peak brightness for normal content: 331 nits
  • Peak 2% display area display SDR brightness: 445 nits
  • Peak 10% display area SDR brightness: 443 nits
  • Peak 100% display area SDR brightness: 160 nits
  • Sustained 10% SDR brightness: 428 nits
  • Sustained 100% SDR brightness: 158 nits

LG E9 OLED TV HDR Brightness

  • Overall HDR peak brightness for normal content: 727 nits
  • Peak 2% display area display HDR brightness:851 nits
  • Peak 10% display area HDR brightness: 840 nits
  • Peak 100% display area HDR brightness: 150 nits
  • Sustained 10% HDR brightness: 807 nits
  • Sustained 100% HDR brightness: 139 nits

Color Delivery:

The LG E9 outputs some truly excellent, vibrantly rich color quality pretty much across the board. This applies especially to its rendering of HDR color in the form of Wide Color Gamut coverage, but the TV’s 10-bit color gradation rendering is also superb. In other words, this 4K TV is stunningly vibrant and accurate with its primary color combinations and gradations. Color volume is a bit weak in the E9 under really bright display output but this was the only major flaw we noted as far as color performance goes. The E9 can handle both HDR and SDR color delivery exceptionally well and even helps ordinary non-HDR movies and programming improve color quality, vibrancy and accuracy due to its powerful color specs. In other words, it not only upscales resolution but also picture quality through its HDR capabilities.

In terms of concrete, specific measurements, this 2019 LG OLED renders very good Wide Color Gamut (WCG) at 98.5% of the color space, which is downright great. More negatively though, where this TV also ends up being a bit weak is on playback of very bright content. This is a really minor issue for most content but the E9’s color saturation is only decent with extremely bright scenes because the white subpixels that are responsible for brightness tend to de-saturate the vibrant pure colors that should stand out in onscreen content. This however only really happens when bright highlights in HDR mode are taken to their maximum.

A Review of LG’s Ultra-Premium 4K HDR OLED TV, The E9 (OLED55E9) (OLED65E9)

As for color accuracy in the E9, these are specs that we measure by the key specs of white balance delta E, color delta E and Gamma. With this particular LG TV, these key metrics are decent right out of the box and become excellent after modest color calibration adjustments in the TV’s picture settings.
Pre calibration settings and post calibration settings for these key color accuracy settings are as follows:

LG E9 Pre-calibration color settings

  • White balance delta E: 3.2
  • Color delta E: 2.09
  • Gamma: 2.2

LG E9 post-calibration color settings

    • White balance delta E: 0.43
    • Color delta E: 0.89
    • Gamma: 2.11

Motion Handling & Upscaling:

OLED TVs almost universally beat even the best premium LCD 4K HDR TVs on motion handling for two simple reasons: First of all, they deliver much better motion blur control with a far faster pixel response time and secondly, they deliver equally good or slightly better motion interpolation on their 120Hz displays. Since they outclass LCD TVs by at least 5 to 10x on motion blur and perform just as well on motion interpolation of lower frame rate content or movies from external devices, they beat LCD overall. This is what the LG E9 does superbly.

It is however worth noting that the extremely strong motion blur response time of the E9 can also create stutter in certain types of lower frame rate content. However, in order to counter this, the E9 offers up some excellent motion interpolation settings such as black frame insertion and TruMotion for smoothing out low frame-rate content on its screen. The overall result is that content played back at assorted different frame rates is delivered very little blur, flicker or distortion.

A Review of LG’s Ultra-Premium 4K HDR OLED TV, The E9 (OLED55E9) (OLED65E9)


In more specific terms, the E9 delivers a superbly good, nearly instant pixel response time of just 0.2 milliseconds. Even the best LCD TVs we’ve reviewed manage a pixel response time of no better than 1 or 2 milliseconds by comparision. This is a measurement of how quickly a TVs pixels change color or brightness in response to content changes. The E9 also offers up nearly perfect judder control for extremely clean playback of 24p movie content being supported from any source at all, be it streaming media, HDMI-connected media device or even broadcast and cable TV. The E9’s overall mix of fast pixel response time, great motion interpolation and strong judder control combines to deliver a fantastic capacity handling any favorite sportscasts, movies, streaming TV shows, games and nearly anything else you use this television for.

One thing the LG E9 lacks however are some of the very useful gaming/movie playback technologies that premium ultra HD TVs from rivals like Samsung come with. So in other words, this TV offers no AMD FreeSync or Nvidia G-SYNC for your favorite PC games. What this TV does have though is the new HDMI VRR variable refresh rate technology which is compatible with the Xbox One console. It works similarly to AMD FreeSync and could spread to other gaming consoles sooner or later.

Input Performance for Gaming and PC:

As we’d mentioned in our introductory section on things we liked about the LG E9, this TV delivers some truly outstanding performance when used for gaming with consoles like the Xbox One editions or the PlayStation 4 and its Pro version. We’ve seen better input lag specs from very few other 4K HDR TVs at any price range and even any OLED TVs from last year aren’t as great as the E9. Among 2019 OLED TVs, the E9 completely outclasses Sony’s OLEDs on console and PC connectivity. In essence, for gaming connectivity through consoles, regardless of resolution, HDR, color settings or other settings, this TV really seripusly has things nailed down tightly, as the specs below demonstrate.

A Review of LG’s Ultra-Premium 4K HDR OLED TV, The E9 (OLED55E9) (OLED65E9)

Here are some of the key specific specs for its gaming performance in different console setups:

      • 4k @ 60Hz: 13.5 ms
      • 1080p @ 60Hz: 13.2 ms
      • 1080p @ 120Hz: 7.0 ms
      • 1080p @ 60Hz outside Game Mode: 98 ms
      • 4k @ 60Hz + 10 bit HDR: 13.7 ms
      • 1440p @ 60Hz: 13.4 ms
      • 4k @ 60Hz Outside Game Mode : 48.2 ms
      • 4k @ 60Hz @ 4:4:4: 13.5 ms
      • 4K @ 120Hz: N/A
      • 1440p @ 120Hz: 7.9 ms
      • 1080p with FreeSync: N/A
      • 4K with interpolation activated: 90.7 ms

The LG E9 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:

The premium 2019 4K HDR TV editions of Samsung, LG, Vizio and other brands have started to adopt the new HDMI 2.1 connectivity standard for their TV ports and the E9 does as well. This means the ability to transmit 4K content at more than 60Hz along with a few other useful things. For fans of movie or TV 4K content HDMI 2.1 doesn’t make a huge difference quite yet because no commercial content sources need it to deliver movies and programming anyhow. However, for when HDMI 2.1 starts being relevant, the LG E9 OLED is ready for it with all four of its ports supporting the new HDMI format. This TV also delivers perfectly modern connectivity in the form of HDMI 2.0, USB and other key connections. It’s future-proofed and good enough for just about any content or device you want to hook up to it.
