LG’s UM7300 4K HDR LCD TV is one of the brand’s 2019 LCD budget 4K HDR TVs and as such it doesn’t come with many extra features or incredible HDR. That said though, this TV is surprisingly good at how well it performs for most content and its gaming performance is especially outstanding. The UM7300 also has great visual quality in bright rooms. Furthermore, it comes with IPS display technology. This means wide viewing angles but it also comes with a negative tradeoff in terms of weak dark levels and contrast. Overall, the UM7300 is a very decent 4K HDR TV by that standards of televisions with IPS display.

• Great smart TV platform


• Lackluster Black levels and contrast (because of IPS display)
• HDR brightness could be better
• Color performance issues
• Native Audio is really bad

Bottom Line

We like the LG UM7300 TV so long as its major limitations are understood. As a really affordable IPS 4K HDR TV with the essential basics. It’s good. That said, unless you really need the wide viewing angles of an IPS display in your TV, we definitely recommend other TVs more than the UM7300.

What We Liked about the UM7300

Despite its budget price and certain lackluster specs, the UM7300 is actually a surprisingly good 4K UHD TV in many ways. This is all the more surprising considering the historical tendency of LG’s low-range LCD IPS TVs, which has for years been pretty bad, especially with the pseudo-“4K” resolution that many of them offered due to substitution of RGB pixels with white light pixels that acted as filler and reduced image quality drastically. The UM7300 at least doesn’t suffer that particular problem and has some great additional qualities that make it rise above what it could have been. Here they are:

Gaming connectivity & performance

Quite probably the single best aspect of the UM7300 is its superbly good gaming performance. This 4K HDR TV really hammers down the input lag within the scope of what it’s capable of in terms of frame rate and HDR capability. Thus, for gaming via console devices, the UM7300 is a highly responsive UHD 4K TV that makes for a great casual gaming edition at a budget price. Its IPS display also helps with viewability due to its wide display angles. Furthermore, as far as handling connectivity to a PC display goes, the UM7300 also offers great options so long as it’s not expected to exceed 60Hz refresh rates. This means no high frame rate gaming but it also makes the UM7300 better than average as a 4K UHD PC monitor due to its great connectivity port options and overall specs.

Great viewing angles

IPS 4K UHD TVs suffer the problem of weak contrast and less-than-stellar black levels and uniformity but what they do to compensate for these things is offer up some superbly good viewing angles. The only other 4K TV types that also offer excellent viewing angles from watching off to either side from dead center are LG’s much more expensive OLED televisions and Samsung and Sony’s most ultra-premium 2019 4K HDR LCD TVs with their new special VA display systems. The LG UM7300 does the same at a ridiculously low price and is thus a useful 4K TV for people who want to fit as much viewing space as possible into their living room.

Very decent color accuracy

The LG UM7300 doesn’t deliver fantastic HDR color performance because it lacks wide color gamut (WCG) but it does come with 10-bit color for high quality, gradient-free RGB color rendering. Furthermore, and just as importantly, this TV’s regular color delivery for general content viewing is extremely accurate after a bit of calibration in the picture settings once the UM7300 is unpackaged. This color accuracy applies across the board, for both HDR content and regular content with this 4K UHD TV.

Decent peak HDR brightness

There are many ultra HD TVs that are much brighter than the UM7300 but by the standards of ultra-budget 4K TV models from rival brands like TCL, Sony, Samsung and others, this particular edition delivers some very decent peak and sustained luminosity. This it does especially well during playback of HDR content, which slightly beefs up its high dynamic range chops, and even the UM7300’s SDR brightness is at least decent. In dark rooms, the brightness of this 4K TV will be good for most content and it holds its own in brightly lit spaces too.

LG’s superb smart TV platform

One of the best native smart TV platforms available today is the LG WebOS system that’s found in all of LG’s newer smart TVs. The edition that comes packed into the UM7300 is version 4.5 and it’s the best we’ve seen yet. We love it for its responsiveness, extreme user-friendliness and great selection of installed apps. The remote control that comes with this LG TV is also great and comes equipped with voice control, support for Google Assistant and great overall TV content navigation.

What We Didn’t Like

Despite its budget price, budget specs and the problems that IPS display screens always bring to any 4K TV they’re installed in, the UM7300 is surprisingly decent for its overall standing on the market, and would be especially satisfying to someone who hasn’t already been spoiled by higher-end 4K HDR TVs like LG’s OLED editions. After all, this TV can’t be judged by the standards of any premium or mid-range model. That said, by any standard, it definitely has its flaws and a few of them are particularly worth mentioning, as we do below.

Black/contrast levels and lack of local dimming

No IPS TV we’ve ever reviewed has really delivered high quality black levels and this is just an inescapable part of the display technology itself. However, higher quality IPS televisions such as LG’s own SM9000 do manage to make the best of their IPS screens with superior screen design and the further enhancement provided by local dimming technology. The UM7300 doesn’t pull this off. For one thing, it has no local dimming to give its black levels a boost and secondly, this TV just doesn’t really manage much in the way of decent contrast. This becomes particularly notable when it’s being used in a dark room. Par for the course, but worth keeping in mind.

Overall display brightness

In our section on positive aspects of the UM7300 above, we mentioned that this LG television offers up decent HDR brightness across the board. This is true, but for watching ordinary content with its HDR mode turned off, it’s not very bright at all. We’ve seen much worse performance in other budget televisions such as TCL’s 2019 4-Series but the UM7300 is only modestly better. If you want a 4K UHD TV with some very decent luminosity even at a low price, we definitely recommend alternative options from Sony, TCL or even Samsung.

Weak native audio

Even for casual TV watching or handling things like newscasts, which hardly require surround sound and deep bass, the UM7300 just barely delivers decent performance. In other words, its native audio is as basic as it comes for a 4K UHD TV and not much good for useful performance if you want to do anything more than watch newscasts or sitcoms casually. If on the other hand you want to use it for loud action movies or gaming with deep rich audio of the immersive kind then we absolutely recommend hooking up an external speaker system or sound bar of some kind.

Value for Price & Bottom Line

As a very cheap IPS 4K TV from a name brand with all the basic essentials of connectivity and display/smart TV performance, the LG UM7300 isn’t that bad at all, and it really is very cheap by 4K TV standards anyhow. However, unless you need the wide viewing angles of its IPS display, or if you need IPS but don’t mind spending just a bit more, there are more recommendable options available from LG, Sony, TCL and Samsung that we think are better choices.

Display Performance Metrics

In the following sections and subsections, we go over the most essential, important and useful measurements of 4K HDR TV quality as they apply to the LG UM7300 NanoCell TV. These are the specs that matter most for judging how well this TV delivers on quality home theater handling. They cover the key specs of brightness, color, motion handling, and other specs for using this particular UHD TV. They are what matters most for movies, TV shows, broadcast content, gaming and even hookup of the TV as a PC monitor if you prefer. We cut out all the fluff and marketing jargon that doesn’t really explain genuine quality anyhow.

The following are based on metrics from our reviewed unit but their accuracy is exact enough to reflect what they should be like for any normally functioning editions of the LG UM7300. Slight variations for some of the specs in the sections below might be the case from unit to unit and with editions of different sizes.

A Review of the LG UM7300 4K HDR LCD TV (43UM7300, 49UM7300, 55UM7300, 65UM7300)

Black Level, uniformity, Local Dimming and Contrast:

Because the LG UM7300 is an IPS 4K HDR TV, it has a display design in which pixels have much greater horizontal width. On the one hand, this is great because it means much wider quality viewing angles. On the other hand though, IPS (In-plane Switching) TVs bleed a lot of light through their darkened pixels because of their design. This of course means really weak contrast and crappy black levels that both become especially noticeable in a dark room. This is the biggest weakness of the LG UM7300 and for users who care about this more than they do about their 4K TV having great contrast deep black tone capability, it’s going to be a problem.

For the reasons above, the UM7300 thus only manages a very modest maximum contrast ratio of 1,102:1

Furthermore, its overall black uniformity across a fully dark screen and darkest possible black level are both fairly weak. Both of these are unfortunate effects of this TV’s IPS screen because of how light bleeds through the IPS pixel design. As a result, the UM7300’s HDR and SDR video quality is only okay. The tradeoff here is great viewing angles but it’s something to think about. The UM7300 also isn’t helped by its lack of local dimming. This technology -which selectively dims LEDs behind the screen for better dark levels- would have gone a long way towards making an IPS TV like the UM7300 deliver much better picture performance.

For both HDR and SDR brightness, the LG UM7300 is a modestly decent performer: it’s not great and we’ve also seen quite a bit worse. In HDR mode this 4K TV supports HDR10 and its combination of strong color performance and decent brightness makes the quality of said high dynamic range rendering more or less okay, though because there’s no Dolby Vision, this TV can’t delivery dynamic scene-by-scene HDR rendering. For qualities like these, LG’s own SM9000 IPS TV gets much, much brighter even though it costs more. The modest brightness of the UM7300 is also slightly hampered by its weak black levels and contrast, which make its bright highlights stand out less than they could.

LG UM7300 SDR Brightness

  • Overall SDR peak brightness for normal content: 276 nits
  • Peak 2% display area display SDR brightness: 307 nits
  • Peak 10% display area SDR brightness: 306 nits
  • Peak 100% display area SDR brightness: 305 nits
  • Sustained 10% SDR brightness: 308 nits
  • Sustained 100% SDR brightness: 304 nits

LG UM7300 TV HDR Brightness

  • Overall HDR peak brightness for normal content: 344 nits
  • Peak 2% display area display HDR brightness: 358 nits
  • Peak 10% display area HDR brightness: 356 nits
  • Peak 100% display area HDR brightness: 293 nits
  • Sustained 10% HDR brightness: 256 nits
  • Sustained 100% HDR brightness: 289 nits

Color Delivery:

The LG UM7300’s color performance is good but not spectacular. This TV doesn’t offer wide color gamut but it can handle 10-bit color rendering fairly nicely. More importantly though, after a bit of calibration, the UM7300 offers superbly good color accuracy once it’s been calibrated in the picture settings options out of the box. On the other hand, this TVs rendering of vibrant colors during playback of bright scenes and accurate colors during shadowy scenes is definitely weak. Fortunately though, the UM7300 doesn’t output extreme luminosity anyhow, so half of this isn’t a huge problem.

A Review of the LG UM7300 4K HDR LCD TV (43UM7300, 49UM7300, 55UM7300, 65UM7300)

Overall though, the UM7300 will output strong and rich colors that look realistic when it’s used to play both ordinary TV content and vibrant HDR video sources. For users who’ve never before owned an HDR 4K TV, the perceived picture quality won’t look bad at all. The color vibrancy of the UM7300 is spoiled a bit by the weak blacks produced by its IPS display but if you bought it knowing you wanted wide IPS viewing angles, this is a fair tradeoff. Furthermore, because of its IPS display, the UM7300 delivers excellent color saturation even when viewed from way off dead center. Typical LCD TVs with VA display can’t manage this.

Here are the UM7300’s key color delivery specs:

  • Pre-calibration White Balance delta-E: 4.41
  • Pre-calibration Color delta-E: 3.35
  • Pre-calibration Gamma: 2.25
  • Post-calibration White Balance delta-E: 0.25
  • Post-calibration Color delta-E: 1.12
  • Post-calibration Gamma: 2.12
  • Wide Color Gamut: 83.8%

Motion Handling & Upscaling:

The LG UM7300 doesn’t handle motion exceptionally but what it does is pretty good and more than useful enough for most movie, sports or TV watching. Combined with this TV’s excellent gaming chops for low input lag, it works nicely for most uses. We’ve seen much better motion interpolation from a number of other mid-range LCD 4K HDR TVs but this model does a very decent job at motion blur control while also rendering motion interpolation decently up to its maximum native display refresh rate of 60Hz. For starters, its pixel response time is great at 5.1 milliseconds, which measures how quickly pixels change color as content shifts across the screen. This of course means low motion blur for movies, TV viewing or sportscasts.

Secondly, the UM7300 performs well enough at judder control with 24p content, and can handle judder-free content delivery from disc media, broadcast, streaming and HDMI sources without a problem. On the other hand, it doesn’t offer this for movies from external 60Hz devices like cable boxes.

We should also note that the UM7300 doesn’t have any variable refresh rate technology like FreeSync or G-Sync for smoother gaming. In general though, this particular 4K TV delivers very good motion handling.

As far as the essential basic spec of content upscaling goes, like virtually all modern 4K UHD TVs, the UM7300 offers excellent sharpening of any well-mastered content from just about any source. 1080p video sources look wonderfully sharp on this TV and even 720p and 480p video is rendered sharply. This is of course very important simply because most of the content available from any and all sources today isn’t natively 4K ultra HD.

Input Performance for Gaming and PC:

LG’s UM7300 is a superbly good 4K UHD TV for gaming with consoles or via PC connectivity (using the TV as a monitor). Its input lag in game mode for console gaming at different resolutions, frame rates, HDR and color settings is superbly low almost across the board. One flaw is the lack of frame rate smoothing technology like FreeSync or G-Sync but unless you’re very serious about gaming, this isn’t a huge problem. Because the UM7300 lacks a native 120Hz refresh rate on its screen, it can’t deliver gaming refresh rates of more than 60Hz in any resolution, so this is worth remembering. However, for most gamers and especially for users who want to play their console or PC games in 4K, this shouldn’t be a problem.

A Review of the LG UM7300 4K HDR LCD TV (43UM7300, 49UM7300, 55UM7300, 65UM7300)

Here are the UM7300’s important input and PC connectivity specs:

  • 4k @ 60Hz: 11.9 ms
  • 1080p @ 60Hz: 12 ms
  • 1080p @ 120Hz: N/A
  • 1080p @ 60Hz outside Game Mode: 101 ms
  • 4k @ 60Hz + HDR: 11.5 ms
  • 1440p @ 60Hz: 11.4 ms
  • 4k @ 60Hz Outside Game Mode : 112.2 ms
  • 4k @ 60Hz @ 4:4:4: 10.5 ms
  • 4K @ 120Hz: N/A
  • 1440p @ 120Hz: N/A 
  • 1080p with FreeSync: N/A
  • 4K with interpolation activated: 108.7 ms

PC Gaming Input Connectivity

  • 1080p @ 120Hz: No
  • 1080p @ 60Hz @ 4:4:4: Yes
  • 4k @ 60Hz + 4:4:4: Yes
  • 1440p @ 60Hz: Yes
  • 4k @ 120Hz : No
  • 4k @ 60Hz @ 4:4:4: Yes
  • 1440p @ 120Hz: No


All essential, modern connectivity options typically found in 4K TVs are present and working smoothly in the LG UM7300. The only problem is that there are less of them than the number you’d find in most other 4K UHD TVs. Thus, this particular televsion comes with 3 HDMI ports with 4K capability at 60Hz (HDMI 2.0a) and offers 2 USB ports. There’s also full high speed WiFi connectivity and an Ethernet port. It’s only other defect is a lack of HDMI 2.1 but since the UM7300 can’t refresh at 120Hz anyhow, this isn’t yet important for any commercial 4K content anyhow. It won’t be a problem for most users.

A Review of the LG UM7300 4K HDR LCD TV (43UM7300, 49UM7300, 55UM7300, 65UM7300)
