The LG UQ9000, also known as the UQ90, is an entry-level 4k TV released as part of LG's 2022 TV lineup. It's the highest-end budget model, sitting below the LG NANO75 2022 and above the LG UQ8000. There's no direct predecessor to this model, but it's very similar to the 2021 LG UP8000. Compared to LG's higher-end models, it's pretty bare, as it lacks any advanced gaming features and doesn't support Dolby Vision or HDR10+. Even though it's an entry-level model, it still runs the 2022 version of LG's proprietary webOS smart interface, which has a few notable improvements and runs quickly, and it comes with LG's popular Magic Remote.

Our Verdict

6.4 Mixed Usage

The LG UQ90 is a mediocre TV overall. It's best suited for watching shows or movies in a moderately lit room, as it can't handle a lot of glare due to its limited peak brightness. It's sub-par for use in a dark room, as it has a low contrast ratio, mediocre black uniformity, and no local dimming feature. It has low input lag for a responsive gaming experience, but there are no advanced gaming features like variable refresh rate support. Finally, it's good overall for use as a PC monitor, and it can display chroma 4:4:4 properly, but some uniformity issues are distracting when browsing the web.

Pros
  • Image remains accurate at a moderate viewing angle.
  • Great selection of streaming apps.
  • Upscales lower resolution content well.
Cons
  • Low contrast results in grayish blacks in a dark room.
  • Not bright enough to overcome intense glare.
  • Noticeable uniformity issues.
5.8 Movies

The LG UQ90 delivers a sub-par movie-watching experience in a dark room. It has a low contrast ratio and no local dimming feature, so blacks look gray and patchy in a dark room, and there are noticeable uniformity issues in dark scenes. On the other hand, it upscales lower resolution content well, great if you watch movies on DVD, and it can remove judder from any source.

Pros
  • Removes judder from all sources.
  • Upscales lower resolution content well.
Cons
  • Low contrast results in grayish blacks in a dark room.
  • No local dimming.
  • Mediocre black uniformity.
  • Noticeable uniformity issues.
7.5 TV Shows

The LG UQ90 is a good choice for watching TV shows in a moderately lit room. It has a great selection of streaming apps, so you're sure to find your favorite shows, and it upscales lower-resolution content well, which is great if you have collections of TV shows on DVD. It has a decent viewing angle, so the image remains accurate even if you move around. Sadly, it can't get very bright, so even though it has good reflection handling, it can't overcome a lot of glare.

Pros
  • Image remains accurate at a moderate viewing angle.
  • Great selection of streaming apps.
  • Upscales lower resolution content well.
Cons
  • Not bright enough to overcome intense glare.
  • Noticeable uniformity issues.
6.7 Sports

The LG UQ90 is an alright choice for watching sports, especially if you're in a room with some lighting or if you have a wide seating arrangement. It has a decent viewing angle, so the image remains accurate when watching from the sides. It also has good reflection handling, but it isn't very bright, so it can't overcome a lot of glare. Sadly, it has a poor response time, so it's hard to make out fine details in fast action.

Pros
  • Image remains accurate at a moderate viewing angle.
  • Upscales lower resolution content well.
Cons
  • Not bright enough to overcome intense glare.
  • Poor response time results in blurry motion.
  • Noticeable uniformity issues.
6.2 Video Games

The LG UQ90 delivers a mediocre gaming experience. It has superb low input lag, which results in an incredibly responsive gaming experience. Sadly, it has a poor response time, so fast motion is blurry, and it lacks any advanced gaming features like variable refresh rate support. It doesn't look very good in a dark room, as it has a low contrast ratio and mediocre black uniformity, so it's best suited for gaming in a moderately lit living room.

Pros
  • Low input lag.
  • Upscales lower resolution content well.
Cons
  • Low contrast results in grayish blacks in a dark room.
  • Limited gaming features, no variable refresh rate support.
  • Poor response time results in blurry motion.
  • Noticeable uniformity issues.
5.5 HDR Movies

Unfortunately, the LG UQ90 is a disappointing TV for watching movies in HDR in a dark room. Its low contrast ratio and lack of local dimming result in a dull, flat HDR experience, and combined with its low peak brightness in HDR, bright highlights don't stand out at all. It can't display a wide color gamut, either, and it has poor color volume. On the other hand, it can remove judder from any source, and it displays 4k content perfectly.

Pros
  • Removes judder from all sources.
Cons
  • Low contrast results in grayish blacks in a dark room.
  • No local dimming.
  • Disappointing peak brightness in HDR.
  • Can't display a wide color gamut.
  • Mediocre black uniformity.
  • Noticeable uniformity issues.
6.3 HDR Gaming

Due to its mediocre gaming performance and disappointing HDR experience, this isn't a very good choice for gaming in HDR. HDR adds almost nothing, as it has a low contrast ratio, no local dimming, and it can't get very bright, so HDR highlights don't stand out at all. Despite its superb low input lag, it's also limited for gaming, as it has a slow response time and no advanced gaming features like variable refresh rate support.

Pros
  • Low input lag.
Cons
  • Low contrast results in grayish blacks in a dark room.
  • No local dimming.
  • Disappointing peak brightness in HDR.
  • Limited gaming features, no variable refresh rate support.
  • Can't display a wide color gamut.
  • Poor response time results in blurry motion.
  • Noticeable uniformity issues.
7.6 PC Monitor

The LG UQ90 is a good choice for use as a PC monitor, but there are some limitations. It has a good viewing angle, so the sides of the screen remain uniform if you're sitting close to the screen. It also displays chroma 4:4:4 signals properly, which is essential for clear text from a PC. Sadly, it can't handle a lot of glare very well, and it has mediocre uniformity, so you'll see some banding and color variation in areas of uniform color, like the white background of your web browser.

Pros
  • Low input lag.
  • Image remains accurate at a moderate viewing angle.
  • Chroma 4:4:4 is displayed properly.
Cons
  • Low contrast results in grayish blacks in a dark room.
  • Not bright enough to overcome intense glare.
  • Poor response time results in blurry motion.
  • Noticeable uniformity issues.

Test Results

Style
Curved No

The LG UQ90 has a simple design, with thin bezels on three sides. The light gray borders are a bit dated, and it doesn't look as premium as LG's NANO and QNED TV lineups.

Design
Stand

The 'v'-shaped feet are wide-set and support the LG UQ90 well, but you'll need a large table if you aren't planning to wall-mount the TV. The feet lift the display about 2.5" above the table, so most soundbars fit underneath it without blocking the screen. There's also a variant of this TV, known as the LG UQ91 in Europe, which comes with a curved center-mounted stand instead.

Design
Back
Wall Mount VESA 300x300

The back of the LG UQ90 is very plain. There are hooks on the back of the TV to help with cable management. Most of the inputs face to the side, but they're inset into the back of the TV, so they're difficult to access if the TV is wall-mounted on a fixed stand.

Build Quality

The LG UQ90 has decent overall build quality. Most of it is plastic, so it's quite light, and the feet support the TV well and keep it stable. There's a bit of flex on the back panel, especially near the inputs, but it isn't an issue. Also, there are a few quality control issues with our unit, including a gap on the top of the display where the panel meets the border.

Unfortunately, the LG UQ90 has inadequate contrast, so blacks look gray and patchy if you're in a dark room, and dark scenes lack shadow detail. There's also no local dimming feature to improve the appearance of dark scenes.

Note: The 50, 60, and 70-inch variants of this model use a VA panel and have much better contrast, so blacks look darker in a dark room.

The LG UQ90 has just passable brightness in SDR. It's bright enough to overcome a bit of glare, but it isn't recommended for a bright room. On the other hand, there's no variation in brightness with different scenes, which is great.

These measurements are in the 'Expert (Dark Space, Night)' Picture Mode, with Panel Brightness at 'Max' and the Color Temperature set to 'Warm 50'.

If you want the brightest image possible, switching to the 'Vivid' Picture Mode, with Adjust Contrast at 'Max', Auto Dynamic Contrast on 'High' and the Color Temp set to 'Cool 50' results in a noticeably brighter image, reaching a peak of 356 cd/m² with a 10% window.

Unfortunately, the LG UQ90 has disappointing peak brightness in HDR. Combined with its low contrast ratio and lack of a local dimming feature, bright highlights in HDR content don't stand out at all and display at the same luminosity as the rest of the scene. There's no variation in brightness with most scenes, but very small highlights are dimmed considerably. The TV tracks the PQ EOTF accurately, as most scenes display at the brightness level the content creator intended, but near-black scenes are a bit too bright due to the TV's low contrast ratio. There's a smooth roll-off near the TV's peak brightness, so there's no loss of fine details in bright scenes.

These measurements are in the 'Cinema' HDR Picture Mode with Panel Brightness and Contrast at their max settings, with Color Temperature at ' Warm 50' and all other image processing disabled. The 'Vivid' Picture Mode with the 'Cool 50' Color Temperature is a bit brighter, reaching a peak of 372 cd/m² with a 10% window. If you find HDR too dark, setting Auto Dynamic Contrast to 'High' with the Color Tone set to 'Cool 5' increases the brightness of most scenes, as shown in this EOTF, but the overall peak brightness of the display is the same.

The LG UQ90 has mediocre gray uniformity. There are noticeable jailbars across the screen, which is distracting when watching sports or using it as a PC monitor, or any other time you have large areas of uniform color on the screen.

Unfortunately, the LG UQ90 has mediocre black uniformity. The entire screen appears blue due to the low contrast ratio, and near-dark scenes are patchy. There's no local dimming feature to improve this.

Note: The 50, 60, and 70-inch variants of this model use a VA panel and have much better contrast, resulting in better black uniformity.

The LG UQ90 is a decent choice for a wide seating arrangement, as the image remains accurate when viewed at a moderate angle. Beyond about 30°, there's a noticeable decrease in brightness that causes colors to appear washed out.

Note that the 50, 60, and 70-inch variants of this model use a VA panel and have much worse viewing angles. Those sizes look best when viewed directly in front.

The LG UQ90 has good reflection handling. It can handle a bit of glare, but because it has limited peak brightness, it can't overcome intense glare in a bright room. The semi-gloss finish reduces the intensity of direct reflections a bit, and unlike anti-reflective coatings found on high-end TVs, there's no purple tint on the screen.

Out of the box, the LG UQ90 has okay accuracy. The white balance is mediocre, but most colors have great accuracy.

Unfortunately, the LG UQ90 has just an okay color gamut, and it can't display a wide color gamut, so HDR content looks muted. The tone mapping is also very bad with bright scenes, as the TV sacrifices accuracy to push brighter highlights in HDR. In dimmer scenes, the tone mapping is much better:

The LG UQ90 has poor color volume. It's mainly limited by its narrow color gamut in HDR. HDR content looks flat and dull overall, as colors aren't as bright as pure white, and it can't display dark saturated colors well due to the low contrast ratio.

The LG UQ90 has excellent gradient handling. You'll notice some banding in areas of similar color, but it's not too distracting. There's also a Smooth Gradation feature to reduce banding, and it works well with real content. This setting works by averaging out areas of similar color, causing a loss of fine details with high-quality content, so we don't recommend leaving it enabled.

Sadly, the LG UQ90 has a poor response time. Most transitions are slow, resulting in a long blur trail around fast-moving objects. The low-frequency flicker of the backlight also causes a double image to appear, so this isn't ideal for fast-paced action gaming or for sports.

No

Unfortunately, this TV doesn't support any DTS formats, which is disappointing as many Blu-rays use this format for their main audio track. If you're planning on using the TV with a UHD Blu-ray player, you should connect the audio from your player to your home theater system instead of using eARC.

The LG UQ90 has an okay frequency response. Like most TVs, the low-frequency extension (LFE) is very high as it has very little bass, with very little thump or rumble. Above the LFE, the frequency response is well-balanced at moderate listening levels, so dialogue is clear and isn't lost in the background. At max volume, there's a bit more compression, especially in the mid and high treble range.

This TV has decent overall distortion performance. There's relatively little distortion in the mid to treble range, which is where most people are likely to notice it. Even at max volume, there's very little total distortion.

The LG UQ90 runs the 2022 version of LG's webOS proprietary smart interface. The interface is fast and easy to use, and the updated version now supports user profiles, meaning you can customize the home page for different users. LG advertises this as version 22, which is a shift from the previous versioning system. Internally, it appears that LG still uses the old versioning system, as the "TV Information" page reports the webOS TV version as version 7.1.0.

Differences Between Sizes And Variants

We tested the 65" LG UQ90 (65UQ9000PUD), but it's also available in 43 inch, 50 inch, 55 inch, 70 inch, and a 75 inch size. Note that the last three letters in the model number (PUD in this case) vary between retailers and individual regions, but there's no difference in performance. There are some differences in performance between sizes, as the 50 inch and 70 inch models use a different panel type.

Internationally, this model is available as a few different variants. Some regions carry either the LG UQ90009LA or the LG UQ90003LA, which are identical to the unit we've tested. Most major markets in Europe carry the LG UQ91 instead, which performs the same but has a center-mounted curved stand. That model is also available in an 86 inch size, and a few regions have a 60 inch model as well. The 86 inch model has an IPS panel, while the 60 inch model has a VA panel.

Size US Model  Panel Type
43" 43UQ9000PUD IPS
50" 50UQ9000PUD VA
55" 55UQ9000PUD IPS
65" 65UQ9000PUD IPS
70" 70UQ9000PUD VA

If you come across a different type of panel or your LG UQ90 doesn't correspond to our review, let us know, and we'll update the review.

Our unit was manufactured in March 2022, and you can see the label here.

Compared To Other TVs

The LG UQ9000 is an entry-level TV that's outclassed by most of its competition. It's an alright choice for watching TV shows or sports in a moderately lit room, but it looks bad in a dark room. Most competing models with VA panels are far better choices than this TV, even for a bright room.

Samsung AU8000
43" 50" 55" 60" 65" 70" 75" 85"

The Samsung AU8000 is much better than the LG UQ9000. The LG UQ9000 uses an IPS panel, which looks bad in a dark room, and it can't get very bright, so it isn't ideal for a bright room, either. The Samsung, on the other hand, looks much better in a dark room, with deep, uniform blacks, and it can handle a bit more glare than the LG. The only advantage of the LG is if you have a wide seating arrangement, as the image remains accurate to a wider angle, but it still looks worse overall.

LG UP8000
43" 50" 55" 60" 65" 70" 75" 82" 86"

The LG UP8000 is better than the LG UQ9000, but the differences are pretty minor. Motion looks smoother and clearer on the UP8000 thanks to its faster response time, so it's better for gaming or watching sports.

Samsung TU7000
43" 50" 55" 58" 60" 65" 70" 75" 82" 85"

The Samsung TU7000 is better than the LG UQ9000. The Samsung delivers much better picture quality, with a much higher contrast ratio and better black uniformity. The Samsung also has a faster response time, so there's less blur behind fast-moving objects. The only real advantage of the LG is that the image remains accurate at a moderate angle, whereas the Samsung is best enjoyed from directly in front.

LG UP7000
43" 50" 55" 65" 70" 75"

The LG UP7000 and the LG UQ9000 are extremely similar. Both of these TVs are basic entry-level models that have limited features and basic picture quality. The differences between them are very minor overall, but the older UP7000 is a bit better overall, as it has better motion handling.

LG NANO75 2021
43" 50" 55" 65" 70" 75" 86"

The LG NANO75 2021 and the LG UQ9000 are extremely similar overall. Both TVs are entry-level 4k TVs with limited picture quality. The differences between them are very minor, but the older NANO75 2021 has better motion handling overall, so it's a slightly better choice.

Hisense U6G
50" 55" 65" 75"

The Hisense U6G is significantly better than the LG UQ9000. The Hisense delivers much better picture quality, especially for watching movies in a dark room, as it has significantly better contrast and a full-array local dimming feature. The Hisense also has higher peak brightness, so bright highlights in HDR stand out. Even though both models lack any advanced gaming features, the Hisense has a much faster response time, meaning there's less blur behind fast-moving objects.
