The LG UQ9000 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
The 'V'-shaped feet are wide-set and support the TV well, but you need a large table if you aren't planning to wall-mount the TV. The feet lift the display about 2.5 inches above the table, so some soundbars won't fit under the screen. Different model sizes come with slightly different feet, but the 50, 55, and 65-inch models have the feet you see in the photos. There's also a variant of this TV, known as the LG UQ91 in Europe, which comes with a curved center-mounted stand instead of feet.
Footprint of the 65-inch stand: 46" x 10.7".

Wall Mount VESA 300x300
The back of the TV 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, making it difficult to access if the TV is wall-mounted on a fixed stand. The back of the 43-inch model looks a bit different, with the inputs facing out of the TV's right side.

The LG UQ9000 TV has a decent overall build quality. Most of it is plastic, so it's quite light, and the feet support the TV well, with the TV being quite stable. The back panel has a bit of flex, especially near the inputs, but it isn't an issue. However, there are a few quality control issues, like a gap on the top of the display where the panel meets the border.

Contrast
Native Contrast
Unfortunately, the LG TV 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.

As the TV doesn't have local dimming, its backlight is always on at the same intensity, which leads to a washed-out image in dark scenes. However, it also means that the TV has no blooming around bright highlights and subtitles.

The TV's PQ EOTF tracking is excellent, as most scenes are displayed at the brightness level that the content creator intended, although near-black scenes are a bit too bright due to the TV's low contrast ratio. Content mastered at 600 and 1000 nits hard clips when the TV gets close to its peak brightness, leading to a loss of bright detail. Content mastered at 4000 nits doesn't hard clip as severely as content mastered at 600 and 1000 nits, but the roll-off isn't slow enough to truly preserve bright details.
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 UQ9000 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 after calibration with the following settings:
- Picture Mode: Expert (Dark Space, Night)
- Panel Brightness: Max
- Color Temperature: 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.
