The 55UQ75006LF is a 55 inch 4K TV from LG. It was launched in 2022. It features a True 8-bit IPS panel.
The max. resolution it can achieve is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 80 ppi.
Picture Quality
After screen size and resolution, the next most important spec of a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.
This TV doesn't come with a color gamut specification, so we have to take a guess.
As this TV features amassive 55 inch screen, it won't come with a cheap panel, so here we can assume its equivalent sRGB coverage to be 90-100% or above. The color quality on this TV should be Lifelike! Meaning it will produce accurate colors.
Understanding the Color Gamut Specification
Color gamut spec of a TV is a measure of the range of colors that the TV can show.
A display with poor color accuracy will produce undersaturated/washed out colors that will spoil the immersion.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 to name a few.
But you don't need to worry about that, below is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, you should look at the static contrast specification as it influences the picture quality substantially.
The importance of static contrast ratio
The static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (<1000:1) will not produce deep blacks. Apart from this, such TVs are likely to suffer from backlight bleeds such as below:

This will affect your experience, especially in a dark room.
Also note, static contrast ratio and resolution go hand in hand when it comes to details. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus lesser detail overall.
There is no mention of this spec in the TV's official datasheet. So we have to make an assumption again. Most IPS panels come with a static contrast ratio between 700:1 - 1500:1. For a 4K TV, we can assume the ratio would be >= 1200:1.
HDR is also supported on this TV in form of HDR10 Pro and HLG (Hybrid Log Gamma).
Coming to brightness, it can go as bright as 250 nits. The panel of this TV is powered by Direct LED backlight technology.
Gaming Performance
If you are planning to use your TV solely for content consumption, you can ignore these specs. But if you are also planning to use the TV for playing games or use it as a PC monitor, make sure to get a TV that features the lowest input lag and response time.
Sadly, LG did not specify the input lag on this unit. But as this is not a cheap TV from LG, input lag on this TV could be 20ms or below.
What is Input Lag and Why it matters ?
This lag is the latency at which your key-presses/mouse movements changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, look for a TV that comes with an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Now, speaking of ergonomics — a VESA mount with interface size of 300 x 300 mm is provided for wall-mounting. Swivel, Tilt or Pivot features are not supported on this unit.
Vertically, the TV measures 55 inches and horizontally 48.98 inches. It is 3.43 inches thick.
Overall this TV weighs 14.4 kgs (including stand). Without stand, it weighs 14.3 Kgs. So plan your space accordingly.
