ABOUT THIS TV

LG 55UQ7570PUJ 400x400 Image LG 55UQ7570PUJ

The 55UQ7570PUJ is a 55 inch 4K TV from LG. It was launched in 2022. It features a True 8-bit IPS panel. It can display a maximum resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 80 ppi.

Picture Quality

After screen size and resolution, the next most important feature to look for in a display is its Color Reproduction, which is defined by its color gamut specification.

This TV doesn't come with a color gamut specification, but don't worry, we have other means to guess that.

Now, since the TV features a 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. Undoubtedly The color quality on this TV should be Lifelike! It will produce accurate colors AS IT IS intended.

Understanding the Color Gamut Specification

Color gamut specification of a display is a measure of the range of colors that the display can show.

In layman terms, it indicates the ability of a TV to produce accurate colors. A display with low gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.

It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 to name a few. It is upto the manufacturer which one they choose.

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.

Color Gamut Chart

After color gamut, you should look at the static contrast specification as it influences the picture quality substantially.

The importance of static contrast ratio

A TV with low static contrast ratio will not produce deep blacks and possibly bleed backlight as shown in the below image:

Backlight bleed exampleThe image is an example of another display, it is not this one

The static contrast ratio of above TV is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More the better.

Also, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.

If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.

LG did not state a static contrast ratio specification for this TV. So we have to make an assumption again based on the TV's other specs. In general, IPS panels come with a static contrast ratio between 700:1 - 1500:1. Considering its a 4K TV, we can guess the ratio would be >= 1200:1.

HLG (Hybrid Log Gamma) and HDR10 are also supported on this TV, so that's a plus.

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 aren't into gaming, you can safely ignore these specifications. But if you are also planning to use the TV for playing games or use it as a PC monitor, you should get a TV that features the lowest input lag and response time.

Sadly, we cannot find the input lag specification for this unit. But since this is not a cheap TV, we can expect an input lag of less than 20ms.

What is Input Lag and Why it matters ?

This lag is the amount of time at which inputs changes the content of the screen. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.

For best of both worlds, get a TV that comes with an input lag and response time of < 20ms.

Ergonomics and Dimensions

Now, speaking of ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. Swivel, Tilt or Pivot features are not supported on this unit.

The vertical and horizontal measurements of this TV are 48.46 inches and 30.35 inches respectively.

It is 2.86 inches thick. In total this TV weighs around 10.8 Kgs including stand. Without stand, it weighs 10.7 KGs.
