ABOUT THIS TV

Launched in the year 2022, the 55UQ91006LA is a 55" 4K TV from LG. It comes with a 10-bit IPS panel.

It can display a maximum resolution of 3840 x 2160 @ 60 Hz with a pixel density of 80 ppi.

Picture Quality

After screen size and resolution, the next important feature of a display that will impact your viewing experience is its Color Gamut.

This TV doesn't come with a color gamut specification, so we have to make an assumption based on its panel type. 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. The color accuracy on this TV should be Lifelike! Meaning it is capable of producing color accurate images AS IT IS intended.

Understanding the Color Gamut Specification

Color gamut spec of a TV is the measurement of the range of colors that the display can display.

A TV with poor color accuracy will produce undersaturated/washed out colors that will spoil the immersion.

Different manufacturers use different measurement standards to specify color gamut. Viz — sRGB (most popular), NTSC, DCI P3 to name a few.

But don't worry, below is a chart that you can use to choose a TV with good color accuracy.

Color Gamut Chart

Next in the list of important specifications that will impact your experience is Static Contrast.

What is Static Contrast ?

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:

Obviously this will impact your viewing experience, especially in a dark room.

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 show both dark gray and black as black, so lesser detail overall.

There's no mention of this specification in this TV's official specsheet. Once again we have to take a guess based on the TV's other specifications. Most IPS panels come with a static contrast ratio between 700:1 - 1500:1. As for a 4K TV, we can assume the ratio to be 1200:1 or above.

HDR is also supported on this TV in form of HDR10 Pro and HLG (Hybrid Log Gamma).

Coming to brightness, the peak luminance it can achieve is 250 nits. The backlight used on the panel is Direct LED.

Gaming Performance

If you are not planning to game on this TV, you can safely ignore these specs. But if you are also going to use the TV for playing games or use it as a PC monitor, you would want to get a TV with the lowest input lag and response time.

Unfortunately, there is no specification for input lag on this TV. But since this is not a cheap TV from LG, input lag on this TV could be 20ms or below.

What is Input lag ?

This lag is the amount of time at which your 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 features an input lag and response time of < 20ms.

Dimensions and Ergonomics

The TV measures 55 inches vertically and 48.62 inches horizontally. It is 2.26 inches thick. Overall this TV weighs around 15.4 Kgs including stand. Without stand, it weighs 14.0 Kilograms. So plan your space accordingly.

Speaking of ergonomics — a VESA mount with interface size of 300 x 200 mm is provided for wall-mounting. However, there is no Swivel, Tilt or Pivot feature support in this TV.

Hardware and Audio

The LG 55UQ91006LA comes with a Quad Core CPU. There is no mention on the available RAM on the TV's specsheet.

To power its UI, the TV runs webOS 22 Operating System.

For display connectivity, LG has provided two HDMI 2.0 ports and two HDMI 2.1 ports on this TV.
