The 65UQ90009LA is a 65 inch 4K TV from LG. It was launched in 2022. It comes with a True 8-bit IPS panel.
It can achieve a max resolution of 3840 x 2160 @ 60 Hz with a pixel density of 68 ppi.
Now, the very next specification of a display that will impact your viewing experience is Color Gamut.
LG has not provided a color gamut specification for this TV. So we have to take a guess. Considering the TV features amassive 65 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 will be Lifelike! It is capable of producing accurate colors AS IT IS intended.
Understanding the Color Gamut Specification
Color gamut specification of a TV is a measure of the range of colors that the TV can produce.
In other words, it determines the ability of a display 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,sRGB (standard RGB), NTSC, DCI P3 etc. It is upto the manufacturer which one they choose.
But don't worry, here is a chart that will help you choosing a TV with good color accuracy.
After color gamut, you should look at the static contrast specification as it influences the picture quality substantially.
Understanding Static Contrast
A TV with low static contrast ratio will not produce deep blacks and can bleed backlight as in the images below:The image is an example of another display, it is not this one
The static contrast ratio of above TV is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More is better.
Think of static contrast as another dimension to details — just like resolution. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus lesser detail overall.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
LG did not define static contrast ratio specification for this TV. 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 would be atleast 1200:1 or above.
HDR is also supported on this TV in form of HDR10 Pro and HLG (Hybrid Log Gamma).
As for brightness, it can go as bright as 320 nits with the help of Direct LED backlight.
If you are planning to use your TV only for content consumption, you can ignore these specifications. But if you are also planning to use the TV for gaming or use it as a PC monitor, you would want to take a TV that features the lowest input lag and response time.
The input lag on the LG 65UQ90009LA is 10.2 ms and its minimum response time is 9.3 ms. It is good enough for both casual and competitive/FPS games.
Understanding Input lag and response time
This lag is the amount of time at which key-presses or mouse movements changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, look for a TV that features an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Now, coming to ergonomics — VESA mount is supported on this TV with an interface size of 300 x 300 mm. However, there is no Swivel, Tilt or Pivot feature support on this TV.
The vertical and horizontal measurements of this TV are 57.24 inches and 35.39 inches respectively. It is just 2.27 inches thick. It weighs around 21.5 Kgs and 0.3 kgs extra if you include stand. So plan your space accordingly.
