The 55UQ9000PUD is a 55 inch 4K TV from LG, launched in the year 2022. It comes with a True 8-bit IPS panel.
It can achieve a maximum resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 80 ppi.
After screen size and resolution, the next most important specification to look for in a display is its Color Reproduction Accuracy (defined by its color gamut specification).
LG has not provided a color gamut rating for this TV. But don't worry, we have other means to guess that.
Considering 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 will be Lifelike! Meaning it will produce color accurate images AS IT IS intended.
What is Color gamut ?
Color gamut specification of a display is the measurement of the range of colors that the display can show.
What this means is, this specification determines the ability of a TV to produce accurate colors. A TV with low gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
Different manufacturers use different units to specify color gamut. Viz — sRGB (most popular), NTSC 1953, DCI P3 Adobe RGB and rec.2020.
But you don't need to worry about that, here is a chart that you can use to choose a TV with good color accuracy.
Now, after color gamut, the static contrast ratio of a TV holds almost equal role in picture quality.
Understanding the 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. Also, such displays may suffer from backlight bleeds such as below:The image is an example of another display, it is not this one
Clearly this will affect your experience, especially in a dark room.
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, so lesser detail overall.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
We couldn't find a static contrast ratio specification for this TV. Again we have to make an assumption based on the TV's other specs. FYI — IPS panels come with a static contrast ratio between 700:1 - 1500:1. For a 4K TV, we can assume the ratio of LG 55UQ9000PUD to be atleast 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 the TV can achieve is 250 nits, powered by Direct LED backlight.
If you are planning to use your TV just for content consumption, you can safely ignore these specs. But if you are also going to use the TV for gaming or use it as a PC monitor, make sure to get a TV with the lowest input lag and response time.
Sadly, there is no specification for input lag on this TV. But as this is not a cheap TV from LG, input lag on this TV could be 20ms or below.
Understanding Input lag and response time
This lag is the latency at which your inputs changes the content of your TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, get a TV that comes with 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 TV measures 55 inches vertically and 48.62 inches horizontally.
It is 2.26 inches thick.
It weighs around 14.0 kilograms and 0.2 kgs extra if you include stand. So plan your space accordingly.
Hardware and Audio
