The 50UQ7590PUB is a 50 inch 4K TV from LG, launched in the year 2022. It comes with a True 8-bit VA panel. The maximum resolution it can display is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 89 ppi.
After screen size and resolution, the next most important feature to look for in a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.
LG has not provided a color gamut specification for this TV. But don't worry, we have other means to guess that.
Considering the TV features a 50 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 will be Lifelike! It is capable of producing color accurate images AS IT IS intended.
What is Color gamut ?
Color gamut spec of a TV indicates the range of colors that the display can display.
In layman terms, it indicates the ability of a display to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 etc.
But you don't need to worry about that, below is a chart that will help you choosing a TV with good color accuracy.
Now, next in the list of important specifications that will impact your experience is Static Contrast.
Understanding the static contrast ratio
A TV with high enough static contrast ratio will produce deep blacks while a TV with low contrast ratio (<1000:1) will produce images that will look muddy as shown in the below image.
As you see, this will rob your experience considerably.
Also, 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, 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 specify static contrast specification for this TV. Once again we have to make an assumption based on the TV's other specs. For a TV with VA panel, the static contrast ratio will surely atleast be 3000:1 or above.
HDR is also supported on this TV in form of HDR10 Pro and HLG (Hybrid Log Gamma).
As for brightness, the peak brightness the LG 50UQ7590PUB can produce is 250 nits, powered by Direct LED backlight technology.
If you are planning to use your TV just for content consumption, you can ignore these specifications. 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 that features the lowest input lag and response time.
Unfortunately, LG did not specify the input lag on this unit. But since this is not a cheap TV, we can expect an input lag of less than 20ms.
What is Input lag ?
This lag is the latency at which your key-presses or mouse movements changes the content of your display. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, look for a TV that has an input lag and response time of less than 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 50 inches and horizontally 44 inches. It is 2.2 inches thick. Overall, it weighs 11.2 kgs.
