The 50NANO75UQA is a 50 inch 4K TV from LG, launched in the year 2022. It comes with a 10-bit VA panel. The maximum resolution it can achieve is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 89 ppi.
Picture Quality
After screen size and resolution, the next important spec to look for in a display is its Color Reproduction (defined by its color gamut specification).
This TV doesn't come with a color gamut specification, so we have to take a guess. Now, since 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. The color quality on this TV should be Lifelike! It will produce accurate colors by default.
Understanding Color Gamut
Color gamut spec of a TV is the measurement of the range of colors that it can show.
In layman terms, this specification determines the ability of a display to produce accurate colors. A panel with low color 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 measurement standards to specify color gamut. Such as — sRGB (most popular), NTSC 1953, DCI P3 etc.
But you don't need to worry about that, here is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, the static contrast ratio of a TV has equally important role in picture quality.
Why its important?
A TV with low static contrast ratio will not produce deep enough blacks and can bleed backlight as shown in the images below:
The image is an example of another display, it is not this oneThe static contrast ratio of above TV is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More is better.
Other than black levels, a TV with high constrast ratio enables you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
However, we couldn't find a static contrast ratio specification for this TV. Again we have to take a guess 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 TV can produce is 250 nits. The backlight used on the panel is Direct LED.
Gaming Performance
If you aren't planning to game on this TV, you can safely ignore these specs. But if you are also planning to use the TV for gaming or use it as a PC monitor, you should take 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, input lag on this TV could be 20ms or below.
What is Input Lag and Why it matters ?
This lag is the amount of time at which your inputs changes the content of the TV. 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 has an input lag and response time of < 20ms.
Dimensions and Ergonomics
The width of this TV is 44.13 inches while its height is 27.87 inches. In terms of thickness, it is just 2.27 inches thick. It weighs 12.2 kilograms and 0.2 kgs extra if you include stand. So plan your space accordingly.
Coming to ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. The unit doesn't come with Swivel, Tilt or Pivot support.
Hardware and Audio
The LG 50NANO75UQA is powered by 4-Core CPU. There is no information about the total available RAM on the TV's specsheet.
The Operating System on this TV is webOS 22.
For display connectivity, there are three HDMI 2.0 ports on this TV.
For connecting USB devices, it includes two USB 2.0 ports. Other connectivity ports include — 1x Cable/Antenna In (F-type female), 1x RS232 (C) and 1x Ethernet RJ45.
Regarding wireless connectivity, the manufacturer has provided Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth 5.0 and DLNA.
Now, speaking of speakers, it is packaged with 2 x 10W built-in speakers.
As for power usage, the TV consumes 50.4 Watts on average and 0.5 Watts on standby.
For powering this unit, you'll need either a 110V or 220V outlet @ 50Hz-60Hz.
