The 50NANO776QA is a 50 inch 4K TV from LG. It was launched in 2022. It features a 10-bit VA panel. It can achieve a maximum resolution of 3840 x 2160 @ 60 Hz with a pixel density of 89 ppi.
Picture Quality
After screen size and resolution, the next most important specification of a display is its Color Reproduction Accuracy (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 is capable of producing accurate colors out of the box.
Understanding Color Gamut
Color gamut spec of a display is the measurement of the range of colors that it can show.
In other words, this specification tells the ability of a display to produce accurate colors. A TV with low color gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
It is specified in different units - sRGB(most popular), 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.
Now, after color gamut, you should look at the static contrast specification as it influences the picture quality the same way.
Understanding the static contrast specification
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.
This tells the intensity of black levels. That is, a TV with SC ratio < 1000:1 will produce black images something like this:

Moreover, such TVs may suffer from backlight bleeds that will impact your experience — as shown below.

Other than black levels, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
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. If you are reading our blogs, you may already know that Most always come with impressive contrast ratios. As you know, this TV features the same, so the static contrast ratio would be easily atleast 3000:1 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 250 nits. The panel of this TV is powered by Direct LED backlight technology.
Gaming Performance
If you are planning to use your TV just for content consumption, you can 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 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, input lag on this TV could be 20ms or below.
What is Input lag ?
This lag is the latency at which your key-presses or mouse movements changes the content of the screen. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, get a TV that features an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The TV measures 50 inches vertically and 44.13 inches horizontally.
It is 2.27 inches thick. It weighs approximately 12.2 kilograms, another 0.2 kgs including stand.
Now, coming to ergonomics — VESA mount is supported on this TV with an interface size of 200 x 200 mm. However, there is no Swivel, Tilt or Pivot feature support on this TV.
Hardware and Audio
The internals of this TV is powered by a 4-Core CPU. However, LG didn't provide any specification on the RAM on the TV's official specsheet.
The Operating System on this TV is webOS 22.
For display connectivity, there are three HDMI 2.0 ports on this TV.
To connect USB devices, it includes two USB 2.0 ports. Other connectivity ports include — 1x Satellite In (F-type female), 1x Antenna (RF) (female), 1x CI+ 2.0 and 1x Ethernet RJ45.
Wireless connectivity options on the LG 50NANO776QA include a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth 5.0 and DLNA.
Speaking of speakers, LG has provided 2 x 10W built-in speakers on the TV.
Speaking of power consumption, on average, it consumes 68 Watts and on standby, it uses 0.5 Watts.
Both 110V and 220V lines are supported on this unit.
