The 43NANO776QA is a 43 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 with a refresh rate of 60 Hz and pixel density of 103 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).
LG has not provided a color gamut rating for this TV. So we have to take a guess. As this TV comes with a 10bit VA panel, we can safely assume its equivalent sRGB coverage to be 100% or above. The color accuracy on this TV will be Lifelike!
Understanding Color Gamut
Color gamut specification of a TV is a measure of the range of colors that the display can show.
A TV with poor color accuracy will produce undersaturated colors that will spoil your immersive experience.
Different manufacturers use different measurement standards to specify color gamut. Viz — sRGB, NTSC 1953, DCI P3 etc.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
Other than color accuracy, the static contrast of a TV similarly impacts its picture quality.
The importance of static contrast ratio
A TV with low static contrast ratio will not produce deep blacks and possibly can bleed backlight as shown in the below image:

The above TV's static contrast is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More the 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.
LG did not specify static contrast specification for this TV. So we have to make an assumptionagain. If you are reading our blogs, you may already know that Most have impressive contrast ratios. As you know, this TV features the same, so the static contrast ratio would be easily atleast 3000:1 or above.
HDR10 Pro and HLG (Hybrid Log Gamma) are also supported on this TV.
As for brightness, it can go as bright as 250 nits. The backlight of this TV is powered by Direct LED technology.
Gaming Performance
If you are planning to use your TV solely 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, make sure to take a TV that features 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, we can expect an input lag of less than 20ms.
What is Input lag ?
This lag is the latency at which your device inputs 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 comes with an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The vertical and horizontal measurements of this TV are 38 inches and 24.49 inches respectively.
It is just 2.27 inches thick.
Overall the TV weighs approximately 9.3 Kgs (including stand). Without stand, it weighs 9.2 Kgs.
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 200 x 200 mm. Swivel, Tilt or Pivot features are not supported on this unit.
Hardware and Audio
The internals of this TV is powered by 4-Core CPU. However, we could'nt find any specification about the total RAM on this TV.
The Operating System on this TV is webOS 22.
For display connectivity, LG has provided 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 this TV include a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth 5.0 and DLNA.
The Audio unit of this TV is powered by 2 x 10W speakers.
As for power consumption, the TV uses 54W on average and 0.5W on standby.
For powering this unit, you'll need either a 110V or 220V outlet @ 50Hz-60Hz.
