The 75NANO756QA is a 75 inch 4K TV from LG, launched in the year 2022. It comes with a 10-bit IPS panel. It can display a max resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 59 ppi.
After screen size and resolution, the next important specification to look for in a display is its Color Reproduction (defined by its color gamut specification).
This TV doesn't provide a color gamut specification, so we have to make an assumption based on its panel type. Considering the TV features amassive 75 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! Meaning it will produce color accurate images AS IT IS intended.
Understanding the Color Gamut Specification
Color gamut specification of a TV is a measure of the range of colors that the display can show.
A TV with poor color reproduction will produce undersaturated/washed out colors that will not be pretty to look at.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 Adobe RGB, rec.2020.
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 specification 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 below:The image is an example of another display, it is not this one
The static contrast ratio of above TV is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More is better.
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 produce less shades of colors, so lesser detail overall.
We couldn't find a static contrast ratio specification for this TV. Once again we have to take a guess based on the TV's other specifications. Most IPS panels come with a static contrast ratio between 700:1 - 1500:1. As for a 4K TV, we can imagine the ratio would be no less than 1200:1.
HDR is also supported on this TV in form of HDR10 Pro and HLG (Hybrid Log Gamma).
As for brightness, it is capable of producing a peak brightness of 250 nits, which is powered by Direct LED backlight.
Now if you are planning to use your TV other than using it as a TV — say as a PC monitor or for gaming purposes, you should get a TV with lowest input lag. For gaming, both the input lag and response time impacts the performance.
Sadly, 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.
Understanding Input lag and response time
This lag is the amount of time at which key-presses/mouse movements changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
But ideally, get a TV that comes with an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Coming to ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 400 x 400 mm. Swivel, Tilt or Pivot features are not supported on this unit.
Vertically, the TV measures 75 inches and horizontally 66 inches.
It is just 2.36 inches thick.
Overall the TV weighs around 31.8 KGs (including stand). Without stand, it weighs 31.4 Kgs.
Hardware and Audio
The internals of LG 75NANO756QA is powered by a 4-Core CPU. There is no data on the RAM on the TV's specsheet.
To power its UI, the TV runs webOS 22 Operating System.
For display connectivity, LG has provided three HDMI 2.0 ports on this TV.
For connecting USB devices, you will have 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.
For wireless connections, the manufacturer has provided a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth 5.0 and DLNA.
Now, speaking of speakers, it is packaged with 2 x 10W speakers.
Now, coming to power usage, on average, this TV consumes about 138W. On standby, it takes 0.5 W.
For powering this unit, you'll need either a 110V or 220V outlet @ 50Hz-60Hz.
