Launched in the year 2022, the 75NANO766QA is a 75" 4K TV from LG. It comes with a 10-bit IPS panel.
It can achieve a maximum resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 59 ppi.
Picture Quality
After screen size and resolution, the next important feature of a display that defines picture quality is Color Gamut.
LG has not provided a color gamut rating for this TV. But don't worry, we have other means to guess that.
As this TV features a big 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. Undoubtedly The color quality on this TV will be Lifelike! It will produce color accurate images.
Understanding Color Gamut
Color gamut specification of a TV indicates the range of colors that the TV can show.
Put Simply, it indicates the ability of a TV to produce accurate colors. A TV with low color gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
Different manufacturers use different units to specify color gamut. Such as — sRGB, NTSC 1953, DCI P3 to name a few.
But don't worry, here is a chart that you can use to choose a TV with good color accuracy.
Next in the list is Static Contrast.
Understanding the static contrast ratio of a TV
The static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (<1000:1) will not produce deep blacks. Moreover, such displays may suffer from backlight bleeds such as this:
The image is an example of another display, it is not this oneThis will impact your viewing experience, especially in a dark room.
Other than black levels, a TV with high constrast ratio lets 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.
LG did not state a static contrast ratio specification for this TV. Once again we have to take a guess based on the TV's other specs. In general, IPS panels come with a static contrast ratio between 700:1 - 1500:1. Now, for a 4K TV, we can assume the ratio of LG 75NANO766QA would be 1200:1 or above.
HDR is also supported on this TV in form of HDR10 Pro and HLG (Hybrid Log Gamma).
Coming to brightness, it can go as bright as 250 nits with the help of Direct LED backlight.
Gaming Performance
Now if you are going to use your TV other than watching videos — like as a PC monitor or Gaming, you should take a TV that features the lowest input lag. For gaming however, both the input lag and response time impacts the performance.
Unfortunately, we cannot find the input lag specification for this unit. Now, as this is not a cheap TV from LG, we can expect an input lag of less than 20ms.
Understanding Input lag and response time
This lag is the latency at which 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.
Although for better experience, look for a TV that features an input lag and response time of < 20ms.
Ergonomics and Dimensions
Now, coming to ergonomics — VESA mount is supported on this TV with an interface size of 400 x 400 mm. There is no Swivel, Tilt or Pivot feature support in this TV.
The TV measures 75 inches vertically and 66 inches horizontally.
It is 2.36 inches thick. It weighs approximately 31.4 Kgs and 3.2 kgs extra if you include stand.
