The 70NANO766QA is a 70 inch 4K TV from LG. It was launched in 2022. It comes with a 10-bit VA panel. The max. resolution it can display is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 63 ppi.
Picture Quality
After screen size and resolution, the next most important spec of a display is its Color Reproduction Accuracy, which is 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 70 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 accuracy on this TV should be Lifelike! Meaning it is capable of producing color accurate images.
Understanding the Color Gamut Specification
Color gamut specification of a display is the measurement of the range of colors that the TV can show.
A display with poor color reproduction will produce washed out colors that will not be pretty to look at.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 etc.
But you don't need to worry about that, here is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, you should look at the static contrast specification as it impacts 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 specification defines the intensity of black levels. That is, a TV with SC ratio < 1000:1 will produce black images something like this:
Apart from that, such TVs are likely to suffer from backlight bleeds that will affect your experience — as shown below.
The image is an example of another display, it is not this oneThink of static contrast as another dimension to details — just like resolution. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus lesser detail overall.
There is no mention of this specification in this TV's official specsheet. So once again we have to make an assumption based on the TV's other specifications. VA panels have impressive contrast ratios. This TV comes with 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.
Coming to brightness, the peak brightness the LG 70NANO766QA can achieve is 250 nits. The backlight of this TV is powered by Direct LED technology.
Gaming Performance
If you are planning to use your TV other than watching videos — like as a PC monitor or for gaming purposes, you would want to get a TV that features the lowest input lag. For gaming, both the input lag and response time impacts the performance.
Sadly, there is no specification for input lag on this TV. Now, since this is not a cheap TV from LG, input lag on this TV could be 20ms or below.
Understanding Input lag and response time
This lag is the amount of time at which your inputs changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, get a TV that has an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Coming to ergonomics — a VESA mount with interface size of 400 x 400 mm is provided for wall-mounting. There is no Swivel, Tilt or Pivot feature support in this TV.
The width of this TV is 61.5 inches while its height is 38.82 inches. It is 2.36 inches thick. It weighs around 28.5 Kgs, another 3.2 kgs including stand. So plan your space accordingly.
