The 75QNED80UQA is a 75 inch 4K TV from LG, launched in the year 2022. It comes with a True 10-bit IPS panel. The maximum resolution it can display is 3840 x 2160 @ 120 Hz with a pixel density of 59 ppi.
Picture Quality
After screen size and resolution, the next important feature 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 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 should be Lifelike! It is capable of producing accurate colors.
What Color Gamut means ?
Color gamut specification of a TV is the measurement of the range of colors that it can produce.
A display with poor color reproduction will produce undersaturated colors that will spoil the immersion.
Different manufacturers use different units to specify color gamut. Viz — sRGB (standard RGB), NTSC 1953, DCI P3 etc.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
After color gamut, you should look at the static contrast specification as it impacts the picture quality substantially.
What is Static Contrast ratio ?
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. Also, such displays are likely to suffer from backlight bleeds such as below:
The image is an example of another display, it is not this oneThis will impact your viewing experience considerably, especially in a dark room.
Note that, 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 show both dark gray and black as black, so lesser detail overall.
This TV comes with a static contrast ratio of 8000:1., enough to display deep blacks. For the record, it also comes with local dimming which is a plus.
HLG (Hybrid Log Gamma) and HDR10 are also supported on this TV.
Coming to brightness, it can go as bright as 250 nits. The backlight of this TV is powered by Edge LED (Local Dimming) technology.
Gaming Performance
If you are going to use your TV other than watching videos — like as a PC monitor or for gaming purposes, make sure to get a TV that features the lowest input lag. For gaming, both input lag and response time impacts the performance.
Sadly, there is no specification for input lag on this TV. But 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 latency at which key-presses or mouse movements changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
But ideally, look for a TV that features 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. The unit doesn't come with either Swivel, Tilt or Pivot support.
Vertically, the TV measures 75 inches and horizontally 65.9 inches.
Speaking of thickness, it is just 1.8 inches thick. Overall it weighs approximately 36.92 Kgs including stand. Without stand, it weighs 35.88 kgs. So plan your space accordingly.
