Launched in the year 2022, the KD-75X80K is a 75" 4K TV from Sony. It features a 10-bit IPS panel. It can display a maximum resolution of 3840 x 2160 @ 60 Hz with a pixel density of 59 ppi.
After screen size and resolution, the next important specification of a display that defines picture quality is Color Gamut.
Sony did not provide a color gamut rating for this TV. So we have to take a guess.
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. Undoubtedly The color quality on this TV will be Lifelike! It will produce accurate colors by default.
Understanding Color Gamut
Color gamut specification of a display indicates the range of colors that the display can show.
In layman terms, this specification determines the ability of a display to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 etc.
But you don't need to worry about that, below 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 holds almost equal role in picture quality.
The importance of static contrast ratio
There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
Static contrast specification tells the intensity of black levels. That is, a TV with SC ratio less than 1000:1 will produce black images something like this:
Moreover, such TVs are likely be prone to backlight bleeds that will affect your experience — as shown below.The image is an example of another display, it is not this one
Also note, 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.
This TV features a static contrast ratio of 8000:1., well enough to produce deep blacks. The panel comes with local dimming backlight technology which is a plus.
Dolby Vision, HDR10 and HLG (Hybrid Log Gamma) are also supported on this TV.
As for brightness, it is can produce a maximum brightness of 250 nits, powered by Direct LED backlight technology.
If you aren't interested in gaming, you can safely ignore these specifications. But if you are also going to use the TV for playing games or use it as a PC monitor, make sure to get a TV with the lowest input lag and response time.
Unfortunately, there is no specification for input lag on this TV. Now, since this is not a cheap TV, we can expect an input lag of less than 20ms.
What is Input Lag and Why it matters ?
This lag is the amount of time at which device inputs changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, get a TV that features an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The width of this TV is 65.94 inches while its height is 40.98 inches. In terms of thickness, it is just 2.87 inches thick. Overall this TV weighs approximately 33.5 kgs including stand. Without stand, it weighs 32.2 KGs. So plan your space accordingly.
Now, speaking of ergonomics — VESA mount is supported on this TV with an interface size of 300 x 300 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.
