Launched in the year 2022, the KD-75X80K NA is a 75" 4K TV from Sony. It comes with a 10-bit IPS panel.
The maximum resolution it can achieve is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 59 ppi.
Picture Quality
After screen size and resolution, the next most important specification of a display is its Color Reproduction (defined by its color gamut specification).
This TV doesn't come with a color gamut specification, but don't worry, we have other means to guess that.
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. The color quality on this TV should be Lifelike! It is capable of producing color accurate images by default.
Understanding Color Gamut
Color gamut specification of a display is a measure of the range of colors that the display can display.
A display with poor color accuracy will produce undersaturated/washed out colors that will spoil your immersive experience.
Different manufacturers use different units to define color gamut. Such as — sRGB (standard RGB), NTSC, DCI P3 Adobe RGB and rec.2020.
But don't worry, here is a chart that you can use to choose a TV with good color accuracy.
Next in the list that will impact your experience is Static Contrast.
Understanding Static Contrast
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.
Static contrast tells the intensity of black levels. That is, a TV with static contrast ratio less than 1000:1 may produce black images something like this:
Apart from this, such TVs are likely to suffer from backlight bleeds that will rob your experience — as shown below.
The image is an example of another display, it is not this oneOther than black levels, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV is rated with a static contrast ratio of 8000:1., enough to display deep blacks. The panel comes with local dimming which is a plus.
Dolby Vision, HDR10 and HLG (Hybrid Log Gamma) are also supported on this TV, so that's a plus.
As for brightness, it is can produce a maximum luminance of 250 nits. The backlight of this TV is powered by Direct LED technology.
Gaming Performance
If you are planning to use your TV just for content consumption, 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, you would want to take a TV that features the lowest input lag and response time.
Sadly, Sony did not specify the input lag on this unit. Now, since this is not a cheap TV, 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 key-presses or mouse movements changes the content of the TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
For best of both worlds, look for a TV that features an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Now, coming to ergonomics — VESA mount is supported on this TV with an interface size of 300 x 300 mm. However, there is no Swivel, Tilt or Pivot feature support in this TV.
Vertically, the TV measures 75 inches and horizontally 65.94 inches. In terms of thickness, it is 2.87 inches thick. In total this TV weighs around 22.5 KGs including its stand. Without stand, it weighs 32.2 KGs. So plan your space accordingly.
