The KD-55X80K is a 55 inch 4K TV from Sony. It was launched in 2022. It features 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 80 ppi.
Picture Quality
After screen size and resolution, the next important specification of a display that impacts picture quality is Color Gamut.
This TV doesn't provide a color gamut specification, but don't worry, we have other means to guess that.
Considering the TV features a big 55 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! Meaning it will produce accurate colors.
What is Color gamut ?
Color gamut spec of a TV indicates the range of colors that the display can display.
A TV with poor color reproduction will produce washed out colors that will not be pretty to look at.
Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (standard RGB), NTSC, DCI P3 Adobe RGB and rec.2020.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
Now, after color gamut, the static contrast of a TV also impacts its picture quality.
The importance of static contrast ratio
A TV with low static contrast ratio will not produce deep enough blacks and possibly bleed backlight as shown in the below image:
The image is an example of another display, it is not this oneThe above TV's static contrast is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More is better.
Also, 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.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV features a static contrast ratio of 8000:1., enough to achieve deep blacks and eye-catching visuals. The panel comes with local dimming which is a plus.
Dolby Vision, HDR10 and HLG (Hybrid Log Gamma) are also supported on this TV.
Coming to brightness, the peak luminance it can achieve is 250 nits. The panel of this TV is powered by Direct LED backlight technology.
Gaming Performance
If you are not planning to game on this TV, you can ignore these specifications. But if you are also going to use the TV for gaming or use it as a PC monitor, make sure to take a TV with the lowest input lag and response time.
Unfortunately, Sony did not specify the input lag on this unit. But as 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 your device inputs changes the content of the 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 < 20ms.
Dimensions and Ergonomics
The TV measures 55 inches vertically and 48.54 inches horizontally. Coming to thickness, it is 2.83 inches thick. Overall this TV weighs around 16.9 Kgs including its stand. Without stand, it weighs 15.9 Kgs. So plan your space accordingly.
Now, coming to ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 300 x 300 mm. The unit doesn't come with Swivel, Tilt or Pivot support.
