Launched in the year 2022, the KD-65X75K is a 65" 4K TV from Sony. It features a 10-bit IPS panel. The max. resolution it can display is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 68 ppi.
Picture Quality
Now, the very next feature of a display that defines picture quality is its Color Gamut.
Sony has not provided a color gamut rating for this TV. So we have to take a guess. Considering the TV features amassive 65 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! It is capable of producing color accurate images AS IT IS intended.
What Color Gamut means ?
Color gamut specification of a TV is a measure of the range of colors that the TV can display.
A display with poor color accuracy will produce washed out colors that will spoil the immersion.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 Adobe RGB, rec.2020. It is upto the manufacturer which one they choose.
But don't worry, 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 influences the picture quality substantially.
The importance of static contrast ratio
The static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (less than 1000:1) will not produce deep blacks. Moreover, such TVs are likely to suffer from backlight bleeds such as this:
The image is an example of another display, it is not this oneObviously this will impact your experience, especially in a dark room.
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 comes with a static contrast ratio of 8000:1., well enough to achieve deep blacks. For the record, it also comes with local dimming feature which is a plus.
HDR is also supported on this TV in form of HDR10 and HLG (Hybrid Log Gamma).
Coming to brightness, it can go as bright as 250 nits, powered by Direct LED backlight.
Gaming Performance
If you are planning to use your TV solely for content consumption, you can safely ignore these specs. But if you are also going to use the TV for gaming or use it as a PC monitor, you would want 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, 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 key-presses or mouse movements changes the content of your display. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
For best of both worlds, get a TV that has an input lag and response time of < 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 65 inches and horizontally 57.6 inches. It is just 3.43 inches thick.
In total it weighs around 22.1 kilograms including stand. Without stand, it weighs 21.4 kgs.
