The XR-75X90K NA is a 75 inch 4K TV from Sony, launched in the year 2022. It comes with a True 10-bit IPS panel.
It can display a maximum resolution of 3840 x 2160 @ 120 Hz with a pixel density of 59 ppi.
After screen size and resolution, the next important feature of a display that impacts picture quality is Color Gamut.
This TV doesn't come with a color gamut specification, so we have to take a guess.
Now, since 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! Meaning it will produce color accurate images.
What Color Gamut means ?
Color gamut spec of a TV indicates the range of colors that the TV can produce.
A TV with poor color accuracy will produce undersaturated colors that will spoil the immersion.
Different manufacturers use different units to specify color gamut. Such as — sRGB, NTSC 1953, DCI P3 Adobe RGB and rec.2020.
But you don't need to worry about that, here is a chart that will help you choosing a TV with good color accuracy.
Next in the list of important specifications is Static Contrast.
Why its important?
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. Moreover, such TVs often suffer from backlight bleeds such as below:The image is an example of another display, it is not this one
Needless to say, this will impact your viewing experience, especially in a dark room.
Also, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
If given a choice, always 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 produce deep blacks. The panel comes with local dimming which is a plus.
HDR is also supported on this TV in form of Dolby Vision, HDR10 and HLG (Hybrid Log Gamma).
As for brightness, it is can achieve a peak brightness of 250 nits, powered by Direct LED (Full-Array Local Dimming) backlight.
If you are planning to use your TV solely for content consumption, 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 get a TV that features the lowest input lag and response time.
Sadly, we cannot find the input lag specification for this unit. Now, as this is not a cheap TV, we can expect an input lag of less than 20ms.
What is Input lag ?
This lag is the latency at which your inputs changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
But ideally, get a TV that features an input lag and response time of less than 20ms.
