The XR-75X90K is a 75 inch 4K TV from Sony. It was launched in 2022. It features a True 10-bit IPS panel. The maximum resolution it can display is 3840 x 2160 @ 120 Hz with a pixel density of 59 ppi.
Picture Quality
After screen size and resolution, the next most important feature of a display is its Color Reproduction, which is defined by its color gamut specification.
Sony did not provide a color gamut specification for this TV. So we have to take a guess.
Considering the TV features a 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 accuracy on this TV should be Lifelike! Meaning it is capable of producing accurate colors by default.
Understanding Color Gamut
Color gamut specification of a display indicates the range of colors that the TV can produce.
A panel with poor color reproduction will produce washed out colors that will not be pretty to look at.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 to name a few.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
After color gamut, next in the list is Static Contrast.
What is 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 specification defines 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 may suffer from backlight bleeds that will affect 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, 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., good enough to achieve deep blacks. For the record, it also comes with local dimming technology which is a plus.
HDR is also supported on this TV in form of Dolby Vision, HDR10 and HLG (Hybrid Log Gamma).
Coming to brightness, it can go as bright as 250 nits. The backlight used on the panel is Direct LED (Full-Array Local Dimming).
Gaming Performance
If you are planning to use a TV other than using it as a TV — like as a PC monitor or for gaming purposes, make sure to get a TV with lowest input lag. For gaming however, both input lag and response time affects the performance.
Unfortunately, Sony did not specify the input lag on this unit. 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 inputs changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, look for a TV that comes with an input lag and response time of < 20ms.
Ergonomics and Dimensions
Speaking of 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 extends upto 75 inches (adjustable +1.57") and horizontally 65.94 inches.
Coming to thickness, it is 2.87 inches thick.
It weighs 34.4 kgs and 1.4 kgs extra if you include stand. So plan your space accordingly.
