The XR-65X90K is a 65 inch 4K TV from Sony. It was launched in 2022. It features a True 10-bit VA panel. It can display a maximum resolution of 3840 x 2160 with a refresh rate of 120 Hz and pixel density of 68 ppi.
After screen size and resolution, the next important feature of a display that impacts picture quality is its Color Gamut.
This TV doesn't come with a color gamut specification, so we have to make an assumption based on its panel type. Now, since the TV features a big 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. The color accuracy on this TV will be Lifelike! It is capable of producing color accurate images AS IT IS intended.
Understanding the Color Gamut Specification
Color gamut specification of a TV is the measurement of the range of colors that the display can display.
A display with poor color reproduction will produce undersaturated colors that will spoil your immersive experience.
It is specified in different units - sRGB(most popular), NTSC, DCI P3 etc.
But you don't need to worry about that, below is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, the static contrast ratio of a TV holds almost equal role in picture quality.
Why its important?
The 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. Apart from this, such displays may suffer from backlight bleeds such as this: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, 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, I will 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., good enough to produce 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 Dolby Vision, HDR10 and HLG (Hybrid Log Gamma).
As for brightness, it is can achieve a peak brightness of 250 nits, which is powered by Direct LED (Full-Array Local Dimming) backlight.
If you are not planning to game on this TV, you can safely ignore these specifications. But if you are also going to use the TV for gaming or use it as a PC monitor, you should take a TV with the lowest input lag and response time.
Unfortunately, there is no specification for input lag on this TV. Now, since this is not a cheap TV from Sony, we can expect an input lag of less than 20ms.
Understanding Input lag and response time
This lag is the latency at which key-presses/mouse movements changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, look for a TV that has 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. There is no Swivel, Tilt or Pivot feature support in this TV.
The width of this TV is 57.17 inches while its height is 33.98 inches ( adjustable upto 1.57" ).
It is just 2.83 inches thick.
It weighs approximately 22.9 Kgs and an additional 1.1 kgs including stand.
Hardware and Audio
The TV is powered by 4-Core CPU. However, Sony didn't provide any info about the total RAM on this TV.
For display connectivity, there are four HDMI 2.1 ports and one AV Composite In 3.5 mm jack port on this TV.
To connect USB devices, you will have two USB ports. Other connectivity ports include — 1x Satellite In (F-type female), 1x Antenna (RF) (female), 1x CI+ 1.4 and 1x Ethernet RJ45.
For connecting to this TV wirelessly, the manufacturer has provided a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth and DLNA.
For audio, it is packaged with 2 x 10W speakers.
Now, coming to power usage, on average, this TV consumes around 114.24W and on standby, it uses 0.5 W.
For powering this unit, you'll need either a 110V or 220V outlet @ 50Hz-60Hz.
