The XR-65A80K NA is a 65 inch 4K TV from Sony, launched in the year 2022. It comes with a True 10-bit OLED panel.
It can achieve a maximum resolution of 3840 x 2160 @ 120 Hz with a pixel density of 68 ppi.
After screen size and resolution, the next important spec of a display that impacts picture quality is its Color Gamut.
This TV doesn't provide a color gamut specification, so we have to take a guess. Now, since the TV comes with an OLED panel, so we can conclude that the equivalent sRGB coverage of this TV would be far above 100%.
Understanding Color Gamut
Color gamut specification of a display is the measurement of the range of colors that it can display.
What this means is, it determines the ability of a TV to produce accurate colors. A TV with low gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 Adobe RGB, 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.
Now, after color gamut, you should look at the static contrast specification as it influences the picture quality substantially.
Understanding the static contrast ratio of a TV
A TV with high enough static contrast ratio will produce deep blacks while a TV with low contrast ratio (<1000:1) will produce images that will look dusty as shown below.
As you see, this will impact your experience considerably.
Like resolution, the static contrast ratio is also equally responsible for details. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus 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 Infinity:1.. So no need to worry about this.
HDR is also supported on this TV in form of Dolby Vision, HDR10 and HLG (Hybrid Log Gamma).
As for brightness, it is capable of producing a maximum luminance of 250 nits.
If you are going to use a TV other than using it as a TV — like as a PC monitor or for gaming purposes, you would want to get a TV that features the lowest input lag. For gaming, both the input lag and response time impacts the performance.
The input lag on this TV is 5 ms and its minimum response time is 1 ms. So its a go-to TV if you are interested in gaming.
What is Input lag ?
This lag is the amount of time at which device inputs changes the content of the TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
For best of both worlds, look for a TV that comes with an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Speaking of 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. Swivel, Tilt or Pivot features are not supported on this unit.
Vertically, the TV extends upto 65 inches (adjustable +1.65") and horizontally 57 inches.
Coming to thickness, it is 2 inches thick. It weighs approximately 23.0 kilograms and 1.6 kgs extra including stand.
Hardware and Audio
For display connectivity, there are two HDMI 2.0 ports, two HDMI 2.1 ports and one AV Composite In 3.5 mm jack port on this TV.
To connect USB devices, it includes two USB ports. Other connectivity ports include — 1x Cable/Antenna In (F-type female), 1x RS232 (C) and 1x Ethernet RJ45.
Regarding wireless connections, you will have — Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth and DLNA.
Now, for audio, it is packaged with 3 x 10W speakers. It also comes with a built-in subwoofer. So you don't have to invest on an external sound system.
As for power usage, the TV consumes 114.24 watts on average and 0.5 watts on standby.
For powering this unit, you'll need either a 110V or 220V outlet @ 50Hz-60Hz.
