The XR-55A80K is a 55 inch 4K TV from Sony. It was launched in 2022. It features a True 10-bit OLED panel.
It can achieve a max resolution of 3840 x 2160 @ 120 Hz with a pixel density of 80 ppi.
After screen size and resolution, the very next specification of a display that will impact your viewing experience is its Color Gamut.
This TV doesn't provide a color gamut specification, so we have to make an assumption based on its panel type. Now, since it comes with an OLED panel, so we can conclude that the equivalent sRGB coverage of this panel would be far above 100%.
Understanding Color Gamut
Color gamut spec of a display indicates the range of colors that the TV can produce.
A display with poor color reproduction will produce undersaturated colors that will not be pretty to look at.
Different manufacturers use different measurement standards to specify color gamut. Such as — sRGB, NTSC, DCI P3 to name a few.
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, next in the list of important specifications is Static Contrast.
Understanding the static contrast ratio of a TV
There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.
Static contrast tells the intensity of black levels. That is, a TV with SC ratio < 1000:1 will produce black images something like this:
Apart from this, 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 one
Other than black levels, a TV with high constrast ratio enables 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 comes with a static contrast ratio of Infinity:1. That's a plus for OLED TVs. So no need to worry about this.
Dolby Vision, HDR10 and HLG (Hybrid Log Gamma) are also supported on this TV.
Coming to brightness, it is can produce a peak brightness of 250 nits.
If you aren't 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 would want to get a TV that features the lowest input lag and response time.
The input lag on the Sony XR-55A80K is 5 ms and its minimum response time is 1 ms. Gamers gonna love this TV.
Understanding Input lag and response time
This lag is the latency at which inputs changes the content of your display. For casual Non-FPS games, input lag doesn't matter much.
But ideally, get a TV that comes with an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Coming to 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. The unit doesn't come with Swivel, Tilt or Pivot support.
The width of this TV is 48.31 inches while its height is 29 inches ( adjustable upto 1.65 in ). Coming to thickness, it is just 2 inches thick.
It weighs approximately 17.9 kgs and an additional 1.6 kgs if you include 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.
For connecting USB devices, it includes two USB ports. Other connectivity ports include — 1x CI+ 1.4, 1x Satellite In (Sub — F-type female), 1x Satellite In (Main — F-type female), 1x Antenna (RF) (female) and 1x Ethernet RJ45.
For wireless connectivity, the manufacturer has provided a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth and DLNA.
Speaking of speakers, it is packaged with 3 x 10W built-in speakers. It also comes with a built-in subwoofer. So you may not have to invest on any external sound system.
