Launched in the year 2022, the XR-55A80K NA is a 55" 4K TV from Sony. It comes with a True 10-bit OLED panel.
The max. resolution it can achieve is 3840 x 2160 with a refresh rate of 120 Hz and a pixel density of 80 ppi.
After screen size and resolution, the next important spec 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 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 TV indicates the range of colors that the TV can produce.
What this means is, it indicates the ability of a display to produce accurate colors. A display with low color 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(most popular), NTSC, DCI P3 etc.
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, next in the list is Static Contrast.
What is Static Contrast ?
Static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (less than 1000:1) will not produce deep blacks. Apart from this, such TVs are likely to 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 rob your experience considerably, especially in a dark room.
Also note, 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 show both dark gray and black as black, so lesser detail overall.
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 at all.
HDR is also supported on this TV in form of Dolby Vision, HDR10 and HLG (Hybrid Log Gamma).
Coming to brightness, it is can achieve a peak luminance of 250 nits.
If you are going to use a TV other than watching videos — say as a PC monitor or Gaming, make sure to take a TV that features the lowest input lag. For gaming however, both input lag and response time impacts the performance.
The input lag on the Sony XR-55A80K NA is 5 ms and its minimum response time is 1 ms. Gamers gonna love this TV.
What is Input lag ?
This lag is the latency at which your key-presses/mouse movements changes the content of your TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, look for a TV that features an input lag and response time of less than 20ms.
Ergonomics and Dimensions
