ABOUT THIS TV

Sony XR-77A80K 400x400 Image Sony XR-77A80K

The XR-77A80K is a 77 inch 4K TV from Sony. It was launched in 2022. It comes with a True 10-bit OLED panel.

It can display a max resolution of 3840 x 2160 with a refresh rate of 120 Hz and pixel density of 57 ppi.

Picture Quality

After screen size and resolution, the very next feature of a display that will impact your viewing experience is its Color Gamut.

This TV doesn't provide a color gamut specification, but don't worry, we have other means to guess that.

As the TV features an OLED panel, so we can conclude that the equivalent sRGB coverage of this panel would be far above 100%.

Understanding the Color Gamut Specification

Color gamut spec of a TV is a measure of the range of colors that the TV can produce.

A display with poor color accuracy will produce undersaturated colors that will not be pretty to look at.

Different manufacturers use different units to define color gamut. Viz — sRGB, 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.

Color Gamut Chart

Now, next in the list of important specifications that will impact your experience is Static Contrast.

What is Static Contrast ?

A TV with low static contrast ratio will not produce deep blacks and may bleed backlight as in the below image:

Backlight bleed exampleThe image is an example of another display, it is not this one

The static contrast ratio of above TV is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More is better.

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, 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.

Given this TV comes with an OLED panel, its static constrast should be 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).

Coming to brightness, it is capable of producing a peak brightness of 250 nits.

Gaming Performance

If you are planning to use a TV other than watching videos — say as a PC monitor or Gaming, you should get a TV with lowest input lag. For gaming however, both input lag and response time affects the performance.

The input lag on this TV is 5 ms and its minimum response time is 1 ms. Gamers gonna love this TV.

What is Input lag ?

This lag is the amount of time at which inputs changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.

Although for better experience, get a TV that comes with an input lag and response time of less than 20ms.

Dimensions and Ergonomics

The vertical and horizontal measurements of this TV are 67.8 inches and 40.31 inches ( adjustable upto 1.65" ) respectively. It is 2.13 inches thick. Overall it weighs around 37.0 kilograms including its stand. Without stand, it weighs 34.8 Kgs. So plan your space accordingly.

Coming to ergonomics — VESA mount is supported on this TV with an interface size of 300 x 300 mm. Swivel, Tilt or Pivot features are not supported on this unit.
