The 55A8G is a 55 inch 4K TV from Hisense, launched in the year 2021. It comes with a True 10-bit OLED panel. The max. resolution it can achieve is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 80 ppi.
Picture Quality
After screen size and resolution, the next important spec to look for in a display is its Color Reproduction, which is defined by its color gamut specification.
This TV doesn't provide a color gamut specification, so we have to take a guess. As 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 spec of a TV is a measure of the range of colors that the display can display.
In other words, it tells the ability of a display to produce accurate colors. A TV with low color gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 etc.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
After color gamut, next in the list of important specifications is Static Contrast.
The importance of static contrast ratio
A TV with low static contrast ratio will not produce deep blacks and possibly bleed backlight as below:
The image is an example of another display, it is not this oneThe above TV's static contrast is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More the better.
Like resolution, the static contrast ratio is also equally responsible for 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.
For a display with OLED panel, its static constrast should be Infinity : 1. So no need to worry about this at all.
HLG (Hybrid Log Gamma), HDR10+, HDR10 and Dolby Vision are also supported on this TV, so that's a plus.
Coming to brightness, it is can produce a maximum brightness of 800 nits.This amount of brightness is good enough even for a well-lit room!
Gaming Performance
Now if you are planning to use a TV other than using it as a TV — say as a PC monitor or for gaming purposes, you would want to take a TV that features the lowest input lag. For gaming however, both the input lag and response time impacts the performance.
The input lag on the Hisense 55A8G is 20 ms and its minimum response time is 1 ms. It is good enough for casual and non-FPS games but is not suitable for competitive or FPS gameslike CSGO.
What is Input Lag and Why it matters ?
This lag is the amount of time at which your key-presses or mouse movements 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.
Dimensions and Ergonomics
The vertical and horizontal measurements of this TV are 48.27 inches and 30.75 inches respectively. Coming to thickness, it is just 2.68 inches thick.
Overall this TV weighs 19.0 kilograms including stand. Without stand, it weighs 18.0 kgs.
Speaking of ergonomics — VESA mount is supported on this TV with an interface size of 300 x 200 mm. Swivel, Tilt or Pivot features are not supported on this unit.
Hardware and Audio
The core of Hisense 55A8G is powered by 4-Core (2x ARM Cortex-A73 + 2x ARM Cortex-A52) CPU along with a (ARM Mali-G51) GPU.. There is no data on the total RAM on the TV's official specsheet.
Speaking of OS, the Hisense 55A8G runs VIDAA U5.0 Operating System.

For wireless connections, you will have — Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct and Bluetooth 5.0.
The Audio unit of this TV is powered by 4 x 10W built-in speakers.
Now, coming to power usage, the TV consumes 100W on average and 0.5W on standby.
For powering this unit, you'll require an 100 V - 120 V/50 Hz - 60 Hz outlet.
