The 55A9G is a 55 inch 4K TV from Hisense. It was launched in 2021. 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 next important feature of a display that defines picture quality is its Color Gamut.
Speaking of which, this TV comes with 97% DCI P3 color gamut coverage. This is equivalent to 132.27% sRGB. The color quality on this TV will be Lifelike!
Understanding Color Gamut
Color gamut spec of a TV is the measurement of the range of colors that the display can display.
A TV with poor color accuracy will produce washed out colors that will not be pretty to look at.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 Adobe RGB, rec.2020.
In case of this TV, its color gamut is specified in DCI P3.
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.
Why its important?
The static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (less than 1000:1) will not produce deep blacks. Apart from this, such displays may 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 viewing experience, especially in a dark room.
Also, 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.
For a display with OLED panel, its static constrast will be Infinity : 1. So no need to worry about this at all.
Dolby Vision, HLG (Hybrid Log Gamma), HDR10+, Dolby Vision IQ and HDR10 are also supported on this TV.
Coming to brightness, it is can achieve a peak luminance of 800 nits.This amount of brightness is good enough even for a well-lit room!
If you are planning to use your TV solely for content consumption, you can safely ignore these specifications. But if you are also going to use the TV for playing games or use it as a PC monitor, make sure to take a TV that features the lowest input lag and response time.
The input lag on the Hisense 55A9G is 20 ms and its minimum response time is 1 ms. It is acceptable 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 latency at which device inputs changes the content of the screen. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, look for a TV that features an input lag and response time of < 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 55 inches and horizontally 48.58 inches.
It is 4.29 inches thick. Overall the TV weighs approximately 30.7 kgs including stand. Without stand, it weighs 21.5 Kgs. So plan your space accordingly.
Now, 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 200 mm. The unit doesn't come with Swivel, Tilt or Pivot support.
