The 55A9H is a 55 inch 4K TV from Hisense, launched in the year 2022. It features a True 10-bit OLED panel with Anti-glare/Matte finish.
The max. resolution it can display is 3840 x 2160 with a refresh rate of 120 Hz and a pixel density of 80 ppi.
After screen size and resolution, the very next specification of a display that impacts picture quality is Color Gamut.
The Hisense 55A9H features 97% DCI P3 color gamut coverage. Incase you're wondering, this is equivalent to 132.27% sRGB. The color accuracy on this TV will be Lifelike!
What is Color gamut ?
Color gamut specification of a display is the measurement of the range of colors that it can produce.
A TV with poor color accuracy will produce washed out colors that will spoil the immersion.
Different manufacturers use different units to define color gamut. Viz — sRGB (most popular), NTSC 1953, DCI P3 etc.
For example, the color gamut of this TV is specified in terms of DCI P3.
But you don't need to worry about that, here is a chart that you can use to choose a TV with good color accuracy.
After color gamut, the static contrast of a TV also impacts its picture quality.
Why its important?
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
Static contrast defines the intensity of black levels. That is, a TV with SC ratio < 1000:1 may produce black images something like this:
Apart from that, such TVs may suffer from backlight bleeds that will rob your experience — as shown below.The image is an example of another display, it is not this one
Think of static contrast as another dimension to details — just like resolution. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, so lesser detail overall.
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 point of owning an OLED TV. So no need to worry about this at all.
HLG (Hybrid Log Gamma), HDR10+, HDR10, Dolby Vision and Dolby Vision IQ are also supported on this TV, so that's a plus.
Coming to brightness, the peak brightness the Hisense 55A9H can achieve is 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 ignore these specifications. But if you are also going to use the TV for gaming or use it as a PC monitor, make sure to take a TV with the lowest input lag and response time.
The input lag on the Hisense 55A9H is 5 ms and its minimum response time is 3 ms. For a TV, its the best you can get for gaming.
What is Input Lag and Why it matters ?
This lag is the latency at which your device inputs changes the content of your display. For casual Non-FPS games, input lag doesn't matter much.
But ideally, get a TV that has an input lag and response time of < 20ms.
Dimensions and Ergonomics
The width of this TV is 49 inches while its height is 29.46 inches. In total, it weighs approximately 17.5 Kgs.
Now, speaking of 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. It comes with Swivel feature, but there is no support for Tilt or Pivot.
