The 55A7200G is a 55 inch 4K TV from Hisense. It was launched in 2021. It comes with a 10-bit IPS panel.
The maximum resolution it can achieve is 3840 x 2160 @ 60 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 Color Gamut.
This TV doesn't provide a color gamut specification, so we have to make an assumption based on its panel type.
Now, since the TV features a big 55 inch screen, it won't come with a cheap panel, so here we can assume its equivalent sRGB coverage to be 90-100% or above. Undoubtedly The color quality on this TV should be Lifelike! It is capable of producing accurate colors out of the box.
What Color Gamut means ?
Color gamut spec of a TV is a measure of the range of colors that the TV can display.
In other words, this specification tells 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), the result would be a "washed out" picture quality.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 etc.
But you don't need to worry about that, below is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, the static contrast of a TV also impacts its picture quality.
The importance of static contrast ratio
A TV with high enough static contrast ratio will produce natural deep blacks while a TV with low contrast ratio (<1000:1) will produce images that will look muddy as shown in below image.
As you see, this will rob your experience considerably.
Also, a TV with high constrast ratio lets you to see more details. So, resolution and static contrast ratio go hand in hand.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
Hisense did not share the static contrast specification for this TV. Once again we have to take a guess based on the TV's other specifications. In general, IPS panels come with a static contrast ratio between 700:1 - 1500:1. Considering its a 4K TV, we can imagine the ratio of Hisense 55A7200G would be 1200:1 or above.
HDR is also supported on this TV in form of HDR10 and HLG (Hybrid Log Gamma).
As for brightness, it can go as bright as 250 nits. The backlight used on the panel is Direct LED.
If you are planning to use your TV just for content consumption, you can safely ignore these specs. But if you are also going to use the TV for gaming or use it as a PC monitor, you would want to take a TV with the lowest input lag and response time.
Sadly, Hisense did not specify the input lag on this unit. But as this is not a cheap TV, we can expect an input lag of less than 20ms.
What is Input Lag and Why it matters ?
This lag is the amount of time at which your device inputs changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, look for a TV that features an input lag and response time of < 20ms.
Dimensions and Ergonomics
The TV measures 55 inches vertically and 48.9 inches horizontally.
It is just 3.19 inches thick.
It weighs approximately 12.5 kilograms and 0.5 kgs extra if you include stand.
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 200 x 200 mm. The unit doesn't come with Swivel, Tilt or Pivot support.
