The 55A7H is a 55 inch 4K TV from Hisense, launched in the year 2022. It features a 10-bit IPS panel with Anti-glare/Matte finish.
It can achieve a maximum resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 80 ppi.
After screen size and resolution, the next most important spec to look for in a display is its Color Reproduction, which is defined by its color gamut specification.
This TV comes with a DCI P3 color space coverage of 90% — equivalent to 122.73% sRGB. The color quality 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 the TV can display.
Put Simply, it 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), so the image produced will look "washed out" in colors.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 etc. It is upto the manufacturer which one they choose.
In case of this TV, its color gamut is specified using DCI P3.
But don't worry, here is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, the static contrast ratio of a TV holds almost equal role in picture quality.
Understanding the static contrast specification
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 TVs are likely to suffer from backlight bleeds such as below:The image is an example of another display, it is not this one
Needless to say, this will affect your experience, especially in a dark room.
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 produce less shades of colors, thus lesser detail overall.
This TV features a static contrast ratio of 1200 : 1. — good enough for a TV in this range. For the record, it also comes with local dimming which is a plus.
Dolby Vision, HDR10, HLG (Hybrid Log Gamma) and HDR10+ are also supported on this TV.
Coming to brightness, it can go as bright as 350 nits with the help of Direct LED backlight.
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 playing games 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 55A7H is 20 ms and its minimum response time is N/A. It is good enough for casual and non-FPS games but is not suitable for competitive or FPS games like COD.
What is Input Lag and Why it matters ?
This lag is the latency at which your key-presses/mouse movements changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, get a TV that features an input lag and response time of less than 20ms.
