The 58A7H is a 58 inch 4K TV from Hisense, launched in the year 2022. It features a 10-bit IPS panel with Anti-glare/Matte finish. The maximum resolution it can display is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 76 ppi.
Picture Quality
Now, the next important feature of a display that defines picture quality is Color Gamut.
This TV is rated with a DCI P3 coverage of 90%. FYI, this is equivalent to 122.73% sRGB coverage. The color quality on this TV should be Lifelike!
Understanding the Color Gamut Specification
Color gamut spec of a TV indicates the range of colors that the TV can produce.
In layman terms, it determines 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), thus producing a "washed out" picture.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 Adobe RGB, rec.2020. It is upto the manufacturer which one they choose.
As for this TV it is specified in 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.
Now, after color gamut, you should look at the static contrast specification as it impacts the picture quality substantially.
What is Static Contrast ?
The static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (<1000:1) will not produce deep blacks. Also, such TVs are likely to suffer from backlight bleeds such as below:

Clearly this will rob your experience considerably, especially in a dark room.
Note that, 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.
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 backlight technology which is a plus.
Dolby Vision, HDR10, HLG (Hybrid Log Gamma) and HDR10+ are also supported on this TV.
As for brightness, the peak luminance it can achieve is 350 nits. The backlight of this TV is powered by Direct LED technology.
Gaming Performance
Now if you are planning to use a TV other than watching videos — like as a PC monitor or for gaming purposes, make sure to get a TV that features the lowest input lag. For gaming, both input lag and response time impacts the performance.
The input lag on this TV 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 gameslike CSGO.
Understanding Input lag and response time
This lag is the latency at which your key-presses/mouse movements changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, get a TV that comes with an input lag and response time of < 20ms.
Ergonomics and Dimensions
Now, speaking of ergonomics — a VESA mount with interface size of 400 x 200 mm is provided for wall-mounting. The unit doesn't come with either Swivel, Tilt or Pivot support.
Vertically, the TV measures 58 inches and horizontally 50.83 inches.
Speaking of thickness, it is 3 inches thick. It weighs approximately 17.5 Kgs. So plan your space accordingly.
