The 65A7G is a 65 inch 4K TV from Hisense, launched in the year 2021. It features a 10-bit IPS panel.
It can display a maximum resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 68 ppi.
Picture Quality
After screen size and resolution, the next important spec of a display is its Color Reproduction Accuracy (defined by its color gamut specification).
This TV is rated with a 90% DCI P3 color gamut coverage, which 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 display is the measurement of the range of colors that the TV can display.
A display with poor color accuracy will produce washed out colors that will not be pretty to look at.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 to name a few.
As for this TV its color gamut is specified in DCI P3.
But don't worry, here 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.
Understanding the static contrast ratio
There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.
This tells the intensity of black levels. That is, a TV with SC ratio less than 1000:1 may produce black images something like this:

Apart from this, such TVs are likely to suffer from backlight bleeds that will affect your experience — as shown below.

Also note, 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, so 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.
This TV is rated with a static contrast ratio of 1200 : 1. — good enough for a TV in this range. The panel comes with local dimming backlight technology which is a plus.
HDR is also supported on this TV in form of Dolby Vision, HDR10, HLG (Hybrid Log Gamma) and HDR10+.
Coming to brightness, the peak brightness it can produce is 350 nits, powered by Direct LED (Full-Array Local Dimming) backlight technology.
Gaming Performance
If you are planning to use your TV just for content consumption, you can safely ignore these specs. But if you are also planning to use the TV for gaming or use it as a PC monitor, you would want to get a TV with the lowest input lag and response time.
The input lag on the Hisense 65A7G 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 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.
For best of both worlds, look for a TV that comes with an input lag and response time of < 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 65 inches and horizontally 57 inches.
Speaking of thickness, it is 3 inches thick.
It weighs approximately 18.5 kgs and an additional 0.6 kgs including stand. So plan your space accordingly.
Now, speaking of ergonomics — a VESA mount with interface size of 400 x 200 mm is provided for wall-mounting. Swivel, Tilt or Pivot features are not supported on this unit.
Hardware and Audio
The Hisense 65A7G comes with a 4-Core (2x ARM Cortex-A73 + 2x ARM Cortex-A52) CPU while its graphics engine is handled by a (ARM Mali-G51) GPU.. There is no mention on the total RAM on the TV's specsheet.
The Operating System on this TV is VIDAA U5.0.

For connecting to this TV wirelessly, you will have — a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct and Bluetooth 5.0.
The Audio unit of this TV is powered by 2 x 10W built-in speakers.
Now, coming to power consumption, the TV consumes 125 watts on average and 0.5 watts on standby.
For powering this unit, you will need an 100 V - 120 V/50 Hz - 60 Hz outlet.
