The 75A7G is a 75 inch 4K TV from Hisense. It was launched in 2021. It features a 10-bit IPS panel. It can achieve a max resolution of 3840 x 2160 @ 60 Hz with a pixel density of 59 ppi.
Picture Quality
After screen size and resolution, the very next specification of a display that defines picture quality is its Color Gamut.
Speaking of which, this TV is rated with a 90% DCI P3 color gamut coverage. FYI, this is equivalent to 122.73% sRGB. The color accuracy on this TV will be Lifelike!
Understanding Color Gamut
Color gamut specification of a display is a measure of the range of colors that the display can produce.
A TV with poor color accuracy will produce washed out colors that will spoil the immersion.
Different manufacturers use different units to specify color gamut. Viz — sRGB, NTSC 1953, DCI P3 Adobe RGB and rec.2020.
As for this TV its color gamut 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.
Other than color accuracy, you should look at the static contrast specification as it influences the picture quality substantially.
What is Static Contrast ?
The static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (<1000:1) will not produce deep blacks. Moreover, such TVs are likely to suffer from backlight bleeds such as this:
The image is an example of another display, it is not this oneClearly this will rob your viewing experience, especially in a dark room.
Other than black levels, 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.
This TV comes 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+.
As for brightness, the peak brightness the Hisense 75A7G can produce is 350 nits. The backlight used on the panel is Direct LED (Full-Array Local Dimming).
Gaming Performance
Now if you are planning to use the TV other than watching videos — like as a PC monitor or Gaming, you should get a TV that features the lowest input lag. For gaming, both input lag and response time affects 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 games.
What is Input Lag and Why it matters ?
This lag is the latency at which your device inputs changes the content of the TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, get a TV that has an input lag and response time of < 20ms.
Ergonomics and Dimensions
Now, coming to 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 400 x 300 mm. However, there is no Swivel, Tilt or Pivot feature support in this TV.
The vertical and horizontal measurements of this TV are 65.94 inches and 41.18 inches respectively. It is just 3 inches thick. It weighs around 27.9 kilograms and 0.6 kgs extra including stand. So plan your space accordingly.
