Launched in the year 2022, the 75A7H is a 75" 4K TV from Hisense. It comes with a 10-bit IPS panel with Anti-glare/Matte finish.
It can achieve a max resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 59 ppi.
Now, the next important specification of a display that impacts picture quality is Color Gamut.
Speaking of which, this TV comes with 90% DCI P3 color gamut coverage — equivalent to 122.73% sRGB coverage. The color accuracy on this TV will be Lifelike!
What Color Gamut means ?
Color gamut specification of a display indicates the range of colors that the display can produce.
Meaning, it tells the ability of a display to produce accurate colors. A panel with low color gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
Different manufacturers use different units to specify color gamut. Viz — sRGB, NTSC, DCI P3 to name a few.
In case of 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.
Now, after color gamut, the static contrast of a TV also impacts its picture quality.
Understanding the static contrast ratio of a TV
The static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (less than 1000:1) will not produce deep blacks. Moreover, such TVs may suffer from backlight bleeds such as below:The image is an example of another display, it is not this one
Clearly this will affect your viewing experience, 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, 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 which is a plus.
HDR is also supported on this TV in form of Dolby Vision, Dolby Vision IQ, HDR10, HLG (Hybrid Log Gamma) and HDR10+.
As for brightness, it is can achieve a peak luminance of 350 nits. The backlight of this TV is powered by Direct LED technology.
If you are planning to use your TV solely 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 take a TV with the lowest input lag and response time.
Unfortunately, Hisense did not specify the input lag on this unit. But since this is not a cheap TV from Hisense, we can expect an input lag of less than 20ms.
What is Input Lag and Why it matters ?
This lag is the latency at which your key-presses or mouse movements 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 comes with an input lag and response time of less than 20ms.
Ergonomics and Dimensions
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. There is no Swivel, Tilt or Pivot feature support on this TV.
The width of this TV is 65.94 inches while its height is 41.18 inches. In terms of thickness, it is just 3 inches thick.
It weighs approximately 27.9 KGs, another 0.6 kgs including stand. So plan your space accordingly.
