The 70A6G is a 70 inch 4K TV from Hisense. It was launched in 2021. It comes with a 10-bit VA panel. The maximum resolution it can display is 3840 x 2160 @ 60 Hz with a pixel density of 63 ppi.
Picture Quality
After screen size and resolution, the very next feature of a display that will impact your viewing experience is its Color Gamut.
This TV doesn't come with a color gamut specification, but don't worry, we have other means to guess that.
Considering the TV features amassive 70 inch screen, it won't come with a cheap panel, so here we can assume its equivalent sRGB coverage to be 90-100% or above. The color accuracy on this TV will be Lifelike! Meaning it will produce color accurate images.
Understanding the Color Gamut Specification
Color gamut spec of a display is the measurement of the range of colors that the display can display.
In other words, this specification indicates the ability of a display to produce accurate colors. A TV with low 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.
But don't worry, below 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 has equally important role in picture quality.
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. Moreover, such TVs are likely to suffer from backlight bleeds such as below:

Obviously this will rob your viewing experience, especially in a dark room.
Also, 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, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
We couldn't find a static contrast ratio specification for this TV. So we have to make an assumptionagain. The static contrast ratio of this TV would be surely atleast 3000:1. the static contrast ratios of VA panels range between 3000:1 - 8000:1.
Dolby Vision, HDR10 and HLG (Hybrid Log Gamma) are also supported on this TV, so that's a plus.
As for brightness, it can go as bright as 250 nits. The backlight of this TV is powered by Direct LED technology.
Gaming Performance
If you aren't into gaming, you can safely ignore these specifications. But if you are also planning to use the TV for playing games or use it as a PC monitor, you would want to get a TV that features the lowest input lag and response time.
Unfortunately, Hisense did not specify the input lag on this unit. Now, 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/mouse movements changes the content of the screen. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, get a TV that features an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 400 x 300 mm. There is no Swivel, Tilt or Pivot feature support on this TV.
The vertical and horizontal measurements of this TV are 62.1 inches and 37.9 inches respectively.
It is just 3.3 inches thick. It weighs approximately 17.9 kilograms, another 3.1 kgs including stand. So plan your space accordingly.

For display connectivity, there are four HDMI 2.0 (b; ARC; CEC) ports and one AV Composite In (Video + L/R) port on this TV.
For connecting USB devices, it includes two USB 2.0 ports. Other connectivity ports include — 1x Cable/Antenna In (F-type) and 1x Ethernet RJ45.
For wireless connectivity, you will have — a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct and Bluetooth.
