The 55U7G AU is a 55 inch 4K TV from Hisense, launched in the year 2021. It features a 10-bit VA panel with Anti-glare/Matte finish. The max. resolution it can display is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 80 ppi.
After screen size and resolution, the next important feature of a display that impacts picture quality is Color Gamut.
Hisense did not provide a color gamut specification for this TV. But don't worry, we have other means to guess that.
Now, since the TV features a 55 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 quality on this TV will be Lifelike! Meaning it is capable of producing accurate colors by default.
Understanding Color Gamut
Color gamut specification of a TV indicates the range of colors that the display can display.
A TV with poor color accuracy will produce undersaturated colors that will not be pretty to look at.
Different manufacturers use different measurement standards to define color gamut. Such as — sRGB (standard RGB), NTSC 1953, DCI P3 etc.
But you don't need to worry about that, below is a chart that you can use to choose a TV with good color accuracy.
After color gamut, the static contrast specification of a TV has equally important role in picture quality.
Understanding the static contrast ratio
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.
Static contrast specification tells the intensity of black levels. That is, a TV with SC ratio less than 1000:1 will produce black images something like this:
Apart from that, such TVs may suffer from backlight bleeds that will rob your experience — as shown below.The image is an example of another display, it is not this one
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, thus 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 8000:1., good enough to achieve deep blacks. For the record, it also comes with local dimming backlight which is a plus.
HDR is also supported on this TV in form of Dolby Vision, HDR10 and HLG (Hybrid Log Gamma).
Coming to brightness, it can go as bright as 250 nits. The backlight used on the panel is Direct LED (Full-Array Local Dimming).
If you are planning to use your TV only for content consumption, you can ignore these specs. But if you are also planning to use the TV for playing games or use it as a PC monitor, make sure to take a TV that features the lowest input lag and response time.
Sadly, Hisense did not specify the input lag on this unit. Now, as this is not a cheap TV, input lag on this TV could be 20ms or below.
What is Input lag ?
This lag is the amount of time at which your device inputs changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, get a TV that has an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The vertical and horizontal measurements of this TV are 48.31 inches and 30.75 inches respectively.
It is just 3 inches thick.
In total it weighs 15.0 KGs (including stand). Without stand, it weighs 14.7 kgs. So plan your space accordingly.
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 300 x 200 mm. Swivel, Tilt or Pivot features are not supported on this unit.
Hardware and Audio
The TV comes with a 4-Core (2x ARM Cortex-A73 + 2x ARM Cortex-A52) CPU along with a (ARM Mali-G51) GPU.. There is no data about the available RAM on the TV's official specsheet.
The Operating System on this TV is VIDAA U5.0.
For display connectivity, there are four HDMI 2.0 (CEC) ports and one AV Composite In (Video + L/R) port on this TV.
To connect USB devices, you have — 1x USB 2.0 and 1x USB 3.0. Other connectivity ports include — 1x Cable/Antenna In (F-type female) and 1x Ethernet RJ45.
For connecting to this TV wirelessly, the manufacturer has provided Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct and Bluetooth 5.0.
The Audio unit of this TV is powered by 2 x 10W built-in speakers.
In terms of power consumption, on average, it uses about 113.28W. On standby, it takes 0.5 W.
For powering this unit, you will require an 100 V - 120 V/50 Hz - 60 Hz outlet.
