Launched in the year 2021, the 48X8F is a 48" 4K TV from Hisense. It comes with a True 10-bit OLED panel. The max. resolution it can achieve is 3840 x 2160 @ 120 Hz with a pixel density of 92 ppi.
Picture Quality
After screen size and resolution, the next most important spec of a display is its Color Reproduction Accuracy (defined by its color gamut specification).
Hisense did not provide a color gamut rating for this TV. So we have to take a guess.
Since the TV comes with an OLED panel, there is no need to worry about color accuracy. Because OLED panels ALWAYS come with over 100% sRGB coverage.
Understanding the Color Gamut Specification
Color gamut spec of a display indicates the range of colors that the TV can show.
In other words, this specification tells the ability of a TV to produce accurate colors. A display with low gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
Different manufacturers use different units to define color gamut. Such as — sRGB (most popular), NTSC 1953, DCI P3 Adobe RGB and rec.2020.
But you don't need to worry about that, below is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, the static contrast specification of a TV has equally important role in picture quality.
Understanding the static contrast ratio of a TV
A TV with low static contrast ratio will not produce deep blacks and possibly can bleed backlight as in the below image:
The image is an example of another display, it is not this oneThe above TV's static contrast is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More the better.
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.
Given this TV comes with an OLED panel, its static constrast should be Infinity : 1. So no need to worry about this at all.
HDR is also supported on this TV in form of HDR10, HLG (Hybrid Log Gamma) and Dolby Vision.
As for brightness, it is can produce a maximum brightness of 250 nits.
Gaming Performance
If you are planning to use your TV solely for content consumption, you can ignore these specifications. But if you are also going 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.
The input lag on the Hisense 48X8F is 5 ms and its minimum response time is 1 ms. You will love this TV if you are a gamer.
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 screen. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, look for a TV that comes with an input lag and response time of less than 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 48 inches and horizontally 42 inches. In terms of thickness, it is just 2.6 inches thick.
Overall this TV weighs 15.6 kgs (including stand). Without stand, it weighs 14.8 KGs. So plan your space accordingly.
Now, speaking of ergonomics — VESA mount is supported on this TV with an interface size of 300 x 300 mm. There is no Swivel, Tilt or Pivot feature support in this TV.
