The 55X8F is a 55 inch 4K TV from Hisense, launched in the year 2021. It features a True 10-bit OLED panel.
It can achieve a max resolution of 3840 x 2160 with a refresh rate of 120 Hz and pixel density of 80 ppi.
Picture Quality
After screen size and resolution, the next important spec of a display that will impact your viewing experience is its Color Gamut.
This TV doesn't come with a color gamut specification, so we have to make an assumption based on its panel type.
Now, since the TV features an OLED panel, there is no need to worry about color accuracy. OLED panels are excellent at producing accurate colors.
What is Color gamut ?
Color gamut specification of a TV indicates the range of colors that the TV can show.
Meaning, this specification tells the ability of a TV to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
Different manufacturers use different measurement standards to specify color gamut. Viz — sRGB (most popular), NTSC, DCI P3 to name a few.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, the static contrast ratio of a TV has equally important role in picture quality.
What is Static Contrast ratio ?
A TV with low static contrast ratio will not produce deep enough blacks and may bleed backlight as shown in the images below:
The image is an example of another display, it is not this oneThe static contrast ratio of above TV is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More the better.
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, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
For a display with OLED panel, its static constrast will be Infinity : 1. So no need to worry about this.
HDR is also supported on this TV in form of HDR10, HLG (Hybrid Log Gamma) and Dolby Vision.
As for brightness, it is capable of producing a peak brightness of 250 nits.
Gaming Performance
Now if you are planning to use the TV other than using it as a TV — like as a PC monitor or Gaming, make sure to get a TV with lowest input lag. For gaming however, both the input lag and response time impacts the performance.
The input lag on the Hisense 55X8F is 5 ms and its minimum response time is 1 ms. Pick this one if you are a gamer.
What is Input Lag and Why it matters ?
This lag is the amount of time at which 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.
Although for better experience, get a TV that has an input lag and response time of < 20ms.
