The UN55BU8000 is a 55 inch 4K TV from Samsung, launched in the year 2022. It features a 10-bit VA, IPS-ADS panel. It can achieve a max resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 80 ppi.
After screen size and resolution, the next important spec to look for in a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.
This TV doesn't come with a color gamut specification, so we have to take a guess.
Now, since the TV features a big 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. Undoubtedly The color accuracy on this TV will be Lifelike! It will produce color accurate images AS IT IS intended.
What Color Gamut means ?
Color gamut spec of a TV is a measure of the range of colors that the TV can show.
In layman terms, it tells the ability of a display to produce accurate colors. A TV 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. Such as — sRGB, NTSC, DCI P3 etc.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
Other than color accuracy, you should look at the static contrast specification as it influences the picture quality substantially.
The importance of static contrast ratio
A TV with high enough static contrast ratio will produce deep blacks while a TV with low contrast ratio (<1000:1) will produce images that might look muddy as shown below.
As you see, this will impact your experience considerably.
Like resolution, the static contrast ratio is also equally responsible for 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.
This TV features a static contrast ratio of 8000:1., enough to display deep blacks. The panel comes with local dimming technology which is a plus.
HLG (Hybrid Log Gamma), HDR10+, HDR and HDR10 are also supported on this TV, so that's a plus.
As for brightness, the peak brightness the Samsung UN55BU8000 can achieve is 250 nits. The panel of this TV is powered by Edge LED backlight.
If you are planning to use your TV only for content consumption, you can safely 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 get a TV with the lowest input lag and response time.
The input lag on the Samsung UN55BU8000 is 8 ms and its minimum response time is N/A. You will love this TV if you are a gamer.
What is Input Lag and Why it matters ?
This lag is the amount of time 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.
But ideally, look for a TV that features an input lag and response time of < 20ms.
