why yuv is preferred over rgb?

YUV color-spaces are a more efficient coding and reduce the bandwidth more than RGB capture can. ... The most important component for YUV capture is always the luminance, or Y component. For this reason, Y should have the highest sampling rate, or the same rate as the other components.

Ultra HD TVs aren't technically "4K" since their resolution is 3,840x2,160. However, it doesn't matter. 4K is way easier to say than 2,160p or Ultra HD, and when anyone runs a survey asking about it, the vast majority of you (and us, FWIW), greatly prefer "4K." So do Google.

The Fire TV Stick 4K's main advantage over Roku is compatibility with the Dolby Vision HDR format, which might be important to you if your TV performs significantly better with DV than standard HDR. But for most people, that advantage doesn't overcome Roku's strengths.

A RAW image contains wider dynamic range and color gamut compared to a JPEG image. For highlight and shadow recovery when an image or parts of an image are underexposed or overexposed, a RAW image provides far better recovery potential compared to JPEG. Finer control and adjustment potential.

High Dynamic Range (HDR) is the latest and best thing in video right now. ... In theory, HDR gaming is very similar to HDR video. The idea is that you get better contrast and a wider range of colour and brightness, which should make the picture more realistic and immersive.

Because it is a one layer image from 0-255 whereas the RGB have three different layer image. So that is a reason we prefer grey scale image instead of RGB.

Brightness levels: QLED TVs produce more vivid and brighter colors than UHD TVs. The result of this difference is a higher contrast ratio, with the picture that is provided by the QLED TVs being sharper than that offered by UHD TVs. ... Color performance: Color performance in these two TVs is quite similar.

HDR and 4K Ultra HD HDR should not be confused with the other big TV buzzword of the era: UHD (Ultra High Definition), also known as 4K. Both HDR and UHD are meant to improve your viewing experience, but they do so in completely different ways. It's a matter of quantity and quality.

12 bit color While this is technically a 64x wider color range than even 10 bit color, a TV would have to be able to produce images bright enough to actually see the color difference between the two.

Yeah, it's still necessary in most games. Whilst the aliasing is better at 1440p, it's not removed entirely. You can certainly get away with not having AA (and in the case of performance issues, turning it off is the first place to go), but if you want the best visuals, you still need some form of it on.

Illustrious. RGBW is sort of OK if you don't care about color accuracy. OTOH if you insist on color accuracy on battery, it defeats its own purpose for existing.

Still, if it's the colors you care about, then Lifx is a better pick than Philips Hue. It produces brighter, bolder colors at every shade we tested, it boasts a better app, and it gets more out of its integrations with IFTTT and Alexa.

RGB only supports 480i signals while DVI can go all the way up to 1080p. Did you set the TV resolution correctly? VGA (RGB) has no limits it can go up to 2048x1536. RGB input can go up to 1080 easily.

It creates a more soothing feel. See Amazon's Best-Selling Streaming Devices! However, that said, some people prefer the Vivid (also called Dynamic) setting because it tends to make the picture “pop.” With Vivid, you'll find that the screen is brighter and more, well, dynamic.

By all measures, UHD delivers a higher-quality, higher-resolution image than FHD (1080p). The trade-off is that UHD costs more. If you're more concerned about your budget than resolution, FHD offers a perfectly fine viewing experience. UHD (4K) slightly elevates that experience, especially on larger screens.
