What is 10 bpc color? I am a Low end user. So, Please tell me

Imagine a gradient bar of red, green, or blue on a display. The latest displays show so many colors that the 256 shades in an 8-bits channel will show banding.

Banding is horrible for photo/video editing hence 10 bit displays that can show 1024 shades in a single channel which is more shades than our eyes can see.

HDR in gaming also uses 10-bit per channel, but it's often a gimmick with current cheap gaming displays and might show banding even if there are technically 10-bits. OLED gaming monitors should be able to display 10-bit accurately though.

Thanks for explanation

It's useless if you don't play games. 10-bit color depth. Most monitors and graphics cards support only 8-bit (per color). But high end ones, yeah, they do support 10-bit (HDR monitors).

The meme is not mine, stole it, but I did find it funny, even though I don't play games.

EDIT: Whenever you see a meme from me, just presume it was stolen, lol. I rarely make my own.

That one was already clear when you wrote "It’s useless if you don’t play games." Actual media artists wouldn't say that about higher color depth.

PS: Professional media production uses 16bits per color channel: https://en.wikipedia.org/wiki/Color_depth#48-bit

Most monitors and graphics cards support only 8-bit (per color).

Plenty of monitors support 10 bit colour. You need higher than 8 bit for any colour spaces larger than sRGB, such as DCI-P3 or Adobe RGB, and most good monitors support higher than 100% sRGB coverage.

Out of all the colours that humans can perceive, sRGB covers around 35% of them, DCI-P3 covers around 52%, and Rec 2020 (which is 11 or 12 bit) covers around 75%. Colours look more vibrant when using DCI-P3 or Rec 2020 because there's literally more colours available.

Probably useless 10bits depth per color?
