That's only true at 8 bits per channel though, which is not what this monitor is. Otherwise yes, you're right

It's not commonly found on monitors. DSC is included starting with DisplayPort 1.4, and a good portion of monitors even today still ship with DP 1.2

Nvidia and AMD have not been shipping DSC with HDMI simply because HDMI included DSC starting with HDMI 2.1, which only the current generation of graphic cards and very few monitors support.

DisplayPort 1.2 cannot even do 5k at 60Hz at 10 bits per channel. You might be thinking about DisplayPort 2.0, which is not yet widely supported in video cards or monitors, and even then it needs the (essentially non-existent) UHBR 20 data rate to get to 120Hz.

HDMI 2.1 does support 5K@120Hz@10bpc but requires DSC as you say, which is not very commonly found either.

(Note that unlike what a sibling comment states, DSC is lossy. Some argue that the less is not noticeable to the human eye, but not everyone agrees)

I made this comment elsewhere, but all I really want is a 96x2 PPI monitor because I'm mainly on Windows and that's what widgets look their best at. 24", 3840x2560 (for 96 x 2 PPI, 3:2 aspect ratio), 120Hz, 10 bits per color, topping out bandwidth at exactly two lanes of UHBR 20 (or four lanes of UHBR10) of DisplayPort 2.0 would be my holy grail.

I could deal it being around 22" for higher density for Mac users.

It seems there's a few people in our same camp, but we haven't been heard by manufacturers yet.

A portion of that could be related to lack of protocol support. 5k at 60Hz is more bandwidth that HDMI or DisplayPort could provide until very recently. Apple got around it by essentially making it two separate displays bound together in software using a single Thunderbolt cable, but that is only really feasible when you control the entire ecosystem.

I've been waiting for basically the same thing in 3:2 or 16:10 although I'd settle for 4K, given real-world constraints. For what it's worth, that's a tremendous amount of bandwidth that even _new_ protocols such as HDMI 2.1 or DisplayPort 2.0 don't support, except DP2.0 in it's maximum bandwidth mode that hasn't been implemented anywhere as far as I know. If you take your requirements down to 4K, then both HDMI 2.1 and DisplayPort 2.0 at UHBR10 can do it.

All I really want is a 96x2 PPI monitor because I'm mainly on Windows and that's what widgets look their best at. 24", 3840x2560 (for 96 x 2 PPI, 3:2 aspect ratio), 120Hz, 10 bits per color, topping out bandwidth at exactly two lanes of UHBR 20 of DisplayPort 2.0 would be my holy grail.
