As far as I am aware,
HDMI 2.1 does support 12-bit 4K 60fps, Also it doesn't use TMDS, rather FRL. Sends upto 48Gbps
GPUs can do calculation in fp32 and from some reference, I think that it can send 16bpc (48-bit per pixel deep color) (Assuming that it is a high end Quadro GPU) (fp16 had the capability to send 12bpc 36-bit deep color, right?)
But there are monitors that don't support more than 10bpc 30-bit depth deep color
Why is that? Why do displays have limited bit-depth?
Can you give me some idea about the science behind this? Why does it cost more to produce higher bit-depth monitors?
Isn't it like, RGB pixels on the displays are emitting photons? Then how do different displays differ in terms of emitting photons?
