I bought a cheapo capture card a while back but the quality is pretty terrible

Is there any reason PCs can’t just receive HDMI/displayport input from other devices through the same mechanism they output it?

For that matter also is there any reason HDMI can’t be run over Ethernet? Afaik ethernet has far more bandwitth than hdmi nowadays

    I’m going to be crude here: is there any reason your bladder can’t slurp your pee back up from the toilet when you’re thirsty?

    Can you reverse your monitor to suck in light and behave like a camera?

    If you push your car backwards does it suck up CO2 and fill up the gas tank?

    Most things in life aren’t as bidirectional as we’d like. Video cards use electrical drivers to push signals down the display cables, which is completely different than using what are basically sensors to detect signals coming the other way. It would be quite expensive to design a GPU that does a good job of both, and mostly pointless.
