Hot take: Industry should abandon HDMI.
DisplayPort is better in every single case (licensing, bandwidth, physical connection).
Every single time I need to use HDMI, I have some kind of issue. One of my monitors is connected using HDMI and I had to add aliases to my shell called "fucking-lg-on" and "fucking-lg-off" that writes values to i2c device (DDC) to tell the monitor to suspend.
Otherwise when kscreenlocker sends DPMS standby, monitor keeps disconnecting and re-connecting itself which sooner or later crashes my wayland session.... and that's just one example.
I've had issues with HDMI as far back as I can remember (likely circa 2014 when I finally could afford swapping burnt-out CRT from 1999 with 1080p LCD monitor).
DisplayPort however? Zero, nada.
Then of course there's HDMI Forum which I personally hate with burning passion (for obvious reasons).
I genuinely wonder *why* manufacturers of monitors and TVs stick with HDMI when DP is superior in every single way.
