Is it DP output to DP input, or some mode conversion to HDMI?
I have this happen almost clockwork after a suspend awaken, reboot, even just a
glitch of the power to the dock or something, and seems to come largely from
having to use DP on dock to HDMI on TV conversion. Often I'll see the display
after reset come up instead of my Samsung TV's I use to display as generic
"NVidia 640x480", and is usually all xrandr sees as well, indicating like the
conversion chip in the cable/adapter glitches and EDID data doesn't resolve
correctly on the host. I often have to end up unplugging physically and
resetting the DP end of the cable/adapter to fix it.
With my laptop dock with only DP out, this got annoying and problematic enough
I bought specific EDID spoofers to keep this from changing any more than
needed, but still occasionally I need to reset power to those as well, even
re-seat the cable to get it back to sanity. I've never had actual DP displays
to see if this is any better, but HDMI-only displays are certainly a curse and
four-letter word.
Quite annoying using ANY sort of conversion for me between DP and HDMI. This
has been going on damn near a decade for me I've dealt with in various ways
across various devices, but it never seems to get better with adapters, video
cards, docks, or any combination of.
