Hi,
My HDMI to TV (Samsung) stopped working 2 days ago and I'm trying to find out
how to test the port. This is a Fedora 33 (Rawhide) (x86_64) system. The cable
is good... swapped with a known working cable. Directional 15' Saphire
cables... have arrows and are pointing the right direction (away from the
system, to the TV).
Any hints/tips/suggestions would be beyond GREATLY appreciated.
what means "stopped working" ?
AFAIK, "known working cable" is relative:
Got two boxes, both "working" with HDMI.
but exchanging the cables => one box: NO picture ...(sometimes)
No idea how to test a HDMI port, just some idea's:
what has happend between the working / non-working state ?
video related updates ?
video related BIOS settings still okay ?
settings from the TV still okay (maybe a hidden FW update) ?
xrandr -q
=> HDMI yes/no ?
sound via HDMI and headphone output at the TV ?
