Greetings,
I have NVIDIA Corporation GK208B [GeForce GT 710] (rev a1) graphics controller with primary display attached to DVI-D-1 and a secondary to HDMI port.
This configuration has been in use for many months without issue, but the other day I noticed the secondary display was blank and the display was not recognized by Sway. When (re-)attaching the HDMI cable, I get this message in Kernel log:
nouveau 0000:01:00.0: DRM: DDC responded, but no EDID for HDMI-A-1Rebooting or reinstalling mesa and mesa-vdpau packages does not solve the issue.
This is a log from a previous good boot with attached display, before the issue arose:

Jul 30 12:01:34 xxxx kernel: random: crng init doneNouveau initialization entries are identical, but in the latter there are a bunch of BAD entries followed by the EDID error.
I'm normally running linux-libre, but also tested with official kernel and the problem persists.
I tried attaching another similarly configured arch linux system to the same HDMI display and the same issue occurred. Tried with a Windows laptop and it outputs to the display, so it is not a hardware issue with the system or the display.
Appreciate any ideas.
