HDMI (nvidia 1050TI) no detect - fedora 32, fedora 33 beta about fedora-copr-kde5 HOT 6 OPEN

Don't think it can be caused by KDE updates.
It could be something wrong with new nvidia drivers or linux kernel.
Are you using nouveau or proprietary nvidia driver?

Looks like similar bug: https://bugs.kde.org/show_bug.cgi?id=362058.
Or not?

for the bug:
Indeed, it may be on the kernel/driver side but without certainty, since several updates have arrived at the same time (kde/plasma, driver, kernel)

from fedora-copr-kde5.

Just FYI
My guess is the nVidia driver as I have no such issue on this box using HDMI

Kernel Version: 5.8.14-200.fc32.x86_64
Drivers from negativo17 450.80.02
Graphics Processor: GeForce GTX 650/PCIe/SSE2

Sorry, can't say anything useful about NVidia mobile GPU's, I don't have such devices at home or at work.
Better create issue on the Red Hat Bugzilla (https://bugzilla.redhat.com) or ask a question on the Ask Fedora (https://ask.fedoraproject.org/).

The problem has disappeared, the hdmi port is functional again, as it appeared without explanation.

Since yesterday, I just typed some commands such as: xrandr -q, xrandr --output HDMI --pos 1920x0 --mode 1980-1024 --rate 60, ... Restarted with no results.

However, this morning, after a shutdown of the PC yesterday, I relaunch it today and it works.

Mystery!!!
