HDMI monitor turns off and doesn't turn on again

Hello everyone,

I have a Lenovo X1 Extreme to which i connect 2 Samsung G5 Odyssey monitors. One of them is connected HDMI->HDMI and the other is connected USB->HDMI.

When i boot, both screens are on and they both work as expected. However, leaving the laptop for a while makes the HDMI->HDMI monitor turn off and waking up the laptop doesn't bring back the monitor's display. I have made sure to turn off DPMS, where:

xset -q

xrandr seems to recognize all 3 monitors (including the laptop's one):

xrandr --listmonitors
Monitors: 3
 0: +DP-2 1920/344x1080/193+5120+0  DP-2

 2: +HDMI-0 2560/597x1440/336+0+0  HDMI-0

I don't have any xorg.conf files but i have this in my /etc/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf

Section "OutputClass"
    Identifier "intel"
    MatchDriver "i915"
    Driver "modesetting"

I have tried switching source on the HDMI monitor itself to no avail, also tried disconnecting the HDMI cable and reconnecting it and replacing it with a different cable but the issue is still there.

As i type this post, xrandr shows the following:

But the HDMI monitor isn't displaying anything.

For the record, i have disabled `tlp` as well so that i know for sure that it's not the power saving daemon that is switching off the monitor. The other monitor connected USB-C->HDMI is always on without any issues.

How can i resolve this issue?
