You sure the monitor itself doesn't have any weird settings? Are both connected through DP/HDMI?

potent dragon Aug 5, 2025, 9:01 PM

#

one dp one hd

worthy vortex Aug 5, 2025, 9:02 PM

#

well, ideally both should use the same interface

#

do you have an extra hdmi/dp cable?

potent dragon Aug 5, 2025, 9:03 PM

#

wait no

#

one dp connected to pc and to the monitor its hdmi

#

and the other one hdmi hdmi

#

because my pc only have 1 hdmi port

worthy vortex Aug 5, 2025, 9:04 PM

#

#

btw i deactivated the 2nd monitor in settings because my chrome was in the right monitor so

worthy vortex Aug 5, 2025, 9:11 PM

#

this output is weird

#

try xrandr --output HDMI-0 --auto --right-of DP-5

#

this will activate and place the output at the right of your other monitor

potent dragon Aug 5, 2025, 9:13 PM

#

potent dragon Aug 5, 2025, 10:15 PM

#

worthy vortex perhaps try to restart

worthy vortex Aug 5, 2025, 10:32 PM

#

hmm.. i'm out of fixes then

#

Try the experimental wayland session

potent dragon Aug 5, 2025, 10:35 PM

#

worthy vortex Try the experimental wayland session

whats that

worthy vortex Aug 5, 2025, 10:35 PM

#

A different way of displaying stuff on your screen

#

Default is X11. Old as fuck but reliable

#

Still, the 'oldness' comes biting back with weird multi monitor setups

#

Anyways, to enter the wayland session, click on the mountain icon next to the password prompt on the login screen, select Cinnamon on wayland and log in

When I first switched to Linux a few years back I went out and bought an identical monitor to the best one I had at the time and that fixed all my issues. I had screen tearing and weird artifacting crossing over from my 1080p monitor to my 1440p monitor, it was as if the the 1440p monitor had a 1080p ghost boundary overlapping on it.

you got the same problem black screen but detected?

wintry birch Aug 6, 2025, 11:47 AM

#

I didn't @potent dragon . I had screen tearing issues where my smaller monitor's display border would appear as an artifacted ghost on the larger monitor's display. Back then I was so new to Linux Mint that I didn't even know how to open the terminal so I put nearly 0 effort into trying to fix the problem through a software solution. Nowadays I would probably spend at least a few hours trying to resolve an issue like that before turning to $ or hardware solutions.

potent dragon Aug 6, 2025, 5:22 PM

dense wasp Aug 6, 2025, 5:23 PM

potent dragon Aug 6, 2025, 5:23 PM

dense wasp Aug 6, 2025, 5:24 PM

#

If you set red one as primary, do they switch? Red one wrks, green one's black.

dense wasp Aug 6, 2025, 5:25 PM

potent dragon Aug 6, 2025, 5:26 PM

#

dense wasp Aug 6, 2025, 5:28 PM
