Hi Daniel, Thanks for the help and the quick response.
I don't see any marking on the HDMI cable I'm using so I'm guessing it isn't one a high quality one. So, I played around with the refresh rates and got it to work at a lower refresh rate: xrandr --addmode HDMI-2 2560x1440_24.00 xrandr --output HDMI-2 --mode 2560x1440_24.00 xrandr --newmode "2560x1440_24.00" 113.75 2560 2648 2904 3248 1440 1443 1448 1463 -hsync +vsync This ties in with the poor quality cable idea. Thanks again for the assistance, Jerry. On Wed, Dec 15, 2021 at 3:00 AM Daniel van Vugt <1901...@bugs.launchpad.net> wrote: > I'm guessing a common cause of this bug is low quality HDMI cables.
