I only get 640x480@60hz resolution using a Display Port to HDMI cable, on every port, monitor and tv, I can’t seem to force another resolution on both wayland and x11
Windows works as expected with every monitor and tv, and using a DP to DVI cable works as expected on all monitors on linux.
- Is this a known issue that is fixable?
- Is this specific cable the problem? Should I get another DP to HDMI cable?
- Is this a “DP to HDMI” cable problem? should I get another DP to DVI cable?
this is the cable
I have both Wayland and x11, and KDE plasma
My GPU has 3 DP inputs and 1 HDMI input
I have 3 1080p monitors with vga/dvi/hdmi inputs and one 4k tv with hdmi only
OS: Manjaro Linux x86_64
DE: Plasma 5.27.10
CPU: AMD Ryzen 9 7950X (32) @ 4.500GHz
GPU: AMD ATI Radeon RX 7900 XT/7900 XTX
All my monitors use a DP to DVI cable, and my TV uses the regular HDMI cable, I borke one of the DP to DVI cables so I decided to replace it with a DP to HDMI cable
to my suprise, it didn’t detect any resolution no mather what port I connected it to, or what monitor or tv I used, it always detects the monitor as 640x480 only. On windows I have no problems.
Since my TV is 4k, only wayland handles scaling correctly, so it would be very anoying if I have to use x11 to force another resolution.
Maybe someone can suggest another dp to hdmi cable that does work, I would like to avoid having to buy a DP to DVI cable that may be obsolete if I replace a monitor.
