hello everybody, i have a sapphire radeon 560 that is working in all televisions at home except mine, where i can only select 640x480 as resolution

using xrandr tells me only 640x480 is supported althought my tv should be 1440x900, and althought my old geforce 530 was perfectly working

any ideas?

for the record i’m on fedora 34 with gnome…

Are you using GNOME on Wayland or GNOME on Xorg? In the former case, xrandr doesn’t work as expected. It’s probably a case of the kernel driver not detecting the display correctly, so we would need your dmesg.

hello thanks for your answer, unfortunately i ended up selling the card…

most probably anyway my very old display wasn’t supporting the higher resolutions the card could offer…
