Unable to set native resolution on nvidia HDMI output
Hi everyone,
I am using a Dell U2515h with a native resolution of 2560x1440@60. On my Thinkpad connected via DisplayPort everything works fine out of the box.
On my Desktop, however, I didn't manage to set the resolution by any means. The Desktop computer is connected via HDMI on the following graphics card.
lspci | grep -i nvidia
<br> 01:00.0 VGA compatible controller: NVIDIA Corporation GF110 [GeForce GTX 560 Ti 448 Cores] (rev a1)
I know there is some issue with the combination of the graphics card, hdmi connection and the monitor. Somehow the edid information can not be read properly. On windows I was able to just set a custom resolution and everything worked fine.
On fedora, i haven't yet managed to resolve the issue. I found a lot of guides, but none worked for me.
The following one is trying to use xrandr to use a ModeLine Entry:

This gives me the following error:
[root@linux ~]# xrandr --addmode HDMI-0 "2560x1440R"
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 139 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 31
Current serial number in output stream: 32
I have also already exported EDID information on the Thinkpad and tried to use it on the Desktop, but still no success.
Any ideas what else to try to solve this issue?
