Hi @all, I have problems to set the resulution for my externel LCD-Screen. It works fine until I came back from my holiday and did some updates.
I like to use 1440x900 but I can't choose it in the Nvidia-settings. I tried some changes in the xorg.conf without success.
It's interresting that I get the message "The EDID for SAMSUNG (DFP-1) contradicts itself" in the Xorg.0.log?
