Re: Display failures after running x server some time on Geforce 8300
after months I finally found the solution: The picture on the HDMI output was not scaled correctly and the TV screen (SAMSUNG) was not in PC mode.
I've found out, that the problem also occured on Windows and only on the HDMI output. So I searched all the forums out there and finally found out that the scaling was not set correctly. Unfortunately I cannot tell the correct name of the parameter because I already changed the graphic card due to a wrong assumption.
Moreover to address the problem the Samsung TV has to be configured to PC mode by naming the input slot PC.
If you ever have problems on the HDMI output like this, check the scaling of the monitor.
Sorry to bother you here.
