Description
I changed out my monitor with one that has a higher resolution. When I try to change the resolution now using the control panel, it doesn't change the output resolution. When the resolution is bigger, parts of the screen just get cut off, if it is smaller it repeats the screen in the horizonal axis and shows some garbled stuff at the bottom in the y axis. The refresh rate is fixed at 60 Hz, I can however still change the bit depth. Using the VESA driver I can change the resolution and when rebooting it does keep the resolution and shows everything fine in that resolution. The mode switch did work fine using the old monitor
The last things I did before saving the syslog were setting to a lower resolution (1024x768), setting to a higher resolution (1680x1050) and changing the refresh rate down from 85 Hz to 60 Hz. Switching the resolution changed the drawn area, but not the produced video signal, changing the refresh rate didn't do anything.
