I have a 22'' display from HP (w2207h) connected to my laptop (a Dell Mini 10v or 1011) through a VGA switch (a share this screen with a desktop computer and a Nintendo Wii). My problem is that I can't set a higher resolution than 1024x768 (4:3) in my external display. I can only set a lower resolution (800x600 and 4:3). I used it before with Ubuntu and I had no problem with the screen resolution so I think the problem is the VGA switch. Does anybody knows how to fix this problem? Does anybody knows how I can start?
This is a screenshot of my screen configuration. The green one is the HP display and the word you can read on it is "unknown". Yes, it's in spanish. Thank you very much.
