I have a self-installed Lenovo T500 laptop. Yesterday, I tried plugging in my LG monitor and changed two things: - I extended the desktop to it so that I could see two documents side by side. - I selected the 3rd monitor in the combo box located between the picture of the screen and the resolution slider, which funnily showed no name for the display driver (so the caption was something like "Plug and Play Monitor with")
As soon as I hit 'Apply', both screens started displaying garbage, and this persists after a reboot. The screens display colors, but the picture seems chopped up in small rows that are offset so that there is no way to recognize anything.
I started XP in VGA mode, which works fine, but in the display settings dialog, I don't have the same choices as I had in normal mode, so I can't undo what I did: there's no combo box to select the display, and there's no option to extend the desktop.
How can I change this back?
I also tried disabling both Intel graphics adapters, uninstall all monitors from the hardware manager and update to the latest drivers for the graphics card, without success, the garbage persists when booting without VGA mode.
