I have a PC running Win XP (SP 3). The display adapter is Intel G45/G43 chipset.
I recently bought a new monitor and installed it in portrait position and successfully rotated the screen 90 degrees, by navigating to the graphics card menu and choosing the option there.
Now I can't find how to get back there. The hotkeys don't work. I can't find the settings under Control Panel | Display, but maybe I'm missing something.
Where else could it be?
