Since updating video drivers (NVIDIA 9500 GT) and Windows 7 service pack the other day, as well as some general mucking around, my computer has managed to start booting on a single screen only.
Once into Windows, I can go into the prefs, click 'detect' and the second monitor comes on with no problems. What could be causing it to be undetected during boot anymore?
I wouldn't mind, but the lack of detection re-arranges all of my desktop icons back onto the single screen (and in a very random way!) - which is annoying.
I have 2x LG L1952S screens, one of which gets recognised while the other is seen as a 'generic' (thats the thing I was trying to fix the other day!). One of them is plugged in via the VGA port, the other through DVI with a converter, and one (the one that doesn't come up on boot) goes through a Belkin KVM switch. The display adapter is an NVIDIA 9500 GT.
