Windows 7: Connecting 2nd Monitor turns both off

13 Sep 2012   #1

Windows 7 Ultimate 64bit SP1
Connecting 2nd Monitor turns both off

Until recently I had a LG Flatron E2351 connected via HDMI, and a LG 192WS connected via VGA (DVI adapter) to my GTX560, always worked fine, then I sold the LG192WS.

My tv is an older flatscreen model (no HDMI), but has a VGA connector (this has worked before being connected), but the other day I went to reconnected the TV to the PC, and I get no signal on the TV, and the monitor goes into sleep mode, I have to reboot (removing the tv cable does nothing) to one monitor (HDMI). If both monitor & TV are connected at startup the pc won't boot until VGA cable removed.

Any ideas?
