2nd monitor added but goes black after a few seconds..
I just added a 2nd monitor today to my comp, a Philips 109s. It turns on fine, displays the extended screen but after maybe 7 seconds, it goes black. If I change something within the screen res section(ie landscape to portrait), it fires back up, but goes black again in a few seconds. When the 2nd monitor is on, I can mouse over to it no probs.. The power lite always remains green (on).. Basically everything is set properly, but it just goes black again until I change a property..any ideas ?
My setup:
Win 7 Ultimate 64 bit - all updates
Main display Dell E248WFP
2nd Display Philips 109s
GTX 260 (main display DVI-DVI cable, 2nd display DVI-VGA cable) - newest drivers
Both displays set at their native resolution within the screen res section
2nd monitor to the left and "extend these displays" on.
