Hey all,
I require some assistance on a Viewsonic monitor VP181 that keeps showing no signal when accessing pc in the morning.
System:
Dell Optiplex GX100, 600 mhz PIII
Win2k Pro
Nvidia TNT2 model64 pro
Basically one of our higher ups logs of her pc at night, leaving it on as others do without issue. When she comes in the morning and bumps mouse or tap keyboard, monitor light turns green for about a second and displays "no signal" as if the vid cable is loose. Check cable, fine, hit power button on/off no change. Inorder to get signal you must reboot pc, then all is well. We have swapped out vid card, monitor, reset power management in the os (except for bios, going to check that next)We will also check the hibernation tab also, but it has us baffled and we know its got to be something silly that's been overlooked or maybe a profile issue that hasnt taken in effect?. Humbly request ideas, thx people.

Hi there,
Are you using the original video cable???
We had the same problem, when we where using the cable from the CRT monior for an LCD display...
HOPE THIS HELPS

Yes we used the original cables that came with the monitors (flat screen) including swapping them out, with no change, thx though.

Thx for the replys, apparently it was the virus update that runs at night that was causing the pc to hang. Since you guys gave some issues that I checked I'll award points anyway.

Had the EXACT same problem at our office with a new NEC LCD display.
The PC was hibernating and the NO Signal would show "another reason I hate LCD's". Changed the power management setting in the BIOS and all is well. Look into your BIOS settings, as you said, it is probably just some silly little oversight.

Good luck
