Viewsonic VA2226w Signal Loss Problem

Hi.

I have a Viewsonic VA2226w flatscreen monitor and I am having a major problem with it. It's been driving me nuts for a few months now and I can't seem to find a solution. The card I am using with it is an ATI Radeon HD3650 512MB PCIE card. I know it is not the card because I do not have this issue if I connect a different model or brand monitor.

The problem is that if I either turn off the monitor power, try to log out to the welcome screen on Vista, or switch users, the monitor will not be able to re-acquire the signal. The signal light goes yellow and stays that way, with a no signal message. If it occurs, the only way to fix it is to blind cold boot the PC with the power switch.

As you can tell, this is a pretty major problem. I have turned off suspend and power saving in Vista with no luck. I use a DVI-I dual link cable, but it does the same thing with any cable I use. I do not have an old style VGA connector on my video card so I have to use DVI. But the monitor did the same thing when I hooked it up to my daughter's machine which does have a VGA connector.

I first thought it might have been a defective monitor so I RMAed it, but the replacement did exactly the same thing.

Any help appreciated.

I realize this subsection is supposed to be for graphics cards, but I can't find a subsection for monitor problems.

Here's what I have exactly.

AMD Phenom 9600 quad core CPU
MSI K9A2 Platinum motherboard.
4GB Micron memory
ATI Rageon HD3650 PCIE video card.
Creative Labs Soundblaster Audigy ZS sound card.
Samsung DVD-RW (SATA II)
2x Seagate 500GB SATA II hard drives
1x Maxtor 500GB SATA II Hard Drive

The monitor is a VA2226w widescreen from Viewsonic.

The dual link cable allows for extra bandwidth for higher resolutions and faster response time. It is the cable Viewsonic recommends. You can use a single link cable but they said it may slow down monitor response.

If I turn the power button on the monitor off (Like when I am about to turn in for the night), but leave the PC going (which I do because I have it rendering 3D models while I sleep.) When I turn the monitor power back on in the morning, the LED stays yellow and I get a no signal error even though the PC is still on. It's like the monitor simply can't re-acquire the signal. I end up having to force a shut down with the power button to get it to kick back in. The same thing happens if I try to log off to the welcome screen or switch users without shutting down. This is kind of a pain because I frequently have to switch to my admin account to do some things on the PC and I have to reboot twice to switch.

The first VA2226w I had did this, so I RMAed it, but the replacement does exactly the same thing. My wifes Samsung 21" does not do this and it behaves normally when hooked up to my box. My Daughter's LG also works fine on my system.

Does anybody know the solution to this? My VA2226w also does this. If I put another monitor on the same PC, that monitor turns back on and acquires the signal just fine. I'm positive it's something with the VA2226W or a setting affecting that model. My PC is a Dell E510 with a RADEON X300 SE 128MB HyperMemory. Any ideas? I'm going on a year without turning my monitor off because of this problem.

Thanks!

Mine did it with XP. It does NOT do it with Windows 7, 64 bit. My thought is that it may be a driver issue.
