Vista - Dual screen second monitor sometimes doesn’t come on after S3 wake.

I think after this update:
Update for Windows Vista for x64-based Systems (KB968389)

…my dual monitor video card:
PNY VCG86GTS5XWB-OC GeForce 8600 GTS 512MB 128-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card

…sometimes does not bring the second monitor on after waking from S3 sleep.

It’s still in dual screen mode as I can see a taskbar window fly to the second monitor. But I have to sleep and wake again to get it to come back on.

Anyone else experience something like this? I don’t remember it ever happening before and was wondering if it could be the patch.

according to micrsoft its an XP patch

anyhoo it could be a driver issue , you could reinstall your gpu driver or better still update it to the latest

Tried that. It didn't work.

I personally dont have any problems with it, but my pc also doesn't have sleep mode enabled, it shuts off the monitor after 20 mins but everything else stays power'd up. Try disabling sleep mode and see if its waking it up from power off monitor correctly.

I have that in addition to S3 sleep mode. It only has that probelm comming out of sleep mode. It doesn't always occur. Just sometimes. It never happened a few weeks ago.

Well, I found the problem. The Windows Update was just a cooincidence and didn't seem to have anything to do with it.

My monitor now wouldn't even come on at all.

I switched the cables but it didn't show anything on the bad monitor.
I was able to get display 2 on the good monitor while the bad monitor showed nothing.
It still makes the "new device sound" when I attach the bad monitor...but it doesn't show anything.
I replugged power and it still didn't do anything.

One interesting thing to note was that the good monitor's LED on standby blinks at about 2x the rate as the bad monitor. I'm sure they used to blink the same. Is this like a "service indicator" or something, perhaps?

Any ideas? Should I kick it? I'm not sure these LCD's can take what CRT's can when the screen goes out! LOL!

Man, this sucks. It's such a pain just using one monitor after having used 2 for a while.

Conclusion:

FYI, I sent it in to Samsung. Pretty fast service.

The symtom was called "Dark Video".

It looks like they changed the "Condenser" (BN81-02021A).
