Dimbulb

This will probably get moved but I thought one of the Windows 7 gurus might be able to correct an issue I'm having on my new DAW running Windows 7 home premium (built by our own Jim Roseberry).  Whenever I return to the desktop from running an app, checking email, surfing the net, etc... the Desktop will slowly and slightly dim after no more than five or six seconds.  This dimming seems to occur ONLY on the Desktop and only upon power up or a return from some other app or page.  Jim and I went through all the Power and Display settings...I even tried the ACU settings.  I called my monitor maker and they had no clue.  Any other ideas on how to stop this will be greatly appreciated.
 
 

Maybe do do with Secure Desktop?

Again, a stab in the dark....

Monitor color profile settings will do this.
I have messed around with mine a bunch of times (ambient light and display light)...
I have an Adobe app that changes it, but monitor manufacturers have them too.

What video card do you have?

Hi My Ol Pal,  
 
The problem isn't the build... or the video card.
We have scores of other clients (using the same machine) not having the issue.
 
I chased down the driver for your monitor.
I'd start by getting that installed.  (shoot me an Email and I'll respond with a download link)
 
Next, I'd do a factory reset on the Monitor.
 
Then, I'd go into the Nvidia Control Panel... and go to Display>Adjust desktop color settings
Under option 2, switch to "Use Nvidia Settings"  (adjust screen to taste)
 
If that fails to resolve the issue, connect via VGA.  Do you experience the same dimming behavior when connected via VGA?
It's possible that the video card is defective... but symptoms would typically be a blanketly overly dim display.
The fact that the display dims when closing apps/etc suggests a PM or display management issue.
If the video card is defective, we'll certainly replace it.
 
FWIW, This is why I like to do that follow-up call...  
Give me a call when you're free

Maybe some app installed a service that is messing with video card?

 
Hi Mike,
 
Dimming the laptop's display is a normal power-saving feature.
I'd check your current power options.  As a test, switch to High Performance mode... and disable all management options or anything that would be managed in the background (under Change Advanced Power Settings).
