Brand-new XPS M1730 beefy graphics laptop. Twin Nvidia GeForce 8700M graphics cards with SLI. Started it up right out of the box and anything that should be white was yellow. Also, any yellow area generally had a flickering aspect to it especially if it was a gradient to another color.
Called Dell support. connected it to external monitor. Colors perfect. No flickering. Booted from diagnostic partition. BIOS screens, diagnostic screens and Safe mode w/ networking all had PERFECT color, no flicker. So seemingly a driver issue.
At one point I walked away from the pc until the screensaver came on. When I returned and resumed work, the yellow cast was GONE! I tested it several times. I found out it changes back to normal whites after the screen goes black, like power save mode. I did notice also that any pictures - especially in a browser page looked jagged and pixellated.
I found a newer driver online at nvidia's website. After loading it, no change in the yellow problem, but it DID fix the jagged picture problems in the browser.
So now I have a PC that has normal color only after the lcd goes black in power-save mode.
Notice the picture in the upper right corner of the browser screenshot below.
Also - just realized that screen shots of the yellow color does not capture it. The screen shots don't show the color! What the heck is causing this?
