What calibration did you use? The Pantone Huey and Spyder is very nice but we also have bizarre problems with this after virus, registry cleaners, some antivirus suites and corrupt profiles.
It's rarely a maker issue but for those that want a calibrated display I understand your need.
I just bought a new laptop. Samsung brand. It has Windows 7 Home Premium on it. I know this is a known issue with Win 7. I calibrated my monitor and saved the settings but when the computer hibernates, goes to sleep, or shuts down the display settings revert back to the factory settings. I've heard that the "Intel Common User Interface Module" aka "igfxpers.exe" is the culprit. However, most users have found that if they disable it in the startup tab of "msconfig" this solves the issue. But, this program is not listed under my startup tab. Does anyone know anything about this issue and how the heck I can find this program and get rid of it?? This is very frustrating. I just sent back a brand new HP for this exact same issue, not knowing at the time it was a Windows 7 issue. I'm about ready to send back this one too and get an Apple!
