I bought an acer Aspire 5742Z laptop (with a Intel HD 128 MB GFX card) back in May 2011 and I think I'm starting to see a problem with the screen. I first noticed it last night and again this morning. Intermittently the screen seems to lose saturation, that is the picture seems greyer/more washed out than normal. It comes and goes lasting for only ten or so seconds at a time.
Is anyone aware of any issues with the model laptop or the graphics card that might cause this?
Update I've just checked the Windows Update history and a new driver was installed on the 14/12/2011. I've rolled this driver back to see if that has any effect.
