I have a late 2008 MBP. I connect it to my Sony 52W3000 using Apple's mini DisplayPort to DVI adaptor and a DVI to HDMI cable. When I use the Nvidia 9400M (Better Battery Life in Energy Saver system preference) I get lots of video noise in the form of little red pixels. When I switch to the 9600M (Higher Performance in Energy Saver) the image is beautiful and without noise.
Is this problem inherent with the 9400M? Is it Apple's DisplayPort -> DVI dongle? I would rather conserve battery AND have a decent video image. I'd also like to get a Mac Mini to as an HTPC but don't want the terrible noise I get from the MBP when using the 9400M. I somehow doubt it's an Nvidia problem.
