I'm looking for someone who knows more than I do about HDTV and VGA input. I purchased a Samsung LN40A550P3FXZA in 2008. Recently, I've moved into a new house and this display is my new 'gaming' room display. I have a VGA box for the SEGA Dreamcast that worked great on the previous Vizio display, but I cannot seem to get it to work on the Samsung. It states "Mode Not Supported" when I attempt the power it on, plugged into the VGA port on the TV. I realize it's probably a resolution or refresh issue, but can anyone confirm that these two pieces of equipment are not compatible? If I can provide any more information, Ill be happy to do so. Thanks.
