Hello, my son was owning the big screen with an HDMI connection to his xbox 360 elite. I tried to move it to a smaller Acer monitor with a VGA connection and the xbox would act like it was there, but no picture would show. Moved to a smaller TV with component cables and it worked fine, but screen size was too small. Have now purchased a Lynx Innovation FM-LCD19 Monitor with HDMI port, and, again, the xbox says it's there but no pic. Can connect with component cables but very poor pic quality. Any ideas on how to get the HDMI connection to work?
