“Two HDTV setup. How can I make it work OK? Hi, I too have a problem with two HDTV setup. Samsung identical 42 inch LCDs. 12 feet cables out and 6 feet In from Cogeco HD decoder. What can I do to have both TVs display together. One at a time, it works OK. If both are powered ON, no signal from source on both TVs. Maybe a picture flash sometimes... Is there a possible parameters setup in TVs some user found somewhere? I tried 1080i and 720P from the decoder. Same result. Help please...”
