I have a 65" Mitsubishi Diamond Vision (ws65713) set that was released before HDMI was available. The set functions beautifully but now with so many HDMI devices I need to employ a HDMI switch. I have tried a Monoprice HDX-401TA AND IT IS HIT OR MISS MOSTLY MISS. I have an Oppo Blu-ray and Toshiba HDDVD Player and an XBOX One I would like to add as well. The Oppo and Toshiba work fine connected directly to the dvi port so I know the problem is the switch. Most of the time I'll see the Oppo title screen but that is all. On the other hand I'll get a movie to play but the very next day the exact same hook up fails. I have tried two of these devices and they both work perfectly on my Panasonic Plasma which is native hdmi. Any recomendations for my setup?
