We have a LG DT-62SZ71DB (62" DLP Rear-Pro) and we've recently added a HTPC to our setup. I have set up the PC through the DVI connector, using the HDTV setup in the video card. I want to set up a button on our MX-3000 to switch to the PC and assert 16:9 mode. Problem is I cannot seem to get a discrete code for DVI-DTV mode for the tele. The discrete codes available for DVI sets it to the other option: DVI-PC (doesn't work). Anyone with the discrete code I need? Any pointers as to where I could find it? Any help is much appreciated!
