I'm trying to get a new LG 47LD630 tv set up to my HTPC. Previously I had an old toshiba 32". The Toshiba worked fine with hdmi-hdmi after upgrading from a dvi-hdmi, however I can't get the LG to work.
I can dual run monitors with the hdmi-hdmi in the tosh, and dvi-hdmi in the LG but not vice versa.
I think this may be a resolution problem, but not quite sure. The LG will pick up the hdmi-hdmi in the bios, but when it boots into windows losses (presumable graphics drivers).
I have an ATI 5670 card in the HTPC for refernce, with the 11.2 drivers. I've tried both manual and auto detect of displays. The HDMI cable is version 1.3.
Suggestions what to try next? I thought about uninstalling drivers.
