Same problem here. I have connected the HDMI output of my ASUS UL80VT laptop to my television's HDMI 1 input and configured the TV to use HDMI 1. The TV indicates there is no video signal, and it seems like Windows 7 64 Ultimate does not "see" my HDMI output when I connect to the TV. I have clicked the "Detect" button from the settings screen, but all to no avail. Note that under Display Adapters in the device manager that there is a device named "Unknown Device", but I suspect that may be the unused VGA output, which incidentally does work fine when I connect it to something. I have sent a request to ASUS support, but I believe this is actually a Windows 7 64 issue. System information:
