I installed 810 and using my VGA output I see the AV menu and the NIC card is recognized. However, I want to connect the computer to an HDMI out. How do I set up the PC directly connected via HDMI if I cannot see the A/V menu? Shortcuts associated with 710 (1,2,3,4,5,...) do not seem to work. Is there a way to connect "blindly"?
