So i have a new setup in my house with all of the following devices. Denon 1912, redmere 50 ft hdmi cable, and a HTPC with an ATI 6670. I have the denon displaying onto a JVC rs45 mounted on my ceiling. Today I just got the setup completed. I have been previously using the HTPC, denon, and a Samsung tv with no issues. I just got the setup installed today and there is no video from the HTPC.I can get cable just find from my cable box -> denon -> projector, but somethings going wrong with the new setup. Does anyone have any ideas where to go from here?
