Default Re: Denon 3808 video probs???

It is unlikely, some cable boxes and/or companies do not activate the HDMI or DVI-D ports on their units. I had one like this and could get it to work for often months at a time by unplugging the cable box and letting it reboot itself.

Another option is to do a google search for the model # of the cable box and see it you can find the service menus to activate the DVI port (some have it, many are controlled via the RG6 from the cable company.
