- Update your screen resolution (720/1080); it can be then be swapped back afterwards.
- Update your aspect ratio to standard definition; it can then be swapped back afterwards.
- Check and/or reseat your HDMI cables to test.
- Try a different port on the TV itself (if available).
- Try rebooting your box while your TV is on.
- Try turning on the HDMI CEC setting (Settings --> General --> HDMI CEC settings --> Enable). Save and reboot.
- Try a sequential reboot of your STB/PVR (unplug power cord from your modem/router, then unplug power cord from your TV equipment, wait 15 seconds, and then reverse the order by plugging the TV equipment power cords back in, and then finally the modem/router).
- Try a new HDMI cable if you have one, or try an optic cable (some Denon receivers need an optic cable to work).
