I've been using the component input on my AVR2310CI from my PC for a while and that was working fine. I've maxed out my component inputs, however, and decided to switch to using a DVI to HDMI converter and input to the Denon using HDMI (and EXT IN for audio) from the PC. It doesn't seem to be working, however, and I was wondering if anyone had any suggestions. It is a long hdmi cable (~25'), but I ran it directly to the TV and there were no problems and the picture looked great.
Another issue that may be related... when I have the source selected for the PC, the audio comes through but emits a high pitched whine. If I select another source for video, but keep the audio from EXT IN, the whine goes away and the sound comes through clear.
Any suggestions? Thanks in advance for the help.
