I need to run a DVI D dual link connection between my HTPC to my projector which are 30 feet apart and there is a 2" pipe to run wire. I won't be able to insert a DVI cable. Will running a HDMI v1.4 cable and using two HDMI female to DVI male connectors at the end work? Will there be any missing link due to convertions? I was planning to avoid running CL2 D cable with wall plates for DVI and spend over $200 for this one. I would really appreciate your reply.

As long as the signal isn't analog you are sending. HDMI only supports 1080P, not "wheatever the two analog dual-link support".

As long as your projector supports it, fine.  In most cases, you will need a fully compliant HDMI Splitter - this can easily be done with many receivers (PC to Reciever, Receiver Output to projector and to other display).

I say this because unless you are going straight from PC to receiver or other sound source via TOSLINK or analog, you may lose audio output without a split ;)

I'm running the DVI from my HTPC with no Audio to the projector - the Audio is connected through SPDIF optical cable to a receiver. Converting DVI to HDMI and then feeding to HDMI on Projector has quality issues - the screen is not as crisp as direct DVI connection for some reason. Thats why I wanted to retain the DVI input to the projector - but I have a concern that I'm converting to HDMI and then again from HDMI to DVI - and didn't want to lose the quality once again. Thanks.

Again, it all comes down to the resolution you are sending. If 1080P, great. But I have no idea why DVI over to HDMI into the projector looks any different than DVI-DVI...unless the projector somehow is "set up better" for DVI. What projector is this?

I believe that the latest version of HDMI supports 30-inch, 2560 x 1600 pixel monitors (and beyond). The issue is that a lot of HDMI implementations don't. They only go to 1920x1200 (computer monitors) or 1080p (HDTVs). Introducing HDMI Specification Version 1.4a
