Any Disadvantage Using DVI-HDMI Adapters?

As I don't know your setup I can only relate my experience with adaptors and such. In my case dvi and component are the same. Mt tv,a 3year old Mits /without hdmi--but has dvi. ----I would guess because my tv is only 1080i is the reason. (?) Just to complicate things I guess it might also be the quality of the component cables I use. For a 1080p set I would say hdmi should be the way to go.

Thanks for all responses. My 720p projector only has DVI, no HDMI. Guess I just have to try out and see if DVI-HDMI would yield better picture quality compared to the component cables that I'm currently using.

On another note, is there a difference between a cheap HDMI/DVI cable(probably <$10) and a branded cable like the Verastarr costing more than $200?

I use monosource.com for my cables, they are priced well and they have hdmi switchboxes, dvi-hdmi cables, etc. You may want to confirm that your dvi port is hdcp compliant (can you connect a cable box to it?) to receive hd content on it.

Ryder,
Non whatsoever, assuming the quality of the wire is the same.

HDMI carries audio and video
DVI carries video only. It has been the pro standard until HDMI came along.

As a matter of fact there is a problem. The DVI head, plus adaptor is too heavy for the HDMI female to support.

Over at AVSFORUM there are lots of us who have regretted doing doing what you propose.

My HDMI from my Dish satellite box is now useless. Get yourself a cable with DVI at one end and HDMI at the other.

Otherwise, to answer your question there is no signal loss.
