Any Disadvantage Using DVI-HDMI Adapters?

I don't think so - quality is not compromised - after all it is all digital. Provided the source is outputting data that the TV can decode. I use DVI-D (digital) to HDMI from my Mac to my HD TV - this way I can select tracks to play from the listening position by using a wireless keyboard. Note that when (if) they start protecting video against piracy then some devices will not accept digital HD signals except through HDMI...

( I had to hack the Mac standard operating system by programming the Video card to output 720p, as this was not a native resolution on Mac OS but it all works seamlessly now)

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.

I changed projectors and went to an Oppo 970HD dvd upscaling player. I found that my previously installed DVD cable neeeded an adapter to HDMI. I also obtained it from Monoprice.com and have been thrilled with reslult! Absolutely no issues.

What kind of DVI does you rprojector support????

There are TWO kinds.....analog and digital!!!

Some devices accept both and will default to digital if it detects the signal.

If you have an analog DVI only then it is probably not much different than component - although component cables may have better shielding...

Shadorne, I changed projector to one using HDMI; I had an installed DVI-D cable in the wall/ceiling, so I used a couple DVI-D to HDMI adapters to connect the projector and Oppo. Works perfectly.

UncleJeff,

I agree with you, I destroyed the HDMi output of a switcher for just such a reason. The added weight of the adaptor is large, and the leverage it affords the connector (read..YOU!) is also way more than these connectors were designed to do.

I for one would have liked to have stayed with a connector closer to DVI-D as it is more stable than HDMI, but that is my oppinion and worth as much!

Kennyt, No doubt; the HDMI connection certainly is not the most secure I've seen, and those miniscule conductors are accidents waiting to happen. I can certainly understand situations where the stress on a connector can potentially harm a piece of equipment. I have many times worked with power cables which are extremely heavy and stiff. They will literally pull halfway out of the outlet when moved. In such cases I use twist ties or other means of securing them to the rack so that they cannot move. With that in mind when I installed the DVI-D to HDMI adapters I was sure to reduce any stress the cable and adapter had on the DVD player. It certainly would not be good for a heavy cable to dangle from the HDMI port. I recall that I noticed the downward pull of the cable and moved the player forward on the shelf so that the weight of the cable was held up by the back edge of the shelf it rested upon. That way no weight was born by the HDMI socket. Possibly something similar could be rigged so that the adapter will not turn or be a burden on the connection point. If the cable is long enough, possibly loop it once to secure it to a post on the rack before insertion into DVD player. Or maybe weight the loop down with a heavy object hidden discreetly behind the component...

Yeah, I had mine all supported. Then, one evening I reached back to secure another cable and...no more HDMI. The cable fell from the prop and the weight of the DVI plus adaptor did the rest.
