Picture Quality of DVI cables longer than 10m...

Hi!
I have my HDTV projector connected to my PC over standard Sub-D analog cable, since I heard the image quality of DVI cables longer than 10m literally sucks, next to the fact that they are ridiculously expensive.
I was wondering if anyone has had experiences with these cables at that length, and if there really is a significant difference in picture quality in comparisson to the analog cable...

If you are just speaking of PC, stick with the VGA. VGA cannot convert to DVI though, keep this in mind. We have run into multiple problems with pre-existing projectors run with VGA and using DVI switchers. It's just a mess.

If it is longer than 10m, get a Cat5 combiner and splitter and split your digital out into DVI that way.

Digital is digital, there is no degradation of 0 and 1's. If you want a good price go to www.monoprice.com. That's if you're using the dvi out of your video card to dvi/hdmi on your tv. If you're going vga to vga thats a different story.

My graohics card has two DVI connections, but I have to use adaptors for the normal Sub-D cables, like for my Monitor and the projector.
I've read that the shielding of 10m+ DVI's is too bad, that's why the picture is messed up.
I actually bought myself a 10m DVI cable for 90***8364; the first week I had my Projector. It said it was fully shielded and had gold connectors, but the picture still sucked, so I gave it back the next day and got a normal 10m Sub-D cable, which works perfectly.
It's just that I'm wondering if the picture quality COULD be any better, since my graphics card has two default DVI ports.
I found real high quality DVI cables in the proper length in the net, but I'm not really about to pay 250***8364;+ for a cable, which I wouldn't even be sure of would work 100%.

So would it just be best to stick to the Sub-D, or actually get 2x 5m with a Cat5 Combiner and Splitter?

Havent had any problems with the Cat5 so far. Works purty good.

Hmmm yeah, but would it make an actual difference if I'd change to it?

What's a cat5 combiner? do you have a link?

Its a peice that you plug a cat5 and dvi into and it transfers your digital video down a peice of cat5 to another peice where it converts it back out.

Okay... I guess I'll really stick to D-Sub then, because I'm really not prepared to pay that amount of money for the convenience of higher quality cables, especially due to the fact that the picture might not even be better....
Nevertheless, thanks guys for your help, much appreciated

If I buy one of those in each room, are you saying I could have HD quality broadcasting in each of my rooms? (And yes, I already have CAT6 running throughout my entire house and a central gigabit switch).

If so, hot damn, I would love that. I am assuming I could even use a PC or a router to direct the traffic and control what data goes to what room.

No. Needs to be direct. It's not a network device. It just uses CatV wire for the transfer.
