    Well, after much deliberation I decided to go ahead and get a Benq 5120 shooting a 92" screen.

    To get the best picture quality I want to connect it to my HTPC(ATI9600XT) via a long... DVI cable. 15m are needed due to the room topology and to avoid low WAF.

    I am worried that, although the Radeon 9600XT is pretty good at sending DVI signals over long distances, there may be problems with the 5120 locking with the signal.

    Have any of you 5120 owners come up to any problems with such long DVI cables.

    Before I go on and order the DVI cable I would like to know if it is a no-no and opt for component or VGA instead.

    Any comments will be much appreciated.

    Hi Lucas,

    I think I read somewhere that its not recommended for a DVI cable to go over 7.5 Metres. Although I think you can buy special cables which go over that. Check Out Lindy.com, they sell lots of cables.

    good luck!

    You really need to try out any cable your contemplating before you insert it in your ceiling.

    BetterCables have 15m DVI cables that will handle 1080P with ease - though your reliant on your source and display to ensure there's enough current to get the signals along the cable.

    See http://www.bettercables.com/15me4febecad.html

    If you find you have a problem with a cable you can either try a different brand of cable or when all else fails add a DVI signal amp to your set up - the Gefen EXT-DVI-141HD DVI Extender works well and doesn't introduce any visible artefacts.

    See http://www.gefen.com/kvm/product.jsp?prod_id=2195

    Both products are HDCP complaint.

    Best regards

    Joe

    Lindy do cheap half decent DVI leads that can run some distance. But 15m is stretching it and Lindy leads aren't *that* good. Bettercables is the best option (hell they can do 31m now!), I get on better with these than other brands we've tried (Wireworld, QED, Chord, Kimber)

    Thanks guys. That's what I suspected.

    I will try DVI to see if it works but I am not prepared to go those heigts (price wise) given that the projector only costs $1000.

    It seems that a good compromise would be either component or vga.

    Has anyone tried these connections on the Benq 5120?

    I tried DVI at 10 metres with a cheapish cable and was getting blue banding/sparklies. It wouldnt lock the 5120 at any decent (highish) res either. I switched to a 7.5 metre Lindy one and all was fine.

    Can you get a high quality demo/loan cable to test with ?
