citikid Posted March 17, 2012 Share Posted March 17, 2012 Greetings,Can anyone give some advice on the best way to send a relatively long (20-30 meters) HD video signal to a projector?I'd like to keep it DVI directly from a Mac. The projector is sort of old, about 6 years. But it does have DVI input.We've been using s-video from the booth up until now but I need too start sending 720p from the computer. Thanks!

david.elsbury Posted March 17, 2012 Share Posted March 17, 2012 Permanent install or temporary? If permanent, convert to fibre and back again. Temporary, ethernet CAT5 or CAT6 conversion might be the way to go. What sort of budget are you allowing for this? Link to comment Share on other sites More sharing options...
citikid Posted March 17, 2012 Author Share Posted March 17, 2012 Thanks for the quick reply! It's going to be permanent.with my very limited cursory research it looks like fibre is like 10x the price of everything else, is that right?I'd like to keep it under 1k price wise. I guess I'm trying to learn about the different flavors of ethernet vs a DVI "repeater" vs analog conversion. appreciate the input. Link to comment Share on other sites More sharing options...
techywhizz Posted March 17, 2012 Share Posted March 17, 2012 Look into some of the Kramer options.. You can get something like the pt-571hdcp .. This list at around 350 per end + vat, then you can then get some good quality stp cat6.. Less than £1k Link to comment Share on other sites More sharing options...
david.elsbury Posted March 17, 2012 Share Posted March 17, 2012 OP is in New York, by the looks... ;) Edit: Sorry. In my post above I didn't mean "ethernet" conversion. I meant CAT5 or CAT6 cable. I of all people should know there's a difference... :) Link to comment Share on other sites More sharing options...
Olie Posted March 21, 2012 Share Posted March 21, 2012 Another option is blackmagic DVI extended which uses bnc cable. You may get away with using the cable you already have. Link to comment Share on other sites More sharing options...
sleepytom Posted March 24, 2012 Share Posted March 24, 2012 Fibre certainly isn't 10x the cost of other solutions. Decent Cat6/7 cable is quite pricey where as fibre patch cables are quite cheap (around $1/meter) - the conversion boxes are around the same cost. Fibre is better quality, avoids any possibility of ground loops and can cope with whatever format of signal you want to upgrade to in the future (4k? no problem!) Oh and fibre can run for kilometers where as cat6/7 is seriously limited in length. Kramer, Extron, Gefen and Blackmagic all offer affordable fibre options.

addoaddo Posted April 2, 2012 Share Posted April 2, 2012 Get a cheap converter to HDMI which is only a physical converter and use an HDMI amplifier which are also relatively cheap. Whole lot should cost less than £50 Link to comment Share on other sites More sharing options...
AHYoung Posted April 2, 2012 Share Posted April 2, 2012 Get a cheap converter to HDMI which is only a physical converter and use an HDMI amplifier which are also relatively cheap. Whole lot should cost less than £50 And it will be as unreliable and troublesome as youd expect from a solution that adds a whole load of new lo budget points of failure... 720p isnt actualy that high a resolution , have you considered using a simple copper dvi cable? If you buy the right cable, you should be fine. We regularly send 1080p over Kramer 65' dual link Dvi cables without issue, im sure you could get away with longer at 720p, but you can reclock the signal half way up with one of these http://www.kramerelectronics.com/products/model.asp?pid=1480 or similar. High resolution video really exposes the flaws in the cheapo cables, and it pays to spend a bit more if you want a solid solution. If you want transparent plug and play at 1080p, id go for the Kramer fibre products as other than running them the right way round, you wouldnt know it wasnt a copper cable.

J Pearce Posted April 3, 2012 Share Posted April 3, 2012 I had a nice DVI cable as part of a package from XL Video that was apparently fibre for the cable run with the converters built into the DVI connectors. Very smart and very easy to use. Link to comment Share on other sites More sharing options...
brainwave-generator Posted April 3, 2012 Share Posted April 3, 2012 And it will be as unreliable and troublesome as youd expect from a solution that adds a whole load of new lo budget points of failure... +1. I used to work in a place which was big budget, had a lot of TV screens, projectors etc all over the club.. but the whole lot was linked up by composite cable and cheap & nasty £5 converters from Maplin or similar. Yes the signal got from the distribution box to all the TVs, but it never looked very nice, and we spent more time digging up every connection in the building than we did using it. If you're going to install something, install it properly! Link to comment Share on other sites More sharing options...
citikid Posted April 13, 2012 Author Share Posted April 13, 2012 Fibre certainly isn't 10x the cost of other solutions...Thanks to everyone for the advice, especially Sleepytom for pointing out that optic might not be expensive as I had originally thought. I'll probably get one of these options:$495 UShttp://www.bhphotovi...iber_Optic.html or this$630 UShttp://www.bhphotovi...ptic_Cable.html I'm still trying to figure out why the second one is $130 more when they appear to be the same thing. The first is called HDTV - DVI, But the descriptions seem to be the same. Thanks again to everyoneck Link to comment Share on other sites More sharing options...
