I don't have $ right now to build a dedicated HTPC, but would like to still reap the benefits by using my current PC. I would need about 50-75ft. Is this possible? I figure that if it would be, it might be so expensive as to just about cover the cost of an entry level HTPC.
To prevent ghosting, you need cable with a 75 Ohm impedance.
Get yourself a VGA->5 female BNC break-out, and use a set of matching RG-6 cables. Some time in the future, find yourself an interface (like the Extron RGB202) built for driving long cable runs.
Drew is correct for the best possible image use coaxial 75 Ohm cables but if you don't have the available funds for those then CAT 5e does work well [ as many others here on the forum have found ] .

RG-6 is under twenty cents a foot. .20 * 75 * 5 = $75. RG-58 is even less expensive. If your graphics card and projector support sync-on-green (RGsB) you could do it for $45 in cable with RG-6.

While I do agree that true 75 Ohm cable is the way to go , you guys probably are not aware that the 103XQ sony's do not use RGBHV BNC connections so using Rg-6 is not an option here unless you get the actual breakout box from Sony direct [ and it is spendy ] .

-- Wow , $24.00 for a 50' VGA - that is cheap and the cable sounds good too .
hi, i can attest to the products that rogersystems sell as well.they are very nice for the price point.i use there vga to bnc cable now($8) with great success...
long runs of vga high bandwidt ask for topquality cables . They don't come cheap. There are two alternative solutions. Use a set of vga baluns which allows you to go as far as 350 feet with cat5 cable. Another solution is to use a line driver. Anyhow, using topnotch cable is the only way if you are talking about moderate lenghts. Look at the specs. You should at least use cable with att of at the most 5dB/100ft at 100MHz. eg Altinex or extron
If your supplier can't give you the specs, don't be tempted to buy it, even at a low price.
Thanks a lot for the info. I'm still on the fence. I figure that it won't cost a lot to try the cat5 thing because I have an old 100ft crossover cable that I don't use anymore, so I can rig it up tonight. If things don't work out, I will probably give the Rogers Systems stuff a try.
One more question, is cat5e the regular blue stuff used for networking, or is there cat5 AND cat5e?
I dunno about cat 5...I was just making some cables from my hub to a new machine and it is NOT sheilded. BUT if you get the picture Jason gets from his 1031Q then go ahead and use it! For my line doubler to my 1272Q Sony I use http://www.pccables.com 25ft SVGA extension cable. Has RF barrels at each end and they guarantee no ghosting. I use a HD15 to 5BNC breakout cable at the projector end. Great picture for about 2 years now. For $16 it is a steal! The 75ft is only $43. Not bad.
I'm wondering about soldering a cable myself, using the Supra AV-6 ( http://www.jenving.se/av_digit.htm#av_d_tbl ) and soldering a hd 15 in one end, and 5 bnc's or db9 (BD 801 port 3) in the other.
Does this look like a good cable? I have about a 30' stretch.
Hey Jason. I'm needing to build a longer run from my doubler to the 1031q.
When you build a cable using cat5e shielded, does it matter which pinouts you put through a specific twisted pair? Is there an optimum way to minimize interference?
BTW, thanks again for the pinouts, my first cable works great. It's just too short since I canibalized it off of a dead monitor and added the 25pin.
Okay, here's my test results with regular CAT5. I work for a telco company and was able to pick up a box for free. I ran about 50ft and soldered the HD15 ends on. I'm getting noise. I'm getting a bunch of diagonal short lines all through the picture. You can see everything okay, but it's distracting; kinda like snow, but not so noticeable. Actually, without my glasses, I can barely see it, but once my glasses are on, I can't watch it. What could be the problem? Is it that I'm not using CAT5e? I'm gonna pick some CAT5e and try it again.
I'm pretty comfortable with my soldering skills, but know nothing about cables or anything. There are 4 sets of twisted pairs in the cable. How do I wire these to the SVGA ends?
I'm currently using...
CAT5 ---> PINOUTS ON HD15
orange ---> red
orange stripe ---> red ground
blue ---> blue
blue stripe ---> blue ground
green ---> green
green stripe ---> green ground
brown ---> vertical sync
brown stripe ---> horizontal sync
If I go with the CAT5e, how should this be different? What do I do with the shield? Is each pair shielded? Is there only one shield around the entire cable?
Any help? I'd like to get this thing up and running soon. I've already wired keyboard and mouse ports from my computer to my living room using CAT5, and they are working fine. I'm also gonna take some rg59 home tonight to run my spdif cable.
Thanks for the help.
BTW, I'm excited, this is the longest post I've written, PLUS it's the one with the most responses. (giggling like a school girl )

You're right, but... take a look
(i'm sorry for the low quality)
