SVGA Cable - can I cut and extend it?
Hi Group.
I have an SVGA cable (15 Pin D) connecting my computer video card to an overhead projector. The cable is too short for comfort. I want to cut it and insert an extra 2 or 3 metres. A new cable is too expensive and the 15 pin plug is too tricky to solder. I have done an exploratory incision in the cable (no cuts yet!!) Under the outside wire and foil screen I find 9 coloured wires and a further (unknown - maybe 6??) number of wires in a secondary aluminium foil screen. Should I stop now and leave well alone? If I proceed and hack into the inner cable and then extend all the leads by 2 metres and try to botch up the screening on the inserted part, will I suffer hopeless loss of signal quality or will it hardly be noticed? Any advice greatly appreciated. Ger P.S. anyone know if ALL the 15 wires are actually used? |

11 of the 15 pins are active. However, 2 meter
cables are available for about $6 in my part of the world. Why take the chance? What happens when this doesn't work correctly? Now you'll have a trashed cable and you'll end up having to buy a new one anyway. "Ger" wrote in message ... Hi Group.

If I proceed and hack into the inner cable and then extend all the leads by 2 metres and try to botch up the screening on the inserted part, will I suffer hopeless loss of signal quality or will it hardly be noticed? Any advice greatly appreciated. I'd suggest and purchasing a KVM extension cable. Don't underestimate the value of cables produced and soldered by either automated means or people who do it for a living. They're not as expensive as the time it's gonna take to do the work to extend what you have, and likely you'll see a rather disappointing drop in quality introduced by the cable work you might do (unless you are extremely careful and skilled, and use high quality cable). Cheapies: $7.16 Tripp Lite GOLD VGA Monitor Extension Cable, HDDB15 M/F, 6' http://www.cdw.com/shop/products/def...spx?EDC=326389 $8.00 Belkin HDDB15M to HDDB15F VGA Monitor Extension 6' cable http://www.cdw.com/shop/products/def...Type=alternate If you're running at high resolution, you'll want a cable with co-axial RGB leads that make a very noticeable difference in video quality at 1024x768 and up (depending on the monitor's sensitivity to inexpensive non-coax cables): $27.14 Belkin HDDB15M to HDDB15F VGA Monitor Extension 6' cable http://www.cdw.com/shop/products/def...Type=alternate Best REgards, -- Todd H. http://www.toddh.net/ |

Ger P.S. anyone know if ALL the 15 wires are actually used? the cables are shielded...so if you try to splice it you will get a "ghosted" image you need to by a *high quality* extension cable if you use a "cheapie" you will also get a "ghosted" image |

If you cut into it and add a section, you'll undoubtedly end up with signal
interference. -- DaveW "Ger" wrote in message ... Hi Group. I have an SVGA cable (15 Pin D) connecting my computer video card to an overhead projector. The cable is too short for comfort.

Thanks Pen.
FYI, cost of 2 metre extension SVGA cable in UK is $26 :-( Ger "Pen" wrote in message et... 11 of the 15 pins are active. However, 2 meter cables are available for about $6 in my part of the world.

The longer you make the cable, the more it gets attenuated and the more likely RF and EMI interference will cause problems. Many KVM users have found they need to use high-quality, low-impedance cables because they are lengthening the overal cable length. Cheapie extender cables will cause ghosts, noise, reduced brightness, and other defects. If the cable disconnects from the monitor (i.e., you have connectors on both ends) then get one longer cable instead of tacking on a extender. -- __________________________________________________ __________ *** Post replies to newsgroup.
