I have purchased one LCD TV & no wire is visible near this TV as one electric wire going from this point & I have placed all the wire inside this & it is working properly. Now I want to insert one VGA cable but it can not go through this pipe as this pipe is only 1". So I will have to cut a 5 meter VGA cable & will have to insert into this pipe. The end which will come out of the wall will have to be soldered again. My question is that if I solder these 15 wires, Is there some problem with the picture quality. Is this possible to solder all these 15 wires without any problem? Kindly advise so that I purchase this 5meter VGA cable & proceed accordingly.

Close proximity to electrical wires can be a major problem ...

by OldER Mycroft In reply to VGA CABLE JOINING

I would not advise forcing a VGA cable to co-exist within this 'pipe' alongside live electrical wiring. You can experience bleed-over from the electrical current causing fluctuations and distortion to the video carrier signal.

Could it not be possible to arrange for a 2nd 'pipe' to cater for the video cabling?

Any decent quality VGA cable will not be made up of 15 individual wires.

There will be 3 to 5 coaxial cables for the video signals and possibly a shield foil or braid over the entire cable bundle.

Any kind of coax or shield braid is difficult to splice.

I have used coaxial splices. But, they are expensive and require special equipment for installation.

Do you truly need to use a VGA cable?

Have you considered a video card for the computer that has a S-video port?

If I had no option but to use a VGA cable, I would cut off 1 end and then install a crimp style 15 pin miniature "D" connector on the end of the cable. Not an IDC style like a CAT 5 cable, but a connector with individual crimp on contacts for each wire. With the correct tooling, you can remove the pins from the connector if you ever need to remove and reuse the cable.

I would use a metal fully shielded strain relief on the connector to maintain shield integrity.

You can buy this cable already made. TrippLite Easy Pull VGA cable

by robo_dev In reply to Coax

Somebody makes such a cable

Tripp Lite's 100 ft. SVGA/VGA easy Pull Monitor Cable with Connectors makes running long length video cables a snap. The pull-apart design allows the cable to be run through conduit or other tight areas that a HD15 connector wouldn't fit through. Diameter of the circular DIN end is only 7/8". Circular easy Pull connector is threaded to ensure maximum security once the cable is reattached. The mini-coax (RGB) and paired video wire construction delivers superior signal quality. Double shielding (foil and braid) provides maximum EMI/RFI protection. Both high density DB15 males are molded and have integral strain relief to ensure they last a long time. Tripp Lite warrants this product to be free from defects in materials and workmanship for life.
