There are a lot of powered and passive CAT5E-to-VGA converters out there. I am going to try to get the electricians to give me a 1-1/4" flex so I can run a VGA cable (with the ends on it) from under the table to the projector mounted in the ceiling. In lieu of doing that, anyone have success using converters? I crimped a male DB15 VGA end once and it was a pain with all the jumpers. Also, they noe have these component-to-CAT5 converters (passive) and they also have audio. Anyone use them before?

Of course I don't remember the name of the product, but we've used some cables that had a small metal connector on the end that screw together with the DB15 ends. The inline connectors are small enough to get through 3/4 conduit. I think Graybar carries it. The manufacturer is somewhere in Iowa.
Ditto on the crimping connectors. We did one project with almost 30 ends.

These ones work. There are different models depending on the resolution you require. The price goes up with the resolution. https://www.muxlab.com/products/products.html

Have you considered using an S-Video cable? Most laptops and many PC's now have an S-Video output. Much smaller cable.

I wouldn't provide S-Video as the only input to a conference room projector. While some newer laptops have it, many do not, nor do most desktop units. I would certainly provide S-Video as well as Composite video as additional inputs. I've never actually used the cat-5 vga extenders, but the folks I've talked to who have used them have been happy.. Actual results may vary depending on distance, resolution, and actual equipment used. Of course I don't remember the name of the product, but we've used some cables that had a small metal connector on the end that screw together with the DB15 ends. The inline connectors are small enough to get through 3/4 conduit. I think Graybar carries it. The manufacturer is somewhere in Iowa. Would that the the EZLINX stuff from Liberty? https://secure.libertycable.com/pro...utions%20brochure%20-%20CS%20version.pdf There also exist VGA connectors with terminal block terminations. Markertek carries them. I would still fight for the 1.25" conduit.. you never know what the next technology advance will be. You never know when they might decide that they need DVI cabling to the newest projector.

Gentlemen, thank you for the links and consultation. I have used MuxLabs for years (twinax baluns) but haven't tried their VGA ones yet. Thanks twistedpair. I checked out Liberty Cable's web site, tantivy. They send me catalogs all the time. EZLINK is a trip. Change the ends and you change the interface - very cool.

twisted pair:
you can buy the Apple brand DVI/VGA converters for around 5 bucks. They are really cheap. Eventhough made for MacBooks, works on all PC's too.

bfdatacom,
If you have not purchased your overhead projector, try finding one with integrated wireless.
We installed one for a company which had a feature: the software allowed for the PC's desktop to be wirelessly carried to the projector which then projected the image on the screen. Not sure of the make, they just hired us as grunts for the grid ceiling installation.
