Question

Which cable do I buy?

by PKMasta2 / March 7, 2013 12:48 PM PST

I have one computer in my classroom, an older PC. I have a fairly new projector.
To make the PC project I have to run a 30 foot cable across the room to the projector. This is awkward, but not the problem.
The PC only has one VGA plug and isn't set up for 2 monitors. To use the projector, I lose the monitor. Using the mouse on a projection 30 feet away is problematic.
I have USB ports and a serial port to spare on the computer tower.
I need the least expensive solution. Is there such a thing as a splitter I could attach to the tower? What about VGA to USB cords?
If you can lend some advice, you will have contributed to the education of 100 kids and you'll make one teacher a lot less awkward with basic tech. Thanks in advance!

I would suggest ...

this inexpensive vga video splitter. You run a vga cable from the computer to the box, a second one to the monitor and a third to the projector.

Another simple fix would be an inexpensive second video card or replacement card which could have multiple ports. The type of card would depend on the bus slot you might have available on the older computer.

You didn't provide details of your current PC, etc. yada, yada. So, below is a generic answer...

Replace video card to have dual video ports is the best solution. -OR- if you get an adapter that it supports what you want to do. The issue with the adapter; you have an old PC and probably XP, will the adapter accept XP OS and be capable. As for the 30ft. cable, unless it came with the projector, anything over 15ft. tends to fail or be "iffy". Since you use VGA video, the adapter may seem the best way to go since it provide dual VGA ports. Finding a dual VGA video card is dated and/or dual anything wouldn't normally be VGA, VGA and DVI or HDMI. A simple card like a ATI 5450 is cheap and provides all video type, but you'll still need some adapter but the video card would generally more openly be supported.

adapter = look for some splitter for multiple video outlets, 1 in -> 2 out

Now google away and take my advise don't settle for the cheapest, you have a complex problem, quality does matter.

If your video is AGP based, try as best you can to get a PC that has PCIe-16x. That way you support better video options -OR- provide a better platform to make things work. If its too old, you'll probably have to toss your fixes out when you do get a newer PC(very probable).

Maybe the school has one you can use when needed?
