I use VGA splitters staff computers at school to clone image to overhead. I have one computer right now that monitor loses connection as soon as the overhead is turned off. How can I keep connection? Now we have to disconnect overhead and monitor comes back. Plug and play monitor, HP tower with DVI and VGA outputs. Monitor VGA only. LCD VGA only. Am at my wits end.

Is the system's video card by chance dual monitor capable? If so, an option would be to use a DVI to VGA adapter. That way, you could connect the primary monitor to it leaving the VGA connection open for the overhead projector.

In Display Properties under Settings, you would just need to un-check 'Extend my Windows desktop onto this monitor' for the projector connection which would be set as monitor 2.
If that will work, here's one place that carries the adapter: http://tinyurl.com/5ondqd
Note: this is not an endorsement of this supplier, it is meant to be an example.

Thanks. Great thought, but not dual monitor capable. (dang!)
I am just about to give up and tell teacher she needs to plug connection into wall or computer whenever she wants to show something on overhead projector

Every now and then you'll find one that doesn't meet standards.
Try swapping it out with a known good one.
