Problem with hookk up of desk top computer monitor with Infocus projector

At work I have a desktop computer hooked up to the network.  I also have an infocus projector that I would like to use. The problem is that if I hook it up correctly it works fine and I can use the desk top monitor as well. But when I turn off the projector ( when not in use)  it also disconnects the monitor.  It seems that the  projector plug in that allows the monitor to be used disconnects when the power is off and this is not what I need.

I connected an averkey and it does the job, but the picture quality of the projected image is terrible and this isn't going to work out.   Is there something else out there that I can use. Some where I read about a vga distribution amplifier, but what it looks like is the averkey and I have been down that route.

Do I want to buy a KVM and use that or do I  buy one of those rotary switches and select the ports to use or do I plug and unplug cables as I go?

You could do any of several things:

(1)  Replace the video card with a dual-display capable card and just attach the projector to the 2nd display output.

(2)  Split the VGA signal with a distribution amp (this SHOULD work fine ... your experience with averkey notwithstanding)

(3)  Use a simple VGA switch (http://www.shentech.com/ds152.html)

I would NOT "... plug and unplug cables as I go ..." => hot plugging is not a good idea;  the switch (#3) effectively does that, but in a "safe" manner.

I did some research and on the distribution amp and I see that Infocus has one available and "The Nerds"  has  a good price.   I'll explore that.  

Ideally, the unit at school has a dedicated laptop that attaches, but I don't want to deal with the headache of storing it off the cart part of the day .   I'll expore the vga switch as well.

I appreciate the assistance .    I am just coming to grips on the cost of  a replacement lamp ... sheesh..

Yes, the lamps aren't cheap :-)    [I wonder how many folks who have purchased DLP or LCD rear-projection televisions in the past couple of years realize that they have a $200 - $400 light bulb they'll have to replace in a couple of years !!]  (and in some cases they're not easily user-replaceable; so they'll get to pay someone $100 to replace a bulb !!)

I am assuming that one day the price will drop or.. newer technology will come in to play that will be less costly.

Anyway.. appreciate the assistance.

ok.. rindi.. took the hint.  SOme of us actually do leave the coffee shop..

Purchased from The Nerds, a vga distribution amplifier and although pricey, works very well.

The reason I haven't been updating this gem.. very sick.. but am able to sit in chair.    Let's for the good of the party, consider this closed.

Sheesh ,
