This is one thing I always stress to my friends and family when they ask me questions...Google is your friend.
Here is a site that has the manual for the Optoma...http://www.manualowl.com/p/Optoma/EP732/Manual/116410
I don't know anything about Mimio, but guess what...http://www.mimio.dymo.com/
And the "splitter", they MUST use something like this when sending a video signal to multiple displays...http://shop.texasmediasystems.com/Extron-P2-DA2xi-Two-Output-VGA-Distribution-Amplifier_p_1054.html
There are cheaper units, a lot of them are junk. But anytime you "SPLIT" a video signal, the level available to drive the display is cut dramatically. You may well see the image improve if the splitter were removed and the output went straight to the projector.
Your use(or misuse)of terminology concerns me. You said cables coming out of the hard drive. I hope you meant "computer" or "computer tower" as the hard drive is an INTERNAL component that would not have monitor cables coming from it.
And then there is the comment about "plastic piping" and "panel". I have no idea what you're talking about there. It helps us help you when the descriptions are accurate, because if we have to guess, we could be way off.
By the way, both projectors are at least 6 years old and should be replaced with new projectors when feasible. You do not want to spend a dime on any repairs for those should it come up.

Not sure if I replied to your last response! So stressed out over these projectors not working. I am only seeing the post and all responses when I click reply to topic also. The other lab has the projector Optoma EP 732. (Boy do I need my glasses) Checked the back of the hard drive. Yup. One in two out. Basic Cables. A Sherwood Stereo is back there too which I guess would be good for sound but the plastic piping connecting to the panel is annoying. Can't find its remote either. Thanks for links on the other projector. Haven't been able to do much in either lab with the students. The problem also is this.... I just have to wait until they get back to me about the bulb or decide to come out and check it. At least now I will know what the projectors really need and be able to discuss it when them. Please tell me what you know about the Optoma and there is also Mimio software for the screen and the screen panel but the other teachers didn't use it. I think it makes the screen more interactive I am hoping. Do you know anything about using Mimio with the screen?
