Im running version 2.0.5 on my work desktop (windows 7), My personal laptop (Windows 7) and my work Tablet (Windows 8) and they all seem to be working fine.
Stage Electrics are very good at this type of stuff. If you ask them to come for a meeting with you they will then discuss what sort of things would be good for you and also give you a couple of different quotes for different type of equipment. I use them a lot for hire and sales.
I agree Stage Electrics are the people to contact. I would contact the head office in Bristol and say to them what you want to do. Then they will probable send someone down to your school to talk to you and find out your full requirements. The after service is brilliant.
This sounds like a lamp issue. Does it shoe the blue line and yellowish colour when there is nothing else connected to the projector and you have the big warning triangle?
Yeah i would class this as Dead on Arrival. We had a problem with a couple Hitachi projectors before and the gave us a temporary one whiles ours was being repaired, Very good service.
We have got 2003 around the school and in the IT office we have got 2010. We have had problems with profiles and things if we have staff using 2003 on one computer and 2010 on another. Not sure if other people are getting that problem.
