Windows 7 - Relisys TL795-RU

I am setting up a new Windows 7 system for my wife and decided to use my spare Relisys monitor. However when I connect it up I get nothing but a black screen. I am presuming it is the drivers as it was working fine under XP. I cannot find a disc anywhere and in any case I imagine I would need Windows 7 version anyway. I cannot find the drivers anywhere. Has anyone out there got these that I can use or could I be directed somewhere so I can download them.
Any help would be much appreciated

Are you using the same computer and just installed Windows 7 on it and now the monitor will not work or is this a complete new build from ground up?

Have you tried a different monitor onto the computer to rule out the monitor as the problem?
Have you tried the problem monitor on a different pc to see if it actually works?

The Relisys was originally on the system I am typing from now but I did a clean install of Windows 7 on this one and attached a new monitor (the Relisys now no longer displays on this system). I also tried my new monitor on the Compaq system I want to now attach the Relisys to and my new monitor works on that. The Relisys works on neither. The power up button comes on and all I get on both are black screens.

Check the VGA cable end to see if there are any bent pins inside the connector, if not then I would say the monitor is bad.
