Monitor help Windows 7 blanking out

Windows 7 x64
5 23" monitors
1 32" TV
1 55" TV

The 55 doesn't show until it's powered on, but in doing so it blanks out the others and brings them back. While doing this is moves my windows, task bar and gadgets around. How do I keep it from doing this?

I've tried EDID, power options on USB, etc... nothing fixes it.


Thanks in advance

Ron

Is it because you are dealing with different aspects, resolutions and refresh rates?

When you turn them all on they may be taking some time to agree on settings for those variables.

I never have more than 2 monitors at once but you could try something like DMT from sourceforge.
http://dualmonitortool.sourceforge.net/index.html. Then again with your rig there may be something that works better.
