mac pro and viewsonic vp930b lcd display

i have two monitors set up, a viewsonic vp191b and a vp930b lcd, connected via both dvi ports on the mac pro. the vp930b when the computer goes to sleep cycles on and off with the input message. if i put the mac pro to sleep via the menu sleep command, the last graphic/image on that monitor flashes on and off until i power the unit off, then it cycles on and off with the input message.
the problem is, the mac pro is not letting the display enter full low power mode and is sending some kind of signal still causing a cycle. the monitor works fine on other computers, the G5 i had pervious, and others i test. i tried switching ports and re-routing the cables, same result, the vp930b is still not allowed to enter full low power mode and starts an endless cycle of the monitor going from low power mode back the input mode.

i tried that. it is only the one display, if i switch ports on the card, it still only does it to the same monitor. since it does not do it when the computer is off or starting up, the second monitor 2 port does not come on until the the login screen is near, and flashes an image on the screen, i know it is somewhere in the hardware or software. the mac pro is sending some signal to the vp930b still when it should not be. i know the displays and mac pro communicate with each other via the dvi link, so it is unique to this display.
