dual monitor standby problem

[dkreifus]

I have a dual monitor system setup.

Video card: RADEON VE 7000.

Monitor 1: BenQ FP731 Flat panel

Monitor 2: Dell P780

When the screen saver comes up, both monitors work fine, but when it comes to standby more, the Monitor 1 goes to standby, and Monitor 2 goes to normal mode.

How can I make both go to standby?

(No, I'm not running hydrovision or catalist, just the standard drivers)
