Most DPMS blankers include this warning in their manual. If your monitor doesn't support power management this software may damage it.
I'm running a double monitor setup: One monitor is a RGB Philips CM8833-II, which i use exclusively for retro gaming and it doesn't support power management of course and the other is a SVGA one which i use for everything else and i have connected it to my gfx card. This one supports DPMS alright.
If that matters, the blanker i'm using always brings the WB screen (C-GFX mode) up front, before it activates the power management signal. The SVGA turns off succesfully. I hesitate to do it while the RGB monitor is ON. I will wait for some input.
Thanks.

I once fried a Commodore 1084S when I went for a shower and forgot that the blanker was active.

It can destroy some monitors which don't support DPMS and aren't protected against such conditions. DPMS used the sync signals to tell the monitor to turn off by setting them to low (or high?). A monitor which doesn't expect this signal will drive the deflections coils to the extent of their range and keep them there. This can damage the coils and their driving circuits quite quickly if, like I said, there's no protection for such conditions.
