Default DPMS over DP->DVI adapter not working

I have two Dell P2411H monitors connected to a Quadro FX 580 (with one DVI port and two DP ports). One of the monitors is using the DVI port, and the other one is connected to one of the DP ports using a (passive, I think) DP->DVI adapter.

Whenever DPMS standby/suspend/off is activated (for example, by running xset dpms standby/suspend/off), the monitor connected to the DP port starts cycling between on and off. I.e. it doesn't stay off. The monitor connected to the DVI port stays off, like it should.

Exiting DPMS works correctly though, both monitors come back up (and stay up).

Is this a known issue? Or is my DP->DVI adapter broken?
