I bought a new fully loaded rMBP last week and thus far it's a great machine.

I also bought a Belkin Thunderbolt Express dock with the computer and am pushing two Samsung S23C570 external displays in clamshell mode via MiniDisplay --> HDMI. One screen is connected directly to a Thunderbolt port on the Mac, the other is connected through the dock.

My problem is that whichever monitor is connected through the dock won't go to sleep. It keeps blinking a black screen as if it's looking for a signal, which tells me that the dock is still powering that port and keeping the display awake.

Anybody else experiencing this? I can't find anything on the Belkin support site but I'm wondering if it's fixable at all.

(And yeah, I know I could just plug one display directly into the HDMI port on the Mac, but that port is on the opposite side of the computer and is a bit inconvenient with my desk setup, so I'd rather run everything through the dock if I can...)
