Q: 24" LED Cinema Display does not go to sleep mode since Mavericks

Hello there. Since I updated to Mavericks on my Mac Pro 2009, my Apple 24" LED Cinema Display will not go to sleep anymore. Screensaver starts up at 5min mark, as usual, but display won't go to sleep after 10mins as it should. It is connected using the mini-display port to the ATI Radeon HD 5770 1024 MB that is installed, with USB plugged directly into the Mac Pro. Any ideas?

LED Cinema Display (24-inch), OS X Mavericks (10.9)
