Ditto! Same issue here. Newly installed, updated and "upgraded" Ubuntu 14.04 LTS. Monitor ASUS 27" through HDMI. After the established timeout, screen does blank out, and monitor detects the "poweroff" and starts powering off. But then the lock screen comes up with request to log in password, and monitor comes back up again and stays on infinitely.
I'd say this definitely looks like a bug, because the monitor does detect the shutdown sequence. It looks like a bug (or missing monitor shutdown sequence) on the lock/login screen. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

I can wait as long as 10 minutes after activating the lock screen and the monitor still doesn't trun off. Then when I unlock the screen and don't use mouse or keyboard monitor will turn off (it's about 5 seconds after unlocking).
