I have just purchased a Dell P2411H monitor for use with my 13 inch MacBook Pro. The display has generally worked well so far. However, there is one problem. The monitor is unable to enter "Power Save Mode" unless the computer is manually put to sleep. My display is currently set to sleep automatically after 15 minutes but once this happens, the monitor indicates that it is "Entering Power Save Mode" then turns back on, then says it is "Entering Power Save Mode" before turning back on again. This cycle continues repeatedly until I interrupt it. I am not sure if I have explained the problem well. However, I have found a youtube video of someone demonstrating the issue: http://www.youtube.com/watch?v=48EFXz6xIEU One thing that I did notice is that in the system profiler, it says that there is no display connected before outlining the specs of the monitor but I'm not sure if this is normal or not: Displays: Display Connector: Status: No Display Connected DELL P2411H: Resolution: 1920 x 1080 @ 60 Hz Pixel Depth: 32-Bit Color (ARGB8888) Main Display: Yes Mirror: Off Online: Yes Rotation: Supported I think the problem is caused when the display goes to sleep before the computer does. Is there any way to put the computer to sleep just before the display goes to sleep? Any suggestions as to how to solve this problem would be much appreciated as this display is perfect for my needs otherwise! Thanks!
