When it goes green the on/off button does not turn off when pressed. The monitor may come on after 20-30 mins and then its ok..even when you restart the pc. Thanks Simon PS . when the pc is first turn on the monitor says not connected going into power save mode.

Need a faster answer?
Maybe update your display drivers. PC appears to be slow.
Make sure you don't have a bunch of apps that auto start.
Do you hibenate your PC?
Same issue if you connect monitor to another PC?
If issue follows you to a different PC it says monitor. If it doesn't it says the first PC (that monitor is currently connected to) had a cpu/memory or a driver issue.

Good luck
