When my W520 (Win2008R2) power management profile shuts the display off (after 10 mins, for example), the externally DVI connected screen no longer receives a signal, but the screen doesn’t go into power saving mode. Instead, the monitor stays powered on (the green power light normally turns yellow), and displays the message “Cannot display this mode”. It’s a Dell monitor, and this message appears to be a Dell message, nothing from the Lenovo or Windows.
It’s a new W520, and a new docking station – the ThinkPad Mini Dock Series 3 170W. The previous W510 and previous docking station ThinkPad Mini Dock Series 3 135W both worked fine with this monitor, and were able properly stop sending it a signal.
So…where do I start troubleshooting? Is this a Lenovo docking station issue? Are others having this problem?

Thanks for the reply. I just finished testing with a different (brand new) monitor, and it seems to work as designed. All good - seems to have been an issue with the old monitor I had.
