I have rather a strange issue when I try to connect a dell monitor to MacBook Pro. Firstly the Dell monitor won't detect the signal from MacBook if I connect it immediately after the laptop is booted. It takes a while (I didn't measure how long) for the monitor to detect the signal from MacBook after lot of attempts.
This is not the end of the problem. If I want to log in back after my MacBook goes to sleep mode, then it won't wake up. I have to disconnect it from the Dell monitor in order to log in back, worst of all sometimes I need to force shutdown the MacBook to log in back.
I am using a DVI connector from Monoprice to connect the Dell monitor to my MacBook.
What could be the issue? Any help is appreciated.
