Hello together, I was trying to get my Mac’s Apple Cinema Display to work using a CAC-1010-A DisplayPort to Dual Link DVI-D HDCP Off Adapter.
The problem is that the monitor remains black (though it is visibly on since it has a backlight and in fact after a few seconds I can see very faint, multicoloured vertical streaks across the screen.
To make troubleshooting easier, here’s what the overall conditions are:
– The monitor itself works, at least it has just 2 days ago when I used a similar adapter which did display the screen adequately but wasn’t able to make full use of the resolutions otherwise available (that’s why I upgraded to the cable named above in the first place, since it’s specifically designed for the high resolutions of Apple Cinema Display)
– I’ve tried every available DP and USB port necessary for plugging the monitor in, I even tried out of desperation to us a power socket using a phone charger with an USB port to rule out power issues.
– I’ll try to find out the model of the graphic card if that helps, but since the screen is unresponsive I’ll need to find a workaround to access that information.
