Currently Being ModeratedNov 24, 2006 6:47 AM (in response to club152)So when the lid is open the 20" Cinema has an image on it? In that case, the missing step is that the notebook must be plugged into the AC adapter.
Currently Being ModeratedNov 24, 2006 7:06 AM (in response to BSteely)Yes..there is picture on the 20" cinema screen when the laptop is opened and the power cord is plugged in. But as soon as I close it....the screen goes blank.
Is there a setting that I missed??Powerbook G4, Mac OS X (10.3.8)

Currently Being ModeratedNov 27, 2006 10:22 AM (in response to Malcolm Rayfield)I'm following this disscussion as I have the same issue. I tried your suggestion of plugging a mouse and a keyboard into the new macbookpro but, with the lid shut, the 20" cinema display remains black.
Any other suggestions?
Furthermore, I notice that the screen resolution is poor. I have another 20" display in the office - that one plugged into a G4 tower and it shows far better resolution. I've got this new 20" display on the highest resolution settings.Mac Book Pro 15", Mac OS X (10.4.8)
