I have just tried to link a 20" Cinema Display to a Cube, using the Belkin DVI-ADC adaptor, but the monitor remains blank. However, on restarting the Cube, the monitor shows the startup screen (grey, dark grey apple, progress circle), all looking fine. So the monitor is working and the adaptor is working. But then the screen goes black as the Cube goes to display the next screen in the startup process. Any suggestions? -- Jan A.
