Still having this weird problem
When I boot up the mac mini I see the grey screen and the apple logo without any problem.
When I enter the blue screen and later login, there is a artifact on the left side of the screen about 5-10 pixels wide which is changing colours rapidly on each pixel / line
I think I can rule out any kind of interference since it works on some resolutions.
It seems to be related to aspect ratio since 800 x 600, 1024 x 768 works but all other which is not 4:3 is giving the artifact.
Is there some kind of setting I can change, maybe in the screen settings for beovision-4?
If there is a similar setting / program on the mac mini help is really appreciated
Since it oddly dont appear on when connecting the macbook to the beovision screen I am really scratching my head here...
