Digital video doesn't work
Suddenly my second digital monitor is black. I think the problem is the monitor as id I use a VGA adaptor in the VGA in of the same monitor it's ok. Later O try another digital monitor, it show the image, few seconds, than black. I suppose the Mac is over. I run the Hardware test and it reports the error: 4VDC/I/40000003 Video controller.
I connect the mac and the digital monitor with another cable, and now it seems to work. Th first cable is a DVI to HDMI; the last one is DVI to DVI. Eventually is it possible to change the video controller? Thanks
Is this a good question?
