When I bought the Mac Mini I knew that it didn’t support Dual Screen but that it was possible to connect two screens via a DVI splitter device, which would allow you to run two screens in mirror mode.
I can connect the screen directly to my Mac Mini and it works perfectly. I can connect the DVI adapter to my Mac Mini and to my TV via an s-cable and it works perfectly.
I have bought a 2 Port DVI Splitter, but this is where I start to have a problem. If I connect the splitter to the Mac Mini and connect the screen to the splitter the screen works perfectly – so far so good. BUT when I connect the DVI to Video adapter to the splitter, zilch. The screen still works but I don’t get anything on the TV.
I have tried the screen connected to both ports on the splitter and it works on both, so I know that both ports are working fine on the splitter. I have followed the splitter instructions to the letter i.e. connect the screens, then connect the splitter to the Mac Mini, then power up the splitter and then finally power up the Mac Mini, so I can’t see what the problem is.
Logic tells me that there must be something different between the port on the back of the Mac Mini which allows the DVI to Video adapter to connect and work, and the ports on the back of the splitter. I have just read this on the Apple site under the description of the DVI to Video Adapter:
“The Apple DVI to Video Adapter is designed to work with the DVI port on the MacBook Pro, Mac mini and Power Mac G5 systems only.
Use a separate DVI to VGA Adapter for VGA video out for MacBook Pro, Mac mini or Power Mac G5 (included with all MacBook Pro, Mac mini or Power Mac G5 systems or available for order as a standalone kit). ”
At the moment the workaround is to disconnect the splitter from the Mac Mini and plug in the DVI to Video adapter each time that I want to hook up to the TV, but this is a little fiddley given the inevitable amount of cables at the back of my desk, and not ideal in that the TV is in another room so I can’t actually see the screen (all I want to do is watch a movie that I have recorded to the Mac Mini so this set up is actually not as mad as it seems) so need to take my wireless mighty mouse through with me to control the screen, which is actually a pretty cool thing to do. Another down side is that as I have a number of things hooked up to the USB and Firewire ports on the Screen daisy chained through the Mac Mini and the LaCie external drive and hub, when I unplug the screen I effectively removed devices and they don’t always reconnect straight off when I reconnect the screen.
So I really would appreciate any suggestions on how to work around this problem. Maybe I need a more “powerful” splitter, or another type of converter/adapter?
