I have seen many posts going back over the years from people wanting a script to enable them to view Front Row on a second monitor but with no simple solution. Unfortunately I can’t offer a perfect solution but I recently discovered the application SofaControl (http://www.gravityapps.com/sofacontrol/) which extends the capabilities of the Apple remote and has a menu option to turn on mirroring. It’s still far from perfect but it’s better than nothing if you’re too lazy to walk over to the computer and manually change it each time you want to use Front Row.
Does anyone else have a better solution that doesn’t involve making the secondary monitor the primary?
