This isn't a major problem, just something that's a bit annoying. I've got a MBP 17" running 10.8.4. I recently allowed a friend to use it connected to a Canon projector for a camera club presentation. His projector displays at 1400 x 1050 and, when connected it cut my laptop screen down to that resolution with black bars either side. Not a problem for the presentation but now, every time I start the laptop up, it boots with a 4:3 aspect ratio then switches to full screen after a little while.
In System Preferences/Display, I have it set to "best for built-in display" but it makes no difference. I was wondering if anyone knew if there was either something I could do in Terminal or if there is a Preferences file I could 'dump' to stop this happening.
As I say, not a major issue but a little infuriating and I'm getting a lot of earache from the missus who uses the laptop a lot - to the extent she thinks she owns it
Any advice greatly appreciated.
