imac Mavericks external display not outputting at 1080 only 720

My display works fine on say xbox 360 at 1080p... but imac will only recognise it on 720 ...I have a mini display to VGA cable and even when i hold option on system prefrences > scaled still no luck. Reading forums people are having same trouble. Is is a bug?? workaround?? update fix due?? Anybody please it is driving me crazy this is a big thing for professionals who need multi screen outputs

iMac, OS X Mavericks (10.9.1), 8 Gig, 2,5 Ghz
