I have just purchased a thunderbolt->hdmi cable in order to connect my new 2011 macbook air to a samsung monitor i have. However, after setting everything up and recalibrating the screen with the macbook air, greens look a lot brighter than they should. is there something wrong with my calibration? the cable? my monitor? assuming the mba's built in screen has fairly accurate color representation i have taken 2 pictures comparing the mba air screen and the external monitor. hopefully my crappy iphone camera can give you some idea of the problem i'm experiencing. can anyone help? thanks!
