NSScreen + resolution change

Subject: NSScreen + resolution change

Hi,

I have an kiosk-type application that optionally changes the resolution via CGDisplaySwitchToMode and then goes full-screen

Unfortunately [[NSScreen mainScreen] frame] (et al.) continues to return the pre resolution switch values. The problem is that in Cocoa origin.y seems to get shifted during the resolution change, probably due to the top-left origin coordinate system in Quartz. I.e. changing the resolution results in an display coordinate system moving [0,0,1280,800] -> [0,32,1024,768].

Is there a way to get up-to-date values instead of relying on an deltaY shift?

TIA,
	Tom_E
