Im trying to mirror the display of a MAC Pro running OSX10.3.8, signal goes to a HD Cinema display 22" at 1900x1200 resolution, and also goes out to a epson data projector (out 2nd video output). I want to have mirrored output BUT alter the resolution of the projection as 1900x1200 on the projection is very hard to read, i want it down to 1024x768. Changing the resolution for the projector output shrinks the viewing area on the monitor dramatically..
Only way i can use independent resolutions is to not mirror the display, however that means i have to drag windows over to the projector to view (this is for a studio/classroom setup) which is no good. Is there a piece of software to enable me to mirror and use different resolutions but still mirror the signal? I've looked at video scalers but they're way too expensive.. Any ideas?
