About 15 display modes are available, some marked interlaced, some
marked
stretched, and some plain. From what I understand, those marked
interlaced
or stretched are using TV mode, and those unmarked are standard
computer
resolutions over DVI - well something like that anyway.
If a quartz composition is played using the Quartz Composer Player
Example
code, when in one of the interlaced or stretched modes, the screen
becomes
corrupted. Furthermore, playing an iPhoto 5 slideshow in one of these
resolutions has the same screen corruption problem.
It might be a VRAM issue: try modifying the Player sample code and
disable that line in -applicationDidFinishLaunching
