Re: DisplayLink setup on macbook pro fails...

hi,

I'm checking the list of available Displays using the following code:

int maxDisplays = 2;

CGDirectDisplayID onlineDisplayIDs[maxDisplays];

CGDisplayCount displayCount;

CGGetOnlineDisplayList(maxDisplays, onlineDisplayIDs, &displayCount);

printf("displayCount is %d ", displayCount);

CVReturn res = CVDisplayLinkCreateWithCGDisplay(onlineDisplayIDs[0], &_displayLink);

if(res == kCVReturnSuccess) {

CVDisplayLinkSetOutputCallback(_displayLink, _displayLinkCallBack, self);

}

else {

_displayLink = NULL;

printf("failed");

}

as expected, I get a displaycount of 2, if I have another display attached to my macbook pro, respectively 1 if not, so I assume I did this right.

res has always a value of -6670 - it doesn't matter which display I select.

The macbook pro is the 1.83/128mb GRAM model, with 10.4.6 and qt 7.1

What can I do? Who can reproduce the problem on another intel mac?

Thanks
