The New MacBook Pros have 2 graphics cards. When I get the DisplayID, the
slow card and fast card differ by 2... ie:
Fast card DisplayID 1234567
Slow card DisplayID 1234565
(not real numbers)
After switching modes in the Energy System Pref Pane, calls to get the
DisplayID return the correct results, but the desktop Pref Pane seems to
still be using the old IDs... Ie if I just switched from slow to fast, the
IDs used by the desktop pref pane are still the slow IDs... But it works to
update the desktop.
Is there a way on these machines to get the ID for both cards although only
one is running at any given time?
I hate to assume it is always going to be "off by 2" although this is true
for both the internal 15" and the external 24" LED.
Thanks,
Trygve
