We are having schoolwide issues with our
ActivBoard 378 Pros since upgrading our MacBook Pros to Yosemite (10.10.5).
We have been using a projector setting of 1024×768, 70 HZ which was
perfect for both the ActivBoard and display setting on the MacBook. That option
is no longer available to us, and none of the 3 display settings fit well on
the board, and the on screen display on the Macbook is tiny. Please help!
