Q: After upgrade to Mavericks, AppleTV no longer mirrors my mid-2012 Macbook Pro's accessibility zooming.
Prior to Mavericks upgrade, I had accessibilty zooming enabled using the control hotkey with two-finger scroll.
The zoom effect would be duplicated in AppleTV and transmitted to an overhead projector in my classroom.
This feature is very useful for directing student's attention to a particular region of the screen.
However after the upgrade, AppleTV no longer mirrors the zooming effect.
I can see the zoom on the laptop, just not on my projector.
I can see zooming on the projector if I use the VGA adapter and plug directly into projector.
Laptop:
mid-2012 Macbook Pro
OS X 10.9
8gb RAM
2.3 GHz Intel Core i7
Have tried variety of displays settings and none work including:
--selecting best for display or AppleTV
--changing the resolution
AppleTV
model: MD199LL/A
software: 6.0 (6646.65)
resolution: 1024x768 60hz (my projector requires this)
Projector:
HP vp6320
I use an HDMI to VGA/Audio adapter to convert to VGA for my projector.
I seem to recall that overscan correction was an option to set under Mountain Lion, but I can't find that when doing a Spotlight search in System Preferences. Not sure if that would help or not but thought I'd mention it.
Any help would be greatly appreciated.
