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.

    Same problem. Zoomed image will not show on the Apple TV screen even though it does show on your laptop or desktop.

     

    I tried every aspect of System Preferences>Displays and Accessibility. None worked. Problem was presented to an Apple Specialist on his Mavericks computers and his Apple TV. Same thing. He said this appears to be a Mavericks glich and immediately went to transmit the problem to Cupertino.

     

    A poor "work around" is to use System Preferences>Accessibility and under Zoom, select Zoom Style "Picture-inPicture" which will result in a "zoom box." The box can be scaled to a desired size and activated with the Control-Scroll motion. This box will display zoomed on the Apple TV screen. The default Zoom Style selection "Fullscreen" did not and will not show on the Apple TV screen even though it does show on your laptop or desktop

     

    The problem: the zoomed "magnified" image loses resolution and if zoomed far enough, becomes "pixilated."

     

     Apple needs to fix this or tell us how to go back to the earlier Control-Zoom which I think the "Fullscreen" was intended.

    Thanks for the response MacVA.

     

    Since my post I also have decided that this is a Mavericks issue and not an Apple TV one.

     

    (I tested a non-Mavericks laptop on the same Apple TV v.6.01 and the accessibility zooming worked fine.)

     

    From what I've been reading, I think the changes Apple made to address other multiple monitor issues may have (temporarily, I hope) broken this feature.

     

    I also noticed the picture-in-a-picture feature when I was troubleshooting, but fortunately I do have a long enough VGA extension cord to reach my laptop, so I've given up on using Apple TV for now until a fix comes.

    Thanks again for your workaround, MacVA.

     

    Still waiting on an OS update, so sometimes I will use your workaround.

    Figured I'd post some more detailed instructions for those interested:

     

    Accessibility > Zoom

    Check: Use scroll gesture with modifer keys to zoom > ^ Control [or whichever key you want]

    Check: Smooth images

    Zoom style: Picture-in-picture

    More options > Adjust size and Location

    Click/grab window corners/sides > resize to fill screen

    Click "Ok" to exit resizing

    AirParrot still does magnify mirrored fullscreen onto ATV 3 as expected in Mavericks. I've kept it on my system for that sole purpose.

    Thanks Max!

     

    AirParrot does indeed work.

     

    I should note, however, that my TRIAL version of AirParrot did NOT mirror the fullscreen effect at first so I went ahead and purchased the full version (although I'm not certain that I had to do that) AND had to update the AirParrot video driver (I was prompted to do so when running AirParrot for first time) before it would mirror the fullscreen correctly.

     

    Most importantly, AirParrot does work while AirPlay still does not.

     

    I also updated my ATV3 to latest version (6.0.2) as well.
