ARD Screen Sharing is distorted at top and blank on sides

Hi there,

I'm having an issue with screen sharing on Apple Remote Desktop and also screen sharing through the Finder.

When I screen share with a Mac Pro which is connected to a projector the screen share looks like the image below:

The top is distorted and there is a large black bar to the right.

Would this have something to do with the screen resolution or interferrence between the Mac Pro monitor and the attached Projector?

This issue occurs even when the Projector is turned off.

Also, the mouse is not correctly lined up on the screen share, so to click on a text box I need to click a bit above the top of the text box.

The Mac Pro is part of a Mac Pro suite of 17 Mac Pros and I am having the same issue connecting to the troublesome Mac from all of the Mac Pros in the room. However, there is no problem connecting to a screen from the troublesome Mac. In this case, the image is fine.

The Mac Pro is a Mac Pro5,1 2.8QCX/10GB RAM/1TB/5779/SD (mid 2010). It is connected to a EIZO FlexScan S2202W LCD monitor and Hitachi ED-X42 projector. We're running Mac OS X 10.7.1.

The Mac Pros are all connected via ethernet on a Local Area Network.

All Apple and ARD software is up to date.

Any help with this issue is much appreciated.

Thank you!

Lawrence

Mac Pro suite, Mac OS X (10.7.1)

In the ARD preferences, on the Control & Observe section, have you tried switching from "Show full size" to "Scale to fit available space" or changing to bottom option for "Display in new window" or "Display full screen"?

I have the same issue, but I only use screen sharing, not ARD. Screen Sharing preferences are pretty limited, but I tried a few things like full screen and toggling scaling with no change. I see a distorted bar at the top of the screen that appears to be the bottom of the screen repeated and the mouse vertical tracking is off. It makes screen sharing unusable for me..

Hi Brandon and slepping, thanks for the advice. Unfortunately none of your suggestions worked for me.

However, I think I've solved it!

I think it's to do with synchronising the screen resolutions of the monitor and projector.

Originally my projector resolution was set much higher than my monitor resolution.

I've lowered my projector resolution to the same resolution as the monitor and the screen sharing works much better now. Check the image below:

I'm sure I didn't have this issue in Mac OS 10.5 and 10.6. But hey ho, maybe a niggling bug that needs to be ironed out in Lion.

Thanks for all of your suggestions.
