Thank you so much! Finally mirroring works 100% on my Netbook with GMA950 DeviceID: 27AE

You have really helped me with posting this, before i had just a striped screen when trying to mirror the screen to an external monitor, now it works on all resolutions!

You are the best!!!

Finally my laptop works as it must be.

But my monitor works like a additional screen, not mirror - it is more than I ever want.

Lion, 10.7.5, Toshiba Satellite A100-811.

 

Some little issue - bottom side of the screen (only ext.Monitor), about half of Dock bar height, is like a scratches or scrambled (trying to solve on this method). That happens only when I use resolution higher than 1024x768x32 75Hz.

On the resolution 1024x768x32 75Hz and below, there is no problem.

Though the main screen of laptop has no problem (but I didn't try to change resolution on it, not needed).

On the 10.6.8 in the same resolution I hadn't such problem.
