Hi there,

 

Since I upgraded to Mountain Lion I am getting intermittent, rapid horizontal screen shifts on my 24" CinemaLED Display with my new 15" MacBook Pro. The 24" CinemaLED is attached via Thunderbolt Port and Pegasus R12. I don't have that problem with a older MY 11 17" MBP.

 

Anyone else having that problem? I tried to fix the problem with disabling graphics mode switching in energy saving control panel.

 

And no, I don't want to buy the 27" TB Display. I had that before but switched back to 24". 20 years of IT have done no good to my eyes, the 24" resolution is a easier for me to read and work with, unless OSX offers adjustable font sizes for Applications.

 

Cheers
