Hi, When i connect my Early 2011 MBP to an external display i get a garbled display at startup. I then have to disconnect the hdmi cable to the external monitor, after which the display clears up (on the laptop) and then when i reconnect the external monitor, it works fine. The problem with this process is that i have to do it each time i start/boot my laptop with the external display connected. The display mode is currently set to mirror displays if that helps. Would appreciate any advice users with this kind of set up can provide. Thank you in advance.
