My 2010 iMac's display shows up distorted lines on start up then gets stuck at the gray Apple logo screen. After being stuck there for a while it then reboots itself and does the same process over again until I force shutdown. Fortunately I have a MacBook Pro in which I can use to boot from and view the files from my iMac this way. I believe my iMac is having graphics issues but I have an external monitor I would like to use to view my iMac. Is it possible to configure the settings for my iMac from my MacBook Pro so that I can set my iMac to display via the external monitor and if not are there any alternatives?
Thanks in advance!
