[QUOTE="DMIrishFlyer, post: 1455926, member: 276437"] Hi guys - first post, first question! Go a early 2011 MACBook Pro with 16GB memory running OS10.8. I have two dell P2312H one running from a display link adaptor (with MAC v1.8 driver) All is good when I'm powered up and connected to the displays but when i undock (i'm using a hengedock) it thinks the monitors are still there. When i reboot, every time its boots up to a gray screen (not the apple logo screen but the grayscale patterned screen) - so it boots OK but seems to think that it still has the external monitors attached.... the only way i can fix it is to do a PRAM reset - every time I power down and up. The PRAM reset works but its driving me nuts... Anyone got any ideas? it would be very much appreciated. thanks D [/QUOTE]
