[QUOTE="wmprice1240, post: 891751, member: 99551"] One thing to try, when the issue happens go to SystemPreferences->Displays You will see the current resolution in the list on the left. It definitely sounds like the display is not being recognized when the computer starts. I see this when I am connected to my KVM switch. When you get into this state you can simply click the 'Detect Displays' button on the right and things should go back to normal. Strange that it's happening on the laptop as well. Can you verify that the laptop is not connected to your display when it happens? Also, can you consistently reproduce the problem by forcing the laptop to sleep and then waking it up again. Here's something I would try: 1) Disconnect the laptop from your display completely 2) Make any adjustments necessary to get the laptop display correct (when you disconnect, this may require you to go back and click the 'Detetct Displays' button. 3) Put the laptop to sleep. 4) Wake it up. This will eliminate the external display option and tell you if it's something with the video card and not the external connection. [/QUOTE]
