MBP & Lion with external monitor crashes!

I have a macbook pro 13'' (2011) and OS X Lion. But the mac crashes every time I try to boot while I use an external monitor.

I only get 2 white screens (on the monitor and on the mac), the fan gets very loud and nothing happens anymore.

The only way to boot is to boot the mac without an external monitor.


It's plugged in via HDMI and an HDMI to mini displayport adapter.

The Monitor is a Samsung Syncmaster XL2370HD.


I hope anyone has a solution for me.

MacBook Pro, Mac OS X (10.7)

I have the same problem. I have MBP 13" and it used to able to hooked up to 23" PHillips Monitor via displayport to VGI. But after installing Lion and after everything connected, my external monitor does not work everytime I close my MBP. Before with S leopard, when I close my MBP and wake the comp using bluetooth keyboard (apple), i was able to wake the MBP and the external monitor displays. But now (Lion) when I close MBP, external monitor shows this error message "Cannot display this video mode, change computer display input to 1280 x 760 @ 60 Hz". Then I opened MBP and I changed the display to 1280 x 760 but when I close MBP, the external monitor shows the same error message.


MBP 13" 2.26Ghz Intel Core 2 Duo with 2 gig of ram.

I've also got an MBP with a Samsung external monitor. It seems to be working for me now (I got it to boot with the external monitor), but I like to use JUST the external monitor when I'm at work. In SL, the clamshell worked just fine -- but with Lion, I keep getting really awful crashes (had to rebuild my Outlook database because of the last one)! It seems to be especially sensitive to Mission Control.


Upgrade from SL, no clean install.
