    I am trying to connect my Macbook Pro (Mac OS X - Version 10.7.4) to a Samsung SyncMaster S20B300 monitor.

    As soon as I connect the minidisplay port into the monitor, it turns it off (puts it in sleep mode - on/off button flashes).

    Andy advise how to get this to work?

    Thanks

    Try going to System Preferences -> Displays

    From there try Detect Displays or Arrangement to get the monitor to work.

    If this does not help, make sure the input on your external monitor is set to what ever type of connection you are using, i.e. VGA or DVI or HDMI. Oblivious check and make sure the connections are not loose too.

  • Questioner

    I have a new macBook Pro 13" and a 30" apple monitor. I am connecting this monitor via a DVI, and am unable to retrieve a list of all the supported resolutions for the 30" monitor. The Mac book only allows be the same resolution range as its built in screen. How can I change the resolution on the Mac Book to increase the resolution on the 30" external monitor.

    Thanks,

    Have you tried going to System Preferences -> Display? When you have the 30" display plugged in, there should be an Arrangement tab, where you can uncheck the Mirror Displays setting. This should give you access to the resolutions of the 30" display.

    Are you using the Mini DisplayPort to DVI or the Mini DisplayPort to Dual Link DVI port? The standard DVI adapter won't be able to run the full resolution of a 30" monitor, and you'll require the more expensive Mini Display Port to Dual Link DVI adapter to use the full 2560x1600 resolution.
