I have a new PowerBook pro and want to connect a second monitor. I have a 21" Samsung monitor with both a HDMI and a VGA connection. I currently have an Apple mini port adapter that I used for connecting my previous MacBook pro to my monitor.  Can I use it to connect to my thunderbolt port or do I need a thunderbolt to VGA adapter.  Second is it better to use thunderbolt port or HDMI port to connect my monitor?

Thanks in advance for your replies.

MacBook Pro with Retina display, OS X Mavericks (10.9), Aperture 3.4.3

    First off, I assume you mean MacBook Pro, not "PowerBook pro".


    Might as well use the HDMI connection since all you need is the cable on this computer.  That's what I would do.


    If you want to use the Thunderbolt port (which includes all the DisplayPort connections), you will need an adapter.  Your old computer vintage will determine if the adapter is useable on your new computer.  The Thunderbolt port will accept a mini-DisplayPort plug.

    Using HDMI by default from a MacBook Pro to external monitor actually displays the wrong color profile (In short your MacBook Pro thinks that the monitor is a TV)... It can be fixed and over written to look great though and just using an HDMI cable is smaller and more streamlined than a thunderboldt (or mini display port) to VGA or DVI adaptor. HDMI and DVI are always better quality than VGA.

    Thanks for your response.  I have had three monitors connected (HDMI) to my late 2013 MacBook Pro running Mavericks 10.9.1 The first was an older Samsung (PA2370) that worked fine, great picture.  I then ordered a Dell U2413 that gave me a horrible picture.  It showed many of the symptoms described in the above discusion by  Mathew Inkson.  I called Dell and after 2 hours of talking with tech's who seemed to know less than i did, I was finally told that Model U 2413 was not compatable with my Mac.  I retured that monitor and began a new search for a new monitor that was good for photography editing and that was compatable with Mac.  I ordered a new Asus PA249Q and it seems to be working well with my MacBook pro HDMI connection.


    So now I am confused?  Am I not getting the correct color space to run my monitor even though it looks as good or better than my previous Samsung.  Shoud I apply the fix from the above article or has this problem been fixed in 10.9.1.  If I apply the fix and it doesn't work or makes my monitor look worse, can i go back to original setting.

    I want to be sure I am getting the full power of my new monitor.

    Yeah... just make sure you don't over write the color profile file (if its the same name as the file you are copying over, make a duplicate of the original so you can copy it back if things aren't right). If it doesn't look right, just delete the color profile that you added to the folder.
