    Hey there 7tk,

     

    It sounds like you are unable to see any video on your external monitor connected to your MacBook Pro with an HDMI to MiniDV connector. I would use the troubleshooting steps from the following article to help troubleshoot the issue, named:

     

    Apple computers: Troubleshooting issues with video on internal or external displays

    http://support.apple.com/kb/HT1573

    No video or no signal, image distortion, "snow," or flickering

    Check connections

    When using an external display be sure to check the following:

    1. If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
    2. Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
    3. Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
    4. Try unplugging the video adapter or cable and then plug it back in.
    5. If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
      • Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
    6. If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).

    Reset the system

    You can reset the Mac's parameter RAM and SMC.

    Reset the resolution

    Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:

    1. Start up in Safe Mode.
    2. From the Apple () menu, choose System Preferences.
    3. Choose Displays from the View menu to open the preferences pane.
    4. Select any resolution and refresh rate that your display supports.
    5. Restart your computer.

     

    Thank you for using Apple Support Communities.

    All the very best,

    Sterling

    I bought the same Hewlett Packard Pavilion 22xi connected via DVI port - Miniport to a MacBook Pro , OSX 10.9.5 but I have a resolution problem. The screen is like "zoomed" in and part of the OS X desktop are out of the monitor surface. Using the "underscan" feature to "maximum" the resolution changes but the images are fuzzy, not clear.

    Make sure Mirrpring is off in the Arrangement tab of Displays system preference.

     

    See if there are picture size controls on the HP display.  You want a 100%, fit-to-screen, or pixel-to-pixel settings.

    Hi 7tk

     

    I had the same problem and was about to follow the instruction re restarting in Safemode and was looking a back of monitor for resolution spec when I spotted small black button at the bottom centre behind screen stand - so pushed this whilst connected to macbook pro and hey presto!
