    Hey there jamie0105,

     

    It sounds like your external monitor is not funcitoning correctly with the computer after updating to Mavericks even after reseating your HDMI cable. I recommend these troubleshooting steps from the article named:

     

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

    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
