Q: Can I change display resolution settings on MB Pro for an Ultra HD Monitor?

I have recently bought a Samsung HD U28D590D 4K Monitor but 2011 MB Pro settings are only available up to1680x1050.

 

It detected my Mac monitors higher resolution, but this non-Apple product is like looking at my desktop on a fuzzy TV.

 

Any ideas?

MacBook Pro (15-inch Early 2011), iOS 7.1.2

    Hey nigel272,

     

    I would suggest that you use the following article to help you troubleshoot this issue with your external display resolution:

     

    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.

    How do I select additional resolutions on my display?

    You can use the Display pane of System Preferences to specify how your display works. Not all options appear for all display models. By default the best resolution for your display will already be selected in System Preferences.

    To select a different resolution, use the Scaled option. Some additional resolutions may be available when you hold the Option button.

     

    Keep in mind the technical limitations of your computer with regards to this external display:
