Samsung monitor not working with Macbook Pro

The MacBook Pro can be connected to a secondary monitor if your computer has one or more video output connections, such as VGA, DVI, HDMI, or DisplayPort. Almost all Samsung monitors can be connected to Mac pro computers that support compatible video interfaces. Connecting Samsung monitors with Mac or Windows computers can simply take a suitable video cable. If you do not know the cable that you need, you may wish to check the documentation provided by MacBook Pro and Samsung.

If you are facing the issue “Samsung monitor not working with MacBook pro,” follow the following steps to try again.

Your MacBook Pro must be turned off, and you should point it in such a way that you can see the video connection. The power cord for the Samsung monitor needs to be plugged into an electrical outlet, and the video cable needs to be connected to the monitor’s video input. The majority of monitors have either a connection on the back or underside of the screen that permits you to connect them.

The video cable from your Samsung monitor should point directly at your MacBook Pro, and the other end of the cable should be connected to the video out connection on the Mac. This connection can be found on either the panel’s left side or right side.

Now, you will need to turn on the MacBook Pro and then navigate to system preferences on both the Samsung monitor and MacBook Pro.

Choose a resolution for your display using the Display section. Then select the “Arrangement” tab and, using the dialog box, drag your screens around the screen alignment area to configure the alignment of the screens. You can display a mirror image of the main display on your Samsung monitor by selecting the “Mirror Displays” checkbox.


I would recommend that you disconnect and reconnect the cable if you have an external display connected to your Mac. The only way to connect your external display to your Mac is using a Thunderbolt or USB-C adapter if it cannot be connected to your Mac through its ports. Assuming you are using a USB-C or Thunderbolt adapter, then the display adapter must be compatible with DisplayPort Alt Mode / Thunderbolt / USB 4 if you are connecting a display via an adapter.

Must Check No. of Displays

The Tech Specs page on your MacBook Pro will provide information about how many external displays it supports. It would help if you looked at the number of displays because sometimes it is set to 0 or less than the displays you want to connect simultaneously.

  • After selecting the Apple Logo menu, then About This Mac, then pressing Command-C, you can copy your serial number.
  • When you click the Search Tech Specs button on the Tech Specs page, type in the serial number of your computer in Command-V, then click the Search button.
  • The technical specifications for your Mac can be found by clicking on the “Specs Page.” The number of displays your Mac supports will be listed under the section “Video Support” or “Graphics.”
