Though the steps vary for Mac and PC units, it is fairly easy to connect two monitors to one computer.

  1. Attach the monitor
  2. Physically attach the second screen to the main computer. Most modern units make this process simple. Users simply locate the different video output ports, usually VGA and/or DVI, and then attach each monitor with the appropriate cable. Which ports and cables to use are specific to the computer model and display screens. Users should read each unit's manual to determine the proper combination. After hooking up the monitor, follow the specific directions for a Mac or PC unit.

  3. For PCs
  4. If a computer runs the Windows 7 operating system or later, it should immediately recognize the second monitor upon startup and prompt the user to configure the new monitor. If this does not take place, users can access the same setup options through the Control Panel by clicking on "Display" and then "Connect to an external display."

  5. For Macs
  6. Apple OS X operating systems should also instantly recognize a new monitor hookup and prompt users to configure the new monitor. However, if this does not happen, users can access the configuration by clicking the "Detect Displays" button in the "Displays" menu or putting their computer into sleep mode and then waking it up.

  7. Configure the computers
  8. Once within the PC or Mac display menu, users can configure their monitors by selecting their preferences for display, resolution and orientation. At this point, they can also choose to use the two monitors as an extended display, duplicate or mirrored displays or displaying the desktop on only one monitor.
