Do you want to supersize your MacBook Pro’s screen for your working or for your gaming need? Adding it to an external display would be the right thing to do. Don’t be scared, this is an easy thing to do. You will be able to do this efficaciously if you follow the steps given below.

  1. Connect the External Display

You can connect the external display to the MacBook Pro using Mini DisplayPort, HDMI, DVI, Micro-DVI, Mini-DVI, and Thunderbolt. The process with each of them is the same. Just connect the MacBook to the external display with the necessary adapters and cables. Power on the monitor, Mac detects the external monitor, automatically. It serves as an extended desktop.

In case the MacBook doesn’t recognize the external display, open System Preferences. Here, you will find Display Setting Options. Tap on ‘Detect Displays’ and hold the key for making changes in it. This will make the external display function adequately. 

If the external display still isn’t detected, check if the cables are well-connected and the monitor is on. When it still doesn’t work, know that something is wrong with the connectors.

  1. Set Monitor as Primary Desktop

When you get the additional monitor detected, you might want to use it as the primary desktop. This means that the dock, desktop, and menu bar are being displayed on the additional monitor. For doing this, go to “Display” and then the sub-menu Arrangement, you will find a small white color menu bar over the desktop window of MAC to the thumbnail of the external monitor. The two screens will be set to a new configuration.

  1. Adjust Display Resolution

To adjust the resolution of the added monitor, alter it to suitable scaled version. However, keeping it on default is always the best option. In case you are unsure, simply stick to it. Check if the Display is selected on the external screen then change it to Scaled from Default for Display for selecting the resolution you prefer.

  1. Rotating Display

Some people would like to have the second display in a vertical position. If the monitor that you have connected can rotate in between landscape and vertical orientation, and you would like to get the vertical look, ensure that you have the right setting for this. Check if the Display setting is selected on the external monitor. Now, rotate as per your preference.

  1. Mirror Displays

If you want, you can opt for Mirror Display. This way the external display will show the things that are appearing on your MacBook Pro screen. While the video mirrors, the MacBook will try using the same resolution or even the closest resolution from the built-in display to adjust to the external monitor.

  1. Use MacBook with Lid Closed

In case what you want is just a bigger display, you will be able to do so with the use of the clamshell mode. For doing this, you will have to connect the MacBook to the power adapter. Also, you are going to require an external mouse and keyboard. When using a wired mouse and keyboard, make sure that these are connected. Now, just close the MacBook lid. The desktop will appear automatically on the monitor following a blue flush. However, if you are using Snow Leopard or a version older than that, click on the mouse button or press a key for seeing the desktop.

For the Bluetooth device, the same thing is applicable. Check if they are paired and then check if the settings are right. Go to Preference, then Bluetooth, and tap on advanced for this.
