In this guide, I will detail how to change the screen display type between "extend" mode and "duplicate" mode for desktop PCs with multiple monitors and or with a projector. All necessary clicks are highlighted in red to make it easier to navigate and follow along!

How to change display type in Windows 10

Step 1: Access the start menu

• To begin, open the "start" menu in the corner of your screen.

Step 2: Select the settings option

• Select the "gear" icon which appears slightly above to open the settings menu.

Step 3: Click on the "System" option

• When the settings window opens up, select "System".

Step 4: Select display options

• By default the "Display" option should be selected. If not please select "Display" now.
• Scroll down near to the bottom of the right panel until you reach "Multiple displays" and select the drop down box.

Step 4: Select which display type you would prefer

• Finally, you can now select which display type you prefer. The two types are detailed below:
• "Extend these displays"
  • This option makes it so that both screens are separate, and you can move your mouse between them by moving your cursor or any open programs to the edge of the screen closest to the other screen. IE: Moving your cursor to the right edge to access a screen that is on your right and vice versa.
• "Duplicate these displays"
  • This option is most common for projectors as it makes the screen exactly the same on both displays. However be careful when it comes to viewing sensitive data such as SIMS.
  • Make sure to "Freeze" your projector before using these systems as duplicating means everything is visible on both screens at once.

Once you have selected whichever type you like, make sure to press keep changes and then you are all done! Simply close the settings window and return to whatever you need! And if you are still struggling, don't forget to drop a ticket through the IT portal or send an email to it@crst.org.uk and a technician will assist you!
