Dual monitors, also known as multi-monitor, multi-head, and multi display, are when you use several display devices, such as monitors, televisions, and projectors in order to augment the available area for a computer program running on a single computer system.

It has been proven, through extensive research, that the use of dual monitors or dual-display systems increases the rate of productivity by almost 60-70%. Because of its ability to enhance productivity, it has gained quite a bit of recognition among super shops and hotels where the second display is used for transparency and to interact with the customers.

One problem that obstacles this user-friendly innovation is the mirroring of these dual screens. This is when the monitor on the external display is duplicated by the computer monitor and you see the same picture or view on both the desktop and projector.

Mac and Windows computers have two different display modes when connected to an external display system. Disabling the mirroring of dual monitors varies slightly in their processes depending on whether it is Mac or Windows.

How to stop dual monitors from mirroring on Mac

For a PC, disabling display mirroring can be done in two simple steps. Firstly, you have to open your “Display settings” through the control panel. You can also do this by right clicking the desktop and choosing “Screen Resolution”.

Next, you’ll have to go to the “Multiple Displays drop-down” and look for the option titled “Extend Desktop to this display”. By selecting this option, you will be able to disable mirroring on your PC.

It is fairly similar to MAC. You begin by opening the “System Preferences” and then select “System Displays”. Then, you only have to select “Arrangements” and Uncheck “Mirror Displays”. For a MacBook Pro, you would have to open the “Control Center” and tap the “Screen Mirroring” option and click on “Stop Mirroring” at the bottom of the window that opens up.

Tips on how to fix multiple monitors on your MAC.

To begin with, you should always double-check your connections. Though this might sound insignificant, but sometimes the simplest of problems cause distress. For instance, if you’re using a HDMI to Thunderbolt 3 port in, the sequence in which you plug it in is very important; plugging it in the other way around can lead to problems.

Moreover, you need to check the cables too, as we are on the topic of “checking”. In case you’re using bargain-bin-cables, it is especially worth checking. Perhaps you have a functioning HDMI cable, but it could be too old to support the resolution you’re aiming for. Though this is not a commonly seen scenario, it doesn’t hurt to be careful now, does it?

Secondly, you should refrain from using Thunderbolt 3 dock. These are helpful in case you have a recent MacBook model as instead of plugging in two or three dongles alongside your power supply point when you want to hook up your external monitors, you can just plug in one connection.

Thirdly, check your adapters and make sure you’re powered up. According to the MacBook model and monitor you are using, the computer may not have enough backup to connect from the monitor to the battery. In order to fix this, you’ll have to plug in your laptop wherever you are using it with your monitors.

Furthermore, check the display with another computer and try adjusting your resolution. Checking it with another computer allows you to surely find out if your monitors are working perfectly. One of the most common problems is blurry-looking points which are due to incorrect resolution.

This problem can be manually fixed by opening “System Preferences” and going to “Displays” on the second row. Next, you have to hold the option key while selecting the “Scaled” option which will reveal a full list of resolutions to try.

Lastly, just click on “Ok” to apply the changes and close the window. This process is fairly simple and mostly similar for Windows 7 to Windows 11. Some users complain that their USB monitor is mirroring their laptop monitor or that their monitor is upside down.

To solve the upside-down issues for Windows users, you will have to click on the second screen icon. This will open the orientation drop-down box from where you’ll change from “Landscape” to “Landscape (flipped)”.

After that, click apply and move your second display icon from right to left of the first display by simply “Drag and Drop” it. Click apply to finish the setting of the lay out.

What is the difference between mirroring, spanning, and extending monitors?

In simple terms, mirroring monitors is when you see the same thing on both the monitors whereas spanning monitors mean that your computer is able to interpret all the other monitors that are spanning as one giant monitor. Different things can be seen on each of the monitors and the task bar; Start Menu and background are stretched across all the monitors.

On the contrary, your computer interprets the monitors that you are extending, as separate devices, is known as “Extending monitors”. In this case, different things can be seen on different monitors and the desktop background will be displayed on each monitor.

How do you disconnect a screen on a dual-monitor setup?

You will be able to select the monitor that you want to disconnect under the “select and rearrange displays” section. After that, select “disconnect this display option” under the “Multiple Menus” section.
