Investing in quality monitors designed for gamers like the best 27-inch monitor for gaming for a multi-monitor setup will also significantly improve how you experience video games.

Fixing the 3rd Monitor Not Detected in Windows 10

Here are steps you can take to fix the third monitor not detected in Windows 10. The steps are similar to when your computer won’t detect a second monitor, especially when you’re trying to set up dual monitor wallpaper in Win 10. Expect to take no more than 10 minutes with this task.

Step 1: Check All Connections

Unplug all monitors and plug them back in. Check out this guide to monitor port types if you need to troubleshoot specific ones or would like to learn more about all types. Try three attempts to let auto-detection find and display the third monitor on the screen before proceeding to the next troubleshooting step. Additionally, perform a thorough check of all of your cables to make sure there is no exposed wiring that could result in a short circuit. Your cables might have gotten loose if you’ve got a big setup of the top flat monitors and best curved monitors.

Step 2: Change Your Control Panel Display Settings

If your third monitor continues to not display, press the Start button and access the Control Panel or right-click on your desktop and hit Display > ‘Change Display Settings.’ From the Change Display Settings screen under the ‘Multiple Displays’ section dropdown menu, click on ‘Extend These Displays.’

Wait for a few seconds and see if your third monitor becomes recognized. If it is not recognized, then proceed to Step 3. We should note that you can avoid these triple monitor issues if you want to consider a dual setup if you know the differences between two monitors vs three.

Step 3: Check Windows Updates Compatibility and Graphics Card Drivers

If your Control Panel Display Settings fails to detect the third monitor, it could be due to a lack of updates. Install the latest Windows 10 updates by clicking on ‘Settings’ and clicking ‘Check For Updates.’ This will automatically download all of the latest updates to your computer, which could address the compatibility issue. The Microsoft Update Catalog website is an excellent place to check for the latest updates, some of which may be bug fixes related to displays and overall connectivity.

In some minor cases, graphic cards could prevent third monitors from being read. Be sure to check for the GeForce driver updates by visiting NVIDIA’s official website to get the latest update to your graphics cards. If your monitor uses competitor AMD’s FreeSync, it also follows a similar process.

In most cases, Step 2 will be the end-all, be-all for fixing the third monitor not detected in Windows 10.

If all else fails, another trick is to restart your computer before completing Step 2. Sometimes, background processes may interfere with the connection between your monitor and computer which may trigger issues like when a monitor says no signal.

More importantly, if you can’t get the third one to work at all, you may want to ask yourself if perhaps an ultrawide monitor is worth it? You’ll save yourself a headache with one monitor instead of three. If your eyes constantly bother you while you’re using your monitors, consider the best monitors for eyes as well.

STAT:

Setting up two monitors can improve your productivity. Recent studies show that using multiple monitors cuts down on toggling from window to window. Over the course of an 8-hour workday, that can save you 15 whole minutes of toggle time – https://www.pbergo.com/just-how-many-monitors-do-you-need/
