Windows 10: Cannot extend display to second monitor

I am using windows 10 pro on my Powerspec desktop PC. I have one HP monitor and one AOC monitor. I had three monitors (one HP and 2 AOC monitors) working fine using extended display. After removing one monitor (now have 2), the extended display does not work any more. I can use "Duplicate these displays", "Show only on 1" or "Show only on 2", all work fine, except "Extend these displays". When I select Extended, the second screen shows up with task bar, but I cannot move any window onto the second screen. The mouse does not move over either. I tried update the display driver, rebooting computer, reconnect the cable, nothing works! What's wrong?

Duplicating taskbar across multiple displays.

Hello,

In setting up two display monitors, options like Duplicate these displays, Extend these displays, Show only on 1, and Show only on 2 are provided to customize the display settings. In choosing Extend these displays, which lets you extend your actual working
area to the second monitor, a primary or main monitor is set up as well. The primary monitor is generally the one that displays the majority of details and hosts the primary desktop. Although the Taskbar is available on both the monitors, but the primary one
is more functional and accessible. The icons you see in the main monitor cannot be displayed on the second monitor as well, this is the distinction between the main display monitor and the extended or second monitor, which is a software design.

Feel free to post your query should you need assistance.

 

Second monitor shows same screen as first, but not detected

My second monitor was working fine (extended), then after a restart it came on with the identical display as the first. I went to display settings and a second monitor cannot be detected even though it is showing. I looked at the control panel drivers and
there is no update. Any ideas?

Try moving the mouse cursor in the opposite direction. If that tracks to your other screen, you can rearrange your monitors in the Display Settings area and get things working properly.

Thanks a lot Ed! You are right, when I move mouse to the opposite direction, it went to the other screen! I guess the order of the screen is wrong. How do I rearrange the order? Thanks again for your quick help!

 

I was able to drag my screen and change the order on Display Settings. Now it work correctly. Thanks, Ed, for your help! Save me hours of frustration!

 

Glad to be of service Wendy Lou! You figured it out before I saw the post had been answered. Good for you. Glad it worked.
