How do I extend the desktop to three monitors in Windows 11?

Anonymous

I have a three-monitor setup: one monitor is built into my laptop, one is connected via the laptop's HDMI port, and the third is connected via a USB to HDMI extender. All 3 monitors are recognized when I go into display setting, and I can see my desktop on all three monitors. Further, I can extend my desktop to monitors 1 and 2 or to 2 and 3 but not to all three at the same time. This worked seamlessly in Windows 10, but I'm having issues in Windows 11. I'm in the process of migrating to a new laptop. The laptop's bios is up to date, and it was necessary to install a new driver for the USB to HDMI video extender (a J5 Create model JUA365) to get the 3rd monitor to show up in the Windows 11 display settings.

The problem I'm seeing is that there is no option such as "Extend the desktop to all monitors" in the display settings. I've seen all of the following choices: "Extend desktop to 1 and 2," Extend desktop to 1 and 3," "Extend desktop to this display," "Disconnect this display," "Duplicate desktop on 1 and 3, and "Duplicate desktop on 2 and 3." All of the choices listed here seem to work except "Extend desktop to this display." Based on these choices, I'm expecting to extend the desktop to 1 and 2 (which works), then select monitor 3 among the available monitors that appear in the monitor configurator, then select "Extend desktop to this display." But that isn't working. As mentioned, the first part works. The second part seems like it's going to work in that the displayed content on all the monitors momentarily shrinks, then snaps back to full size. However, I still can't access the third monitor with my mouse.

Answer 1

Thank you so much! I have been working with 1 external screen for 3 weeks now and wasted hours changing drivers etc.

This step solved my issue immediately. So simple but so hard to find the solution online.

The steps that most likely fixed the problem involved using the display configurator found at settings => system => display. Specifically, from within the configurator, I selected monitor 3 then chose "Disconnect this display" from the dropdown menu available in the interface. With monitor 3 still selected, I then chose "Extend desktop to this display" in the same dropdown menu. After that, everything worked.

I figured out the answer to my own question. First I moved the HDMI output cable coming from my monitor 3 (the monitor I was having issues with) from the HDMI 4K port to the standard HDMI port on my external USB to HDMI converter. This alone did not fix the problem, and I'm not sure the step is even necessary. Just mentioning it in case.

During the above process, some confusion arose while I was getting the monitors arranged properly in the configurator to match my physical setup. Here the trick was remembering to click on "Apply" after adjusting the virtual monitor arrangement before testing whether Windows "understood" my physical setup. Because of this, it's possible that the only problem I was facing the entire time was failing to click "Apply" before testing the setup. In any case, if you're having a similar problem to mine, try all of the above.

Finally, I get why the monitor configurator dropdown choices are the way they are, but an additional "Extend desktop to all monitors" option would seem to also make sense.
