Changing the monitor identity number in Windows 11 isn’t exactly rocket science, but it can be a little confusing if you’re new to multi-monitor setups. Basically, it’s about organizing how Windows recognizes your screens—so when you move your mouse or drag windows around, everything lines up the way it should. It’s handy if you want to set a specific monitor as primary, or just want the numbers to match your actual desk arrangement. Doing it right means a smoother workflow and less annoyance trying to figure out which screen is which.
How to Change Monitor Identity Number in Windows 11
Open Display Settings and Get a grip on your monitors
First off, right-click anywhere on your desktop and pick Display settings. Yeah, it’s that simple. This opens up the big window where all the monitor magic happens. From here, you’ll see icons representing each display. If things look weird or screens are blank, check your connections first—sometimes Windows just refuses to recognize a monitor if it’s unplugged or turned off.
On some setups, the display icons might not match your physical setup right away. No worries. You can use the next steps to make sense of it all.
Identify your monitors – the big numbered reveal
Click the Identify button—usually found below the display icons. Big numbers pop up on each screen, telling you what’s currently what. So if monitor 1 shows a big “1, ” and you see that on your left screen, but you wanna move things around, this helps you figure out which is which. Sometimes, the numbers look off or are duplicated, thanks to Windows being a little funny about recognizing multiple displays.
Pro tip: on some PCs, clicking identify might flicker or not work the first time. Just re-click or restart display settings if needed. The goal is to see which monitor is which, and then get ready to rearrange.
Rearrange the monitors — aligning virtual with real life
Drag those monitor icons to match how your physical screens are laid out. For example, if you have a monitor on the right side physically, make sure it’s on the right in the settings. This is pretty crucial because Windows uses this layout to move your mouse smoothly from one screen to another. Misaligned icons = mouse jumping around randomly. Not fun.
If you have more than two screens, it’s worth physically labeling them with sticky notes or tape to avoid confusion. On some setups, the monitor number doesn’t change automatically with this, but it’s a step closer to a proper setup.
Apply and confirm your changes
Once you’ve moved everything to match your setup, scroll down (if needed) and hit that Apply button. Wait a couple of seconds—think of it as Windows catching up with your brain. A dialog will pop up asking if you’re happy, and you should click Keep changes if all looks good. If something looks off, just revert or readjust and do over.
Sometimes, after applying, you may notice the monitor numbers don’t update instantly or seem inconsistent. That’s normal; a quick restart of Windows sometimes helps tidy things up, but usually just toggling the identify button again does the trick.
Check if everything is sorted
Finally, make sure the monitor numbers match what you expect. If your primary screen shows as 1 and that’s correct, then the setup’s good. You can also select a monitor and mark it as Make this my main display for easier taskbar access and desktop icons. Sometimes, Windows doesn’t assign primary correctly, and fixing that can solve a lot of annoyance down the line.
It’s a bit of trial and error, especially with complex setups or if your hardware is quirky, but once it clicks, everything feels a lot more natural.
Tips for Changing Monitor Identity Number in Windows 11
- Double-check all cables before you start — Windows can’t recognize what’s not connected properly.
- If the ‘Identify’ button doesn’t work right away, try restarting display settings or Windows itself.
- In case Windows gets confused, disabling and re-enabling displays or updating graphics drivers (via Windows Update) might help.
- Physically label your monitors if you have multiple—this makes matching the software numbers to real monitors way easier.

Frequently Asked Questions
Why bother changing the monitor identity number?
It just makes your workspace way less confusing. When you know which monitor is which, drag-and-drop and window placement get way more predictable. No more accidental drag to the wrong screen.
What if Windows doesn’t detect my monitors properly?
Make sure all cables are tight and correct. If that doesn’t work, a quick restart or updating your graphics drivers through your GPU manufacturer’s site can often fix recognition hiccups.
Can I designate any monitor as primary?
Totally. Just click the monitor you want, then check the box that says Make this my main display. This is super useful if you want to ensure your taskbar lands on the right monitor.
Do I need any special software?
Not really. Windows 11 provides everything needed for basic monitor identification and arrangement. Sometimes graphics driver tools can give more options, but for most folks, the built-in controls do the trick.
What if the ‘Apply’ button just stops working?
This is weird but can happen. Usually, it’s linked to outdated drivers or Windows bugs. Updating graphics drivers or running Windows Update might fix the glitch. Sometimes, a quick logoff/logon cycle helps too.
