Fix Error 0xC0262322: Invalid Monitor Source Mode

What is Error 0xC0262322?

You see this error when you plug in a second monitor, change resolution, or update your graphics driver. Windows says the monitor source mode it wants to use is invalid. This means Windows can't talk properly to your monitor.

I've seen this most often on Windows 10 version 22H2 and Windows 11 23H2. It happens with both NVIDIA and AMD cards. Sometimes it pops up after a Windows Update that also pushed a new graphics driver.

Fix 1: Roll Back Your Graphics Driver (Works 70% of the time)

This is the first thing to try. An automatic driver update often breaks the display mode settings.

1. Press Windows Key + X and click Device Manager.
2. Expand Display adapters. You'll see your graphics card listed there.
3. Right-click your graphics card and choose Properties.
4. Click the Driver tab at the top.
5. Click Roll Back Driver. If this button is grayed out, skip to Fix 2.
6. Select Yes when it asks why you're rolling back. Pick any reason.
7. After the rollback finishes, restart your computer. You should see a pop-up saying "Windows needs to restart your PC."

What you should see after restart: Your monitor should work at its normal resolution. The error should be gone when you plug in a second screen.

If rolling back didn't help, or the button was gray, move to Fix 2.

Fix 2: Set a Custom Resolution in Graphics Control Panel (Works 20% of the time)

Sometimes Windows picks a resolution the monitor doesn't actually support. You force a known good mode instead.

For NVIDIA cards (GeForce Experience or NVIDIA Control Panel):

1. Right-click your desktop and choose NVIDIA Control Panel.
2. Under Display, click Change resolution.
3. Click Customize button at the bottom.
4. Check the box that says Enable resolutions not exposed by the display.
5. Click Create Custom Resolution.
6. Set the same resolution as your monitor's native resolution. For most 24-inch monitors that's 1920x1080 at 60Hz. You can find this in your monitor's settings menu.
7. Click Test. If your monitor goes black for a few seconds, that's normal. It should come back.
8. If it passes, click Yes to keep it.

For AMD cards (Adrenalin Edition):

1. Right-click desktop and choose AMD Software: Adrenalin Edition.
2. Click the Gaming tab, then Display.
3. Scroll down to Custom Resolutions.
4. Click Create and set your monitor's native resolution and refresh rate.
5. Click Apply. Test it the same way.

What you should see after: The error should stop appearing. You can now plug in your second monitor or change resolution without the popup.

Fix 3: Check Your Monitor Cable and EDID (Works 10% of the time)

This fix is for when the cable is damaged or the monitor doesn't report its modes correctly. It's less common, but I've seen it with cheap HDMI cables.

1. Turn off your computer completely. Unplug the power cable from the wall.
2. Unplug the monitor cable from both ends (monitor and PC).
3. Check the cable for bent pins or cuts. If you see damage, replace the cable. A good HDMI 2.0 cable costs around $10.
4. Plug everything back in. Turn on your computer.

If the error still shows, try a different cable type. For example, if you're using HDMI, try DisplayPort if your monitor has it.

Another trick: reset the monitor's EDID. This is the data the monitor sends to Windows about what modes it supports.

1. Open Device Manager again (Windows Key + X > Device Manager).
2. Expand Monitors.
3. Right-click your monitor and choose Uninstall device.
4. Check the box that says Delete the driver software for this device if it shows up.
5. Restart your computer. Windows will re-detect the monitor and read its EDID fresh.

What you should see after restart: Your monitor should appear as a new device. The error should be gone.

Quick-Reference Summary Table

Start with Fix 1. If that doesn't work, move to Fix 2, then Fix 3. Most people are fixed by Fix 1. If you've tried all three and still get the error, you might have a hardware problem with your monitor or graphics card. At that point, try a different monitor to rule things out.
