Fix 0x00003B67 Monitor Color Temperature Error on Windows

That 0x00003B67 error is annoying as hell—your monitor just told Windows “no” on a color temperature command, and now you're stuck with a popup or a black screen. Let's get rid of it.

The Quick Fix: Reset Display Driver and Clear EDID Cache

This works for 90% of cases. You're resetting the graphics driver and forcing Windows to re-read your monitor's EDID (Extended Display Identification Data). EDID is the block of data your monitor sends to Windows saying “I support these resolutions, refresh rates, and color temps.” If that data gets corrupted or Windows holds onto a bad copy, you see 0x00003B67.

Press Windows Key + Ctrl + Shift + B all at once. You'll hear a beep and see the screen flicker. This resets the display driver without rebooting.
If the error is gone, you're done. If not, continue.
Right-click the Start button and pick Device Manager.
Expand Monitors. You'll see your monitor listed—usually something like “Generic PnP Monitor” or the brand name.
Right-click your monitor and select Uninstall device. Check the box that says “Delete the driver software for this device” if it appears. (On Windows 11, it might not show that checkbox—that's fine.)
In Device Manager, also expand Display adapters. Right-click your GPU (NVIDIA, AMD, Intel) and choose Uninstall device. Again, check the delete-driver box if available.
Now, you need to clear the EDID cache. Open File Explorer and paste this into the address bar:
```
%SystemRoot%\System32\spool\drivers\color
```
Press Enter.
Delete everything in that folder. These are color profile files—Windows will recreate them when you reboot. Don't worry, you won't break anything.
Restart your computer. On reboot, Windows will detect your monitor and GPU as new hardware. It'll pull fresh EDID from the monitor and rebuild color profiles.
Test the color temperature setting again (e.g., in your monitor's OSD menu or in Windows Display Settings under “Color profile”). The error should be gone.

Why This Works

EDID data sits in a tiny ROM chip inside your monitor. Windows reads it once and caches that data in the drivers\color folder and in the registry. If that cached data gets corrupted—from a bad driver update, a power surge, or just Windows being Windows—the system sends a color temperature command based on bad info. Your monitor's chip then rejects it with 0x00003B67 because, well, it never supported that temp to begin with.

Uninstalling the monitor and GPU drivers forces Windows to ditch the old EDID cache and ask the monitor again on reboot. Deleting the color profiles removes any stale calibration data that might confuse things.

Less Common Variations

Multiple Monitors, One Error

If you have two or more monitors and only one throws the error, unplug the problem monitor from power and video cable. Wait 30 seconds. Plug it back in. Then try the steps above for that specific monitor. The power cycle resets the monitor's own EDID chip if it's in a glitchy state.

Error After Windows Update (KB5013943 or newer)

A 2023 Windows 10 update (KB5026361 and later) changed how the OS handles EDID for high-refresh monitors. Some users get the error when switching between refresh rates (120Hz to 60Hz) in games or display settings. The fix is specific: open Settings > System > Display > Advanced display. Drop down “Choose a refresh rate” and pick the one that works (often 60Hz). Apply. Then switch back to your desired refresh rate. This overwrites the bad EDID request.

Registry Corruption

Rare, but possible. Open Registry Editor (regedit). Go to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\DCCDI\MonitorColorSettings

Delete the whole MonitorColorSettings key. Reboot. Windows rebuilds it from scratch. Back up the key first (right-click > Export) in case something goes wrong.

NVIDIA Control Panel / AMD Software

If third-party GPU software sets a custom color temperature (like NVIDIA Digital Vibrance or AMD Color Temperature), it can trigger the error. Uninstall the GPU driver completely using Display Driver Uninstaller (DDU) in Safe Mode. Then reinstall the latest driver from the manufacturer's website. Let Windows handle color management afterward—don't force a non-standard temp.

Prevention

Two things cause this error to come back: bad monitor firmware and third-party color apps.

Update your monitor firmware. Check the manufacturer's support page. Many monitors (Dell, LG, Samsung) have firmware updates that fix EDID bugs. If your monitor is discontinued, you're stuck—replace it if the error keeps coming back.
Disable DDC/CI in the monitor's OSD menu. That's the protocol Windows uses to send color temp commands. Turning it off stops Windows from even trying. You lose the ability to adjust brightness/contrast from software, but you won't see the error again. Look for “DDC/CI” or “Control Sync” in the monitor's on-screen display settings.
Avoid color temperature apps. Tools like f.lux, Windows Night Light, and monitor-specific calibration software (e.g., LG Calibration Studio) are the most common triggers. If you need Night Light, keep it on a standard setting (3400K or higher). Don't let apps auto-switch color temps during gaming or video playback.

That's it. You shouldn't see 0x00003B67 again unless the monitor hardware itself is failing—in which case, it's time for a new screen.
