Some type of blue colors turn purple on my monitor.

Hi Yahya. I'm Greg, 10 years awarded Windows MVP, here to help you.

1) Try these fixes for blues rendering purpose on monitor:

2) The Display driver is so important here that merely updating it is sometimes not enough. So let's try everything possible to get it working correctly:

First make sure you have updated the Display driver from the PC or Display adapter maker's Support Downloads web page for your exact model number, HP Serial Number or Dell Service Tag - from the sticker on the PC.

While there check also for newer chipset, BIOS/UEFI firmware (very important), network, sound, USB3 and other drivers, comparing to the ones presently installed in Device Manager reached by right clicking the Start Menu.

Remove the old driver using DDU https://www.wagnardsoft.com/content/ddu-guide-t... if necessary installing in Safe Mode with Networking (so you have internet), or Safe Mode, accessed by one of these methods: https://winaero.com/how-to-boot-windows-11-in-s...

If this doesn't give you the latest or ideal driver for what you need, compare it to the driver offered by the Intel driver update Utility here: https://www.intel.com/content/www/us/en/support...

or the Nvidia GeForce scanner here: http://www.nvidia.com/Download/Scan.aspx?lang=e...

or the AMD autodect utility here: http://support.amd.com/us/gpudownload/windows/P...

For Display issues one fix that is working is to Roll back or Uninstall the Driver on the Display Device > Driver tab, restart PC to reinstall driver. You can also try older drivers in Device Manager > Display device > Driver tab > Update Driver > Browse > Let Me Pick.

Then you will know you've tried everything in addition to Windows Update drivers.

Adjust the screen resolution until it fits and looks best at Settings > System > Display.

Then expedite all WIndows Updates including Optional to see if it pushes Monitor or other enabling drivers.

Check for a monitor driver by expediting Windows Updates (including Optional Updates) in Settings > Update & Security > Windows Update > Check for Updates to install all Updates until no more are offered.

Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.

Anything to do with drivers did not help.

I recently downgraded to windows 10 and now it's better.

Something to do with either the drivers or Windows 11 being full of glitches

I have the same problem.

I am currently running windows 11 21H2. I had experienced this once but somehow I fixed.

This didn't come back again until the 22H2 update comes out recently. I have try updated and rolled back twice. Once I updated to 22H2 built, all blue in my explorer and apps became purple.

The Dell "color profile" is bugged on some Dell monitors, mine included. Start > Color Management and under the first 'Devices' tab. Remove the dell color profile and restart if need be, should hopefully fix it.

This fixed issues for me. Thank you!
