Try updating your projector firmware and checking if the projector's HDR mode is enabled. For Kodi, manually set the resolution instead of using Auto. If issues persist, test with a different media player to see if the problem is specific to Kodi.

Try updating your SSD firmware from WD’s official site. Also, check if there are any BIOS updates for your board. If issues persist, consider testing the remaining drives on a different system to isolate the problem.
