Uninstall DDM 1.56.0.2107. Install DDM 2.0.0.134 and retest.
Hi All, Can anyone help me please?  I've been trying to fix this for a while. Dell 27" S2721DGFWindows 11 Home N 21H2DDM (Dell Display Manager) 1.56.0.2107.When I enable HDR from Windows, DDM has both Manual Mode and Auto Mode greyed out and can't change any of the options in it. [IMAGE] If I disable HDR from Windows settings, all the options are back. [IMAGE] Any solutions? Best regards.
