Do not apply any changes for assigned profiles here. A Color Management setup window for the System Level appears.
If the option "Use Windows Display Calibration" is grayed out, click on "Change System Defaults" bottom left in the window. Click on the "Advanced" tab and check the box to "Use Windows Display Calibration" to control loading the video LUTs.
Make sure that the X-Rite created monitor profile is selected as the default.
In the "Devices" tab, add a check to "Use My Settings for this Device". Open Control Panel and then "Color Management". Dell monitor menus tend to place “DDC/CI” in the “Other Settings” of the menu. If so, disable it or turn it off in the display’s menu. Reset the display to factory settings and then check to see if the display’s menu has “DDC” or “DDC/CI” enabled or turned on. Scroll down to select "Windows 7 Basic" theme instead of a "Windows Aero" theme. Go to Control Panel and then open "Personalization". Turn off the system’s semi-transparency "Aero" desktop theme. Note: it might be necessary to reinstall the X-Rite profiling software with UAC set to never notify. Drag the slider down to "Never Notify" and click "OK".
Open Control Panel > "User Accounts" and select "Change User Account Control Settings". Uncheck the option to "Use This Program". Open Control Panel "Windows Defender", select "Tools" > "Options" > "Administrator".
Be sure to be using the most current version of the X-Rite profiling application. Some users have reported that their X-Rite created display profile looks great but it will be “unassigned” or “kicked out” after a period of time…after the PC goes to hibernate or standby, after restarting the PC, or simply after a certain period of time! If a user is sure that their display profile is being un-assigned by the Windows 7 operating system, consider the following recommendations first. Although this was written for Windows 7, everything will apply except for Aero Mode…Windows 8 and Windows 10 have dropped that visual theme.
