RE: True color failed to apply the requested settings - Dell Inspiron 5547
go to programs and features in windows 10, there you will find true color application right click and tap change, this will repair or reinstall the application.Even i have upgraded to windows 10, true color works fine with me, yes sometimes it doesnt respond, only somtimes. In windows update you will get update for intel graphics it will be
Intel Corporation - Graphics Adapter WDDM1.1, Graphics Adapter WDDM1.2, Graphics Adapter WDDM1.3, Graphics Adapter WDDM2.0 - Intel(R) HD Graphics Family
just update these things also, i remember seeing somewhere in internet that intel might be the culprit for this problem.
after repairing true color 99% chances are that it will work.otherwise uninstall True Color and redownload it from here
Last thing i have to say is dell people are working on this issue itseems as they told to my friend who had the same problem when he called. wait patiently until they release the fix.
