Click on Start, then type "dccw.exe" in the search engine line. When "dccw.exe" shows up in the upper left display, RIGHT click on the file name, choose "Run as administrator". This should open the basic "Calibrate Color" work screen in admin mode and should allow your settings to "stick" once you've changed them. At least, I hope so.
Hope this helps.
I have a Dell XPS 15 (L502X) laptop with
Intel Core i7-2630QM processor
6 GB DDR3 RAM
15.6" Full HD LED Screen
2 GB NVIDIA GeForce GT540M with Optimus
My display was a little 'warm'. I mean that what should appear as white didn't appear white, instead it appeared creamy (i.e. according to RGB scheme, the red content in the display was more than what is required.)
To fix this, I did this
Right Click Desktop > Personalize > Display > Calibrate Color and then adjusted the red and green bars to make the color settings proper. Now, the display is as I want it to be.
The problem is that when the PC reboots or when an UAC window pops up, the settings are lost and again my display becomes 'warm'/creamy.
I've tried going to Control Panel > Color Management and doing what this says: www.pusztaiphoto.com/articles/colormgmt/win7/
Some thread told me to uncheck igfxpers.exe in msconfig > startup but I can't find it.
Any help would be greatly appreciated.
