Display's color calibration settings are lost on reboot

by arpitchauhan / August 16, 2011 4:10 AM PDT

I have a Dell XPS 15 (L502X) laptop with

Intel Core i7-2630QM processor
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:

Some thread told me to uncheck igfxpers.exe in msconfig > startup but I can't find it.

Any help would be greatly appreciated.

Tried "Run as Administrator"?
by Grif Thomas Forum moderator / August 16, 2011 5:02 AM PDT

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.

Thank you for thesuggestion; did not work on my machine

Thank you for mentioning dccw.exe, and running as administrator.
Followed your suggestion, but after waking from sleep the adjustment is again lost.
This is annoying to say the least, as I'm using the laptop to show photos to friends, and the manufacturer (HP) have set the screen to a rather bluish tint.
Any suggestions on how to make Windows 7 Starter remember how I prefer my colours greatly appreciated.

Windows 7 Starter

It seems this edition of Windows has limitations;

Windows 7 Starter does not include:

* Aero Glass, meaning you can only use the Windows Basic or other opaque themes. It also means you do not get Taskbar Previews or Aero Peek.
* Personalization features for changing desktop backgrounds, window colors, or sound schemes.
* The ability to switch between users without having to log off.
* 64 bit version
* Multi-monitor support.
* DVD playback.
* Windows Media Center for watching recorded TV or other media.
* Remote Media Streaming for streaming your music, videos, and recorded TV from your home computer.
* Domain support for business customers.
* XP Mode for those that want the ability to run older Windows XP programs on Windows 7.

Note that Personalization features like changing Windows Colors is not included.

There is more about that in the link below;

Thank you, calibrate display works but does not stick

In reply to: Windows 7 Starter

Dear Mark,
Thank you for the prompt reply.
Control Panel > Colour Management > Advanced > Display Calibration allows me to adjust the screen tint using Red, Green and Blue sliders.
Once I have clicked 'Finish' the screen actually has a less bluish tint.
So it works, but only until the machine goes to sleep, or I shut down and reboot.
The X-rite i1 Display Pro calibrator also allows to calculate and save a colour profile.
Setting this profile as default does not result in the correct calibrated tint at boot-up - unless I go to Colour Management and set the profile as default.
Hence the use of the Display Calibration sliders.
Any further suggestions appreciated.

Yes that's right

I would say that is what the limitation is. It seems you can make changes, but on reboot the changes revert back to default settings.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
