Windows 10: Color Calibration and gamma settings keep resetting !!!

I have to continuously run color calibration because I notice my email and other web pages are being washed out in white......I lower the gamma settings as low as they will go and it gets better, but then resets from sleep or after reboot or just randomly.


I tried saving the profile in ICC as default and it shows there still, but gamma continues to change on its own.


Intel does not have a section to correct this.


Uninstalled both Nvidia and INtel drivers and reinstalled in compatibility mode but hasn't changed anything.


Not using the NVidia , have uninstalled and reinstalled just in case.

Gamma always too high during Windows 10 color calibration

I'm using a TV monitor (an old memorex MLT1931, 19", if it matters) as a second monitor. I am using it with the same resolution as my other monitor (1920x1080), and its native resolution is 1280x720. Some of the colors are off, and my radeon advanced settings didn't seem to do much, and now I'm just doing the normal Windows 10 color calibration.

The issue I'm running into is that during the "adjust gamma" step, no matter how high or low the slider is, the image to the right of the slider always look like the "gamma too high" example, with a darker dot in the middle (like in this photo). The rest of the screen gets brighter/darker, but the dots stay the same.

When I switch the calibration window to my good monitor, the gamma is fine and I can see the dots adjust from bright to dark as I move the slider.

Any ideas why?

 

Windows color calibration tool and resetting calibration


I went and ran the built in color calibration tool in Windows 10 to adjust gamma, brightness, contrast etc but I want to restore this back to what it was before I ran this calibration tool. How do I do that? There does not seem to be an obvious "Restore Default" button anywhere.

Do I simply delete / remove the Profile listed in the box under Start-Settings-Colour Management and maybe untick the box "Use my settings for this device"?

Thanks.

 

If you mess with Calibrate display color. settings... can you reset it?

Giving this a bump since i seemed to get just generic answers that didn't even read the question:

Anyone have an answer? Its a pretty simple question. Once you change the gamma slider in the windows calibrate display color/display color calibration settings, if you later change your mind and go back can you reset it to the default or not? Or will the
new 'reset' be whatever you had changed it to?
