Long story short, whenever I use a feature that is heavy on the video card, I get a hideous yellowish/greenish tint over everything.
By heavy on the video card, I mean, if I open up a game and I can see it once it starts to load 3d models and such change the colors.
I’m able to get back by going into dispcalgui, resetting the video card gamma table, and then reinstalling the profile. Interestingly, reinstalling the profile without resetting the gamma table doesn’t change it.
Has anyone else had this problem? I’m not finding much direct information related to it.
Windows Color Calibration in color management is OFF
I have a Nvidia GTX 660, latest drivers
Latest version of argyll and dispcalgui
Spyder5 (don’t know if that makes a difference)
Windows 72015-07-23 at 22:58 #807Yes, some applications (including games) will unfortunately reset the video LUTs whenever they’re used, thus unloading the calibration. You can use the dispcalGUI Calibration Loader to restore the calibration after exiting the game.

Oh my, that’s ridiculous. Why on Earth… Is there any workaround or anything like that?
Professional applications like Maya or photoshop don’t do this, right? I just loaded up Maya but I don’t know if I can totally trust my eyes right now, it might be subjective…
By the way, thank you for your prompt response, feeling a little less lost.

No, they honor calibration and in the case of Photoshop also actually use ICC profiles. But fullscreen 3D apps like games or benchmarking tools can be problematic.
2015-07-23 at 23:44 #810Makes me want to go visit various game devs and give them a slap on the wrist. What are they thinking? Have they never heard of leaving well enough alone?
Anyway, don’t mean to rant gratuitously but I use this computer for making art and playing games, do you know of any, hopefully painless, workarounds?
2015-07-23 at 23:46 #811I’ve heard about a tool that enforces the calibration to stay loaded but I can’t remember the name.
2015-07-24 at 0:11 #812I also just noticed that when I’m looking at videos posted on facebook where the first frame of the video is visible before playing, the colors shift when I click play again.
Geez, I don’t know, this is starting to look very untenable, is there some way to color correct without altering the LUT table from its default? I’m surprised to see that we’re still having problems like this in 2015…
2015-07-24 at 0:16 #813I also just noticed that when I’m looking at videos posted on facebook where the first frame of the video is visible before playing, the colors shift when I click play again.
The first frame is likeliy just an image which in some browsers (depending on if they support ICC color management and how it’s configured in the browser) is color managed, but when you start playback Flash takes over (which is not color managed afaik).

The issue with video you’re seeing is not related to the graphics card videoLUT (gamma table), it’s just that video in browsers is generally not color managed.
2015-07-24 at 0:23 #814Is there a way in dispcalgui, at least for experimentation, to calibrate the display without altering the LUT?
From my perspective, it seems like it’s worth a try, at least.
2015-07-24 at 0:25 #815No. The only thing you can do is adjust the whitepoint.
2015-07-24 at 0:36 #816Fair enough, I dug around and if anyone else is having this problem, I found these two free applications for forcing LUT use.
Thank you for all of your help Florian Hoech.

Just one more question, I am using a Spyder5 and I find when I’m calibrating, that the black patches seem to take a long time, is there anything I can do to make them less error-prone?

It’s normal for dark patches taking longer to measure, this is not an error. The Spyder instruments are unfortunately not very sensitive and thus slower than competing products.
In other news, recently I learned that 3D LUTs can be used with the MasterEffect ReBorn shader library for ReShade, thus enabling color management for games. Support for creating compatible 3D LUTs will be in the next version of dispcalGUI.
