Calibrating multiple monitors can be a real pain, especially if they aren’t the same models. To make matters worse, Photoshop might be altering your image colors on the fly with the help of your GPU.

This problem is most noticeable when you drag your Photoshop window between 2 monitors. After a moment of waiting or if you adjust the image in any way, the colors will suddenly shift. They might suddenly appear washed out or supersaturated. The problem itself is always there, you just might not notice until it suddenly shifts.

This effect does not occur when viewing images outside of Photoshop, such as in a web browser or your pictures folder.

It is especially nerve-wracking when you are trying to figure out whats wrong. Is it your monitor settings? Did you do something wrong in Photoshop color management? Is it your graphics card control panel or maybe a rogue HDMI/DVI connection? Actually it is none of the above.

Actual Example of the Issue

The following image was screen captured from Photoshop CS4 while dragging an image between 2 Samsung panels.

Photoshop Color Changing Solution

This problem has been discovered and discussed by quite a few people. In some search results, there are hints that it is caused by OpenGL Drawing on certain graphics cards.

This is close, but not quite the answer. What you need to do to keep consistent images is turn off “Color Matching,” which is a checkbox under the same GPU settings section as OpenGL.

This should take care of the frustrating color changes that occur when moving images between monitors. If you have any questions or if this tip helped save your sanity, leave a comment!
