Photoshop Causes Monitor to Brighten Significantly, Adds Blue Shift

I've had a strange thing happen with the most recent version of Photoshop the last few days.

As soon as I click on the icon to start PS, the entire monitor screen brightens significantly. It also shifts significantly to the blue, cooling the photos. Once I exit PS, my monitor brightness returns to zero.

I should stress, this increase in the brightness and cooling affects all problems, not just PS, for as long as PS remains running.

I use a calibrated monitor. This strange PS behavior means I can't edit while PS is running. The results are too bright and too blue.

I'm running Windows 10 with 16GB of RAM and an SSD as primary drive and mechanical hard drive as the secondary drive.

Cheers,

Mitch

I use a calibrated monitor.

By @glennm33209809

Calibrated how and with what calibrator?

Does this affect the entire interface, or is it limited to image/histogram/color picker? If the former, it's a bad video driver, if the latter, a bad monitor profile.

Do you have screenshots that could illustrate? (don't attach, insert image directly into the post).

I have my ICC monitor profile set to use a D65 white point and illuminant of 160 cd/m3. Standard tone response curve. Gamma 2.2. I use i1Profiler from Xrite to calibrate my monitor.

From your description, it sounds like the calibration tables are thrown out from the video card. This is stored inside the profile for convenience, but is actually not part of the profile as such (which is a standard icc profile).

As for why this happens when Photoshop is open, that's a mystery and something I have never heard about before.

But there is still a pattern of some kind here. The recent 22.3 update seems to be problematic in several ways, and most of the reported problems seem associated with the GPU/video card/driver. So that could be a link.

In short: Try to revert to 22.2, and see if this particular problem goes away. If it does, it should be reported as a bona fide bug on the feedback site. To revert, open the CC desktop app, uninstall PS and reinstall.

When you reinstall, click the three dots to get "other versions", and pick 22.2. (I had to do that because of a different bug in 22.3).
