Are you working with 2 screens connected? Mac or Windows? I am guessing Mac.
I have seen an issue on Mac which sounds rather like this - with dual screens (mirrored) and Photoshop, but not just Photoshop.
In my case, opening another application will make Photoshop's display change as if it's dropped the display profile, I am convinced that it's something to do with the monitor profile implementation and OSX.
In my case, it helped a lot to first quit Photoshop then go to Mac system preferences / displays / arrange and set the menubar onto the screen that I consider the main one [master screen]. That’s the one that has my main Photoshop editing window.
Once you've done that, Photoshop should open on that [master] screen. Go to Photoshop - edit/ color settings and under working spaces / RGB if you click there you'll see, with in the pulldown that opens, the "monitor RGB" should be showing the icc profile for that main monitor.
Doing that has fixed my own issues.
[BTW do not select the Monitor RGB there in color settings by highlighting it, we don't wish to use it as our working space. Just to be sure you left all as it should be why not cancel rather than OK to exit?]
ps, changing settings on the screen is not god, ideally you need to have a calibration and profiling method, I mean a sensor and good software to keep the system calibrated and consistent. There is some info about that here: display screen colour management, calibration and profiling | colourmanagement.net
I hope this helps you, if not please come back with more detail
if so, please do mark my reply as "helpful" and if you're OK now, please mark it as "correct answer" so others who have similar issues can see the solution

This is consistent with using a wide gamut monitor, and viewing with and without proper color management.
Save For Web at default settings displays without color management. To enable it, you need to check "embed color profile", and set preview to "use document profile".
Photoshop (main app) always displays with full color management. If the file doesn't have an embedded icc profile, the working RGB is assigned.
So. When you say you "checked your color settings", what exactly do you mean by that? Screenshots of Color Settings and the SFW window would help.
And what monitor(s) are you using?
By fiddling with the color settings on my SFW window as you explained (it worked), I went to check my general color settings and found the culprit. My RGB profile was set as sRGB IEC61966-2.1, and I actually needed to use my monitor's RGB profile for it to display correctly. Now that I have switched for this, everything displays fine. I feel a bit dumb!
Thank you very much for your help!
Hi, I work on Windows.
My issue has been resolved by D Fosse, but your answer was helpful. Thank you for your time.
