Help photoshop colour wrong

Display profile issues 

At least once a week on this forum we read about this, or very similar issues of appearance differing between applications.

Unfortunately, with Microsoft hardware: Windows updates, Graphics Card updates and Display manufacturers have a frustratingly growing reputation for installing useless (corrupted) monitor display profiles.

I CAN happen with Macs but with far less likelyhood, it seems.

The issue can affect different applications in different ways, some not at all, some very badly.

The poor monitor display profile issue is hidden by some applications, specifically those that do not use colour management, such as Microsoft Windows "Photos".

Photoshop is correct, it’s the industry standard for viewing images, in my experience it's revealing an issue with the Monitor Display profile rather that causing it. Whatever you do, don't ignore it. As the issue isn’t caused by Photoshop, don’t change your Photoshop ‘color settings’ to try fix it. 

If you want to rule out pretty much the only issue we ever see with Photoshop, you can reset preferences, I never read of a preferences issue causing this problem though:

To reset the preferences in Photoshop:

Note: Make sure that you back up all your custom presets, brushes & actions before restoring Photoshop's preferences. Migrate presets, actions, and settings

To find out if this is the issue, I recommend you to try setting the monitor profile for your own monitor display under “Device” in your Windows ‘color management’ control panel to sRGB. You can ADD sRGB if its not already listed. 

And be sure to check “Use my settings for this device”.

(OR, if you have a wide gamut monitor display (check the spec online) it’s better to try Adobe RGB instead).

Quit and relaunch Photoshop after the control panel change, to ensure the new settings are applied.

If this change fixes the issue, it is recommended that you should now calibrate and profile the monitor properly using a calibration sensor like i1display pro, which will create and install it's own custom monitor profile. The software should install it’s profile correctly so there should be no need to manual set the control panel once you are doing this right. 

Depending on the characteristics of your monitor display and your requirements, using sRGB or Adobe RGB here may be good enough - but custom calibration is a superior approach.

I hope this helps

if so, please "like" my reply and if you're OK now, please mark it as "correct", so that others who have similar issues can see the solution

thanks

BTW, I wouldn't set color management policies to "convert to working RGB". That's a very dangerous setting, especially if you have layered files. These will change appearance when converting, and you don't want that.

The only safe setting is "preserve embedded profiles". It will handle every file correctly. Preserve is the default policy, don't change it unless you understand the implications of doing so.

Yes, that's the monitor profile. That Samsung profile is defective. Delete it from your system, and replace it with sRGB IEC61966-2.1. The proper way to fix this is to use a calibrator to make a new profile, but sRGB may be close enough for now.

Many monitor and laptop manufacturers distribute profiles through Windows Update. If the manufacturers can't get it right, which happens very often, this can happen seemingly out of the blue.

Sounds like a faulty monitor profile. 

Can you just for testing use the sRGB Profile as your monitot profile? 

And what are Photoshop’s Edit > Color Settings?
