First, just to rule it out, make sure you have the same color settings. The really important thing is to have Color Management Policies set to "preserve embedded profiles". With this setting, the embedded document profile (whatever it is) will be correctly handled and displayed on both systems.
But I'm more inclined to think you have a broken display profile on your work machine, especially if only Photoshop seems affected. Photoshop is likely the only application that actually uses the display profile.
All this assuming you don't have a wide gamut monitor, which changes the playing field a bit.
Anyway. To test the display profile, set sRGB IEC 61966-2.1 as display profile in Control Panel > Color Manangement > Devices (Adobe RGB if wide gamut monitor). Relaunch Photoshop so that it can pick up the new profile at startup.
Do this on both machines. If they now display more or less the same, that's definitive confirmation. The real fix is to make a new profile with a calibrator, but if you don't have one, just use sRGB until you do.
That worked wonderfully! I'll make sure my computer at home is using the same display profile after work. Now I can colour correct my files!
Thank you so much!!
You're welcome .
This is in fact a very common issue. Monitor/laptop manufacturers who really should know better keep pushing these bogus profiles onto unsuspecting users, often through Windows Update. I have no idea why they keep doing that, or why Microsoft allows it.
As I said - if you don't have a calibrator, just use sRGB. You're much better off with that.
