Hello! I am just discovering the world of calibration with an old Spyder3 Pro which I borrowed from work.
I have a Philips 278E1 (4K IPS) and a Gigabyte G27QC A (WQHD VA) monitor and I calibrated them with the same settings. But the Gigabyte monitor has a way larger gamut showing on the profile information window, how do I manage to match the Philips one? sRGB mode in the monitor OSD?
Well, comparing the two monitors while looking at images, for example with brown skin tone, the color on the Gigabyte monitor is way more saturated and on the Philips monitor brown just looks like natural brown!
Image attached, top one is Philips bottom one is Gigabyte. Thank you!
Oh I figured it out… Seems like irfanview has the option to enable a color profile and the one monitor assumed the same profile as the other one so it looked off!
Install Irfan plugins bundle, then turn on color management in settings. May be you need to set total sRGB assignement for images cause Irfan ignores profiles in PNG files.
But there are another serious problems:
- You can’t see the same color with two different displays that have significantly different RGB spectral curves (we see different RGB promaries – corners at gamut diagram). Metamerism does it job. Even white point may have different tint. I recommend you to use one display as reference for 6500K, and set white point for the second one by you eye (press WP coordinates selection icon).
- Your display don’t cover even sRGB together. So, hope to see correct colors in gamuts intersection space, deep blue jeans are away.
- Use relative colorimetric intent in applications like GIMP for display profile, set it as profile default if you build XYZLUT-based profile (gear icon in profiling tab), set it for intent in Firefox (about:config in address string, search for “gfx.color”, gfx…intent=1) and set Forced color in Chrome (chrome://flags, serach for “color”).
- Windows/MacOS applications start at main display (can be changed in Display settings), so they get its profile. If you move application to the second display, application doesn’t change working display profile (Ps shows that it changes at Mac, but actually it doesn’t). If both displays are of the same model and profiles contain calibration part this does not matter (“LUT-part” is the same in both profiles, calibration is applied by videocard). but for different displays you may only change main display before starting Lr, perhaps, to use it at the second display after Ps started at the main display. Or to set second display profile for the main one before you start Lr. Turn all back after applications had been started.
For serious graphical work use two displays of the same model and with separated RGB curves (PFS lighing or similar, usually not specified by manufacturer, search for tests and recommendations) to avoid color cast.
