I have two monitors on one PC (extend option). The colour for two monitors are different, how can I make the colour settings.
E.g For monitor A, the colour is as shown in the below image
and for the monitor B, the colour is as shown in the below image
Have you noticed that now you've posted these 2 pictures to the same web page... they now look identical? [They are identical, pretty much to the digit]
Most consumer-level monitors [& especially laptop screens] are shipped with monitor calibration that looks attractive on display in the shop, but the first thing you have to do when you get home is to change it from attractive to accurate.
To do this properly, you need a device called a colorimeter. These vary in price from entry-level at maybe $£€ 80 up to several hundreds.
Without one, you will never know when your pictures are right.
Very briefly - you connect it to USB, hang it over the screen, blocking it from other interfering light sources, & run the software. It will tell you exactly what to do. It will then generate a profile [LUT - Look Up Table] for your screen & tell your computer to apply it.
You can now see what colour things are supposed to be.
There's an in-depth tutorial at B&H - How To Calibrate Your Monitor which includes links to some specific colorimeters.
There is an additional complication that sometimes arises on consumer-level graphics cards, especially apparently on Windows.
The OS & graphics card must be able to simultaneously support 2 LUTs. I don't know how to test for this on Windows with dual external displays.
