I have no colourimeter to perform hardware calibration, but while editing some pictures I still would like to be able to get the colours appear at least slightly truthful. I know that every monitor has its own gamut (colour space) it can display and to get the screen colours to show up correctly you need to calibrate the screen.
I have two displays. I think they are both quite ordinary, gamut-wise (i.e. no wide colour gamut):
The first display has a manufacturer-supplied ICC-profile, which was automatically downloaded and set by the OS (Windows 10), I believe.
The second display does not have a manufacturer-supplied ICC-profile, although it has a "sRGB mode". The monitor came with a calibration report, indicating that in sRGB its delta-E is lower than 2. When setting the "sRGB mode", the brightness and contrast are fixed at the levels 70 and 50, respectively.
So for the first display, would applying the manufacturer-supplied ICC-profile provide colours that are in the right ballpark? Why or why not? Does theory deviate from practice here and why?
- If indeed this is the right thinking, what colour setting does the monitor need to be set through the OSD-interface using the buttons on the monitor itself (or through DDC)?
- If this does not work like this, what is the purpose of a manufacturer-supplied ICC-profile?
For the second display, does setting the sRGB-profile provide a semi-adequate sRGB gamut output for the monitor? So by setting an sRGB (ICC) profile for the screen would make it output semi-adequate colours within the sRGB space (or by setting no profile at all since presumably sRGB is assumed standard by the OS)?
- If indeed this gives kind of the right colours, what happens internally when using the screen's "sRGB mode"?
- Note: the question over here indicates that the function of the sRGB mode is to use a standard sRGB gamut when your monitor natively displays a different gamut, so as to adequately display non-colour-managed applications. This question is related but asks if using "sRGB mode" may be used for colour managed purposes.
