Dual monitor(laptop internal and external) color profile loading problem

[Alessandro]

Hello,

I have set up an external monitor(I do not believe it has hardware LUT, it´s a LG 29UM67) in a laptop,  and the color management is not working well, apparently it applies the same icm profile for the two displays, so the colors are way off in one of the displays at a given moment.

The laptop has a nvidia gtx650m and it´s running win8.1, so I don’t know if it´s is capable of loading separate icms for the two displays, but I tough at first that it should be as it seemed something a lot of people do.

Something that I think is not normal, when the LG driver is installed, the internal display reports using the lg driver as well, opening windows color management also report 2 LG displays with the same name. The calibration problem occurs independent of the driver used.

Something seems off here… any clues about what is going on?

Hi,

verify that the right profiles are assigned in Windows color management settings.
