Wrong colors in LR6

[larsj61927084]

I have two computers where I run LR6.13. It's been whithout trouble for years (from LR2 onwards).

Now suddenly the folowing has appeared: On my desktop with WIN 10 the print-module produces wrong colors. When I try to print on paper or print to file the picture get a strong magenta-cast. In all the other modules it looks ok.

The strange thing is that I posted a magenta-colored JPG in an online-forum (Swedish Fotosidan.se) and there it looked ok.

On my laptop I run WIN8.1. On that one the develop-module behaves strange. The background is purple and the preview looks like a psycedelic poster from the seventies. All other modules behave correctly, and I can even edit and print with good result.

Someone who has experienced this, and know what it might be?

Lars,

On your Win 8.1 machine, you need to go to the Performance tab of Preferences and turn off the checkbox for Use Graphics Processor.

On Win 10, you probably have a corrupt monitor profile. If you don't have a hardware calibrator, try setting the default profile to sRGB until you do get one.

The Graphics accelerator did the trick on the Win8.1-system - thanks

On my WIN10 it's another question. I tried the Graphics accelerator there to - no success. I swiched to sRGB-profile on my monitor ass well - just to be shure - no success.

My own suspicion is some kind of conflict  WIN - LR6. There was a big uppdate on Windows last week. I have erased all ICC-profiles from the color-folder and reinstalled my printer-driver, I have tried managed by printer-printing but with the same result.

I will try reinstalling LR next week (for the moment I have no internet-conection on that computer).

A colour cast on prints is often the result of managing the colour in both the printer driver and Lightroom. Make sure this isn't what you're doing. See here:

In addition to what Hal already said, here's a guide how to check for a corrupt monitor profile: https://www.lightroomqueen.com/articles-page/how-do-i-change-my-monitor-profile-to-check-whether-its...

Thanks for Your answer - I tried, but it did no difference.
