Blacks and shadows are blue in develop module.

[bengunn57]

I'm using a 2016 Macbook Pro with LR 5.71 and since LR5 I have had the same problem with darks, blacks and shadows, showing as blue in the develop module. I use a Canon and shoot in RAW, so I'm trying to edit DNG files. How can I fix this? other threads say goto preferences and performance then turn off the GPU but my screen does not have a performance tab. What should I try next

DNG of the moon

Press J once or twice, or click the white triangle in the histogram top left. This is the clipping indicator.

Thank you So much for this anwser... The simplicity is as exciting and the lack of Any other anwsers is infuriating.

Or you can adjust blacks and shadows as well as the  dark end of the tone curve until the blue disappears.

There's nothing to fix. Highlight and shadow clipping indicators are a feature in Lightroom for you to use
