[Leica] question about image viewing and profiles

[Tina Manley]

I have exactly the same monitor - Eizo ColorEdge CE240W - and I'm using
Windows 10.  I can't see any difference.  At first, I thought the second
one was slightly better in the shadows but I enlarged it and decided it was
my imagination.  They look exactly the same.
