Yes, I assumed as much. I was just profiling it so that it would look
closer to the other screen as they're side by side. I only really do
color work on the Dell.

How do you pick the 6000K though? The laptop has no adjustments. And
the matrix profile resulted in horrible brown blacks when I did it
before. What would I do differently so it doesn't happen?

That's pretty much the point really.
