Hi,

I guess that would not be useful, since I only use this hardware
chain, and since that other clipping most probably occurs in the
monitor, not at an earlier stage, the results would be the same.

Yes, that would be great, but I only use PC levels now. A new 8-bit
monitor would be a more permanent solution.

Still, my curent profiling attempt shows that the LUT box can actually
handle the CM process quite well for TV and PC range. I only have to
figure what I did wrong previously to get the clipped whites in the
previous profiling instance. I don't think I have the knowledge,
though.

Right, my bad. :)
