good luck getting a accurate mage on these via flame .
Imho flame is incompatible with XDR in all my testing… as XDR requires specific input metadata to make their reference modes work - which flame does not provide to macOS, now that might have changed with recent flame releases or whatever.
But flame would need to send proper “rec709” metadata to the xdr monitors and then you can enable rec709 reference mode.
In my testing flame would send no such metadata, causing all UI elements to he intepreted as “Display P3” so everything was over saturated ,and the wrong eotf, which still looks to be true on all my macbooks, nuke has the same problem, only resolve you can click a button.
Bascially flame viewer has to 1:1 match quicktime with a 1-1-1 (Colorsync compatible turned off)! prores. otherwise its incorrect
Interesting. I only did testing by eye. but the new XDR in P3 mode next to my Sony BVM looked exactly the same straight out of the box. and then to the suite that has the Flanders XMP 310 - recently probed. looked exactly the same. so I thought all was good. and in fact when I replaced the Flanders with another XDR I didnt notice any difference - if anything the lack of glow and better black levels I preferred. all done by eye though.
I went back to one monitor in the end. not sure I liked using two! Wacom was too widely spread and I ended up with a crook in my neck. Using the new Studio Display XDR on 5K mode and it’s great.
tablet resolution is an issue. I have used medium tablets of up to 5K pixels horizontal, but once you get 4K and 5K per display even just holding the pen still results in multi-pixel jitter that gets in the way of double clicks, etc. for a while i had a large Wacom to help. It was ok, but not great.
one work around is to use pen for pointing and express buttons for clicks. Something to be said for that in general, but different muscle memory.
