That's must be really frustrating! Yeah I don't know, if I can't match it then just rely on my Macbook and edit the colors I guess lol. Here tho the colors are not super "far off" but if you're very perfectionist with colors it might also frustrate you.
What do you use now?
It was frustrating. Trying to get green leaves that looked bluish on the other screen was annoying.
I have Ugee m708 that doesn't have the screen (cheap and simple :D ) and somehow it is easier for me to use.
