Hi Massimo,
just did a more extensive comparison check on both monitors (with your VVS website and some threads from this forum) and can report that this problem is most pronounced with lighter brown shades (the AMT-1/A-21 family). These appear much more grey on my monitor. A noticeable, but not as massive difference also plagues the very light (olive) green shades - like in the relics labeled U-2 and Pe-2 in this thread. The lighter they are, the more sandy/yellow they look.
Especially crazy were the differences in the depiction of the first two color chips from this thread: http://massimotessitori.altervista.org/sovietwarplanes/board/index.php?topic=1585.15, FS 20324 and FS 20372. On my "bad" monitor both look like concrete, 20324 a little darker and with a reddish hue. On my other monitor they appear as a "normal" medium brown and a sand color. One should keep that in mind when speculating about AMT-1 and its derivatives. I will definitely cross-check all these light brown/olive colors in the future on different monitors.
But: Everything else (Like the green-black LaGG-3 here https://massimotessitori.altervista.org/sovietwarplanes/pages/colors/1941-43/1941-43.html. Each photo with AMT-7/-11/-12 as well.) looks more or less the same.
Cheers,
Christian
