I don't think you'll l have any luck as I did test other ADCC monitors and none of them had this issue. The key is the combination of ADCC and panel. I don't think there's anything wrong with the panel itself. If there was the VS model would've probably behaved the same.
In a nutshell: I think you'd have to look at either Samsung 214T or Nec 2170NX.
If you ever get a chance to see them, or have any new information please post it here. Until then let's just enjoy the holiday season:
Merry Christmas & Happy New year!
