Nicholas,
as I replied to your email, I personally checked your unit before it was shipped back to you.
It was actually put on test for a few days after repair, and the display was working flawlessly.
There was no dent (or "bent" metal as you mentioned in your email) , nor scratches, other than a tiny paint chip on the very edge of the armrest (as it was when we received the unit).
I therefore suspect that it was damaged in the return UPS shipping.
Please continue this communication via email with Arturia US to get it resolved.
Sean
