is this problem also there if you just shift like a few pixels off center?
Warranty would be 1 Year standard, or longer, depending if you got Upgrades when buying it.
But i am really not sure what would qualify for Warranty Repair/ Replacement, if it comes to stuff like that.
Here in Germany (and probably same about everywhere else, where just driving there and just giving it to them wouldnt be possible), you would pretty sure need to send it to them for Replacement or Warranty.
Back when i broke my BNC
https://forum.krontech.ca/index.php?topic=602.0 I also asked them how a repair would be done, and i would have had to send it in to get it repaired. Thats one of the Reasons, why i just ended up trying to repair it myself, which worked well for me. The Replacement Part i put in there literally cost less, than what Shipping alone would have cost.
So for this, i am Pretty sure, if this is covered by Warranty (my BNC probably would not have been, because i was just stupid and Dropped the Thing, which isnt exactly Krontechs fault...), that you would still need to send it back to them.
