I'm looking to purchase an XB321HK. I know there are complaints about flickering/artifacts. There's numerous clips showing this particular issue. Acer initially left customers with the impression they refused to acknowledge the issue but seemed to have adjusted their stance. All good, no need to get back to that.
My questions at this point are:
1. Do all XB321HK suffer from this issue or is it traced back to particular production batches/lots?
2. If I buy one off Amazon (UK) at this time, can I be sure it's a recent enough model to not have this issue?
