No, I just recently got this one, scan lines in the top right corner.
When lightboost is enabled the scanlines are unbearable.. So in short, lightboost is screwed with that monitor.

No idea which 144hz monitor you're talking about :(
But the BenQ XL2420TE is from what I have heard an amazing screen with nice colors, thought it is quite expensive(a lot actually).
Sounds like you just had shit luck, just RMA it.
