Well I have decided to keep mine, I just can't be bothered to faff around with returning and having begging them to refund instead of replacing.
Before, I had some settings that stopped the pops happening as much, but it always felt like I was compromising the picture quality to hide the pops. Now I have found a setting that keeps the brightness pops down (don't get me wrong, they are still visible but not as much) and for me, the picture quality is nearly spot on.
Let me know if anyone wants me to share these settings, I must add people will probably hate them but I find them fine
-edit-
What sharpness do you guys have it on? I can't really decide if I should have it low (in the 30's or have it around 50)
