That is pretty terrible, the last restock for this monitor came and went (16/05/14) but I unfortunately was not far enough up the queue to have my order fulfilled.
If I receive a monitor that looks even remotely similar to yours in terms of backlight bleed/IPS glow it will be going straight back.
I hope Overclockers are straight shooters and return that panel of yours to LG for replacement rather than send it out to a customer like myself. It is entirely too much money to spend to receive a used and most likely faulty unit.
