The monitor has extreme IPS Glow (shine through the backlight) in the lower left corner, which is extremely visible in darker image contents. I had let me provide a replacement model, but again hardly any differences observed. But who would not darker games or movies will look at it with the monitor safely have his joy. I played on Battlefield 4 and it was great! The format is just great.
I find it a pity that LG has not so good the IPS Glow here under control. Especially because it was quite ok in 3 of the 4 corners. But with 3 tested models always of itself IPS GLOW in the lower left corner shows not just a great quality control at the factory.
