Got one of these yesterday and must say I'm very impressed. No dead pixels or other defects and it's really nice to have the blacks back!!
If you get one of these and don't wish to fart about too much then set the colour profile to Medium and the Gamma Mode to 3 and put 60-65% setting into Digital Vibrance and it's pretty much bob on imo! Adjust Brightness and Contrast to suit
I'm still waiting for those reviews from tftcentral/pcmonitors before I order but first we need LG to send those review samples out to them...
