Well I've got it running. I've received the panel back that I sent to them.
I've got Firmware 2.1 all seems good so far, haven't got any of the green sparks on my work machine, but I wont know what it's like till I get it plugged into my home machine and do stuff I know will give me them.
I'm impressed with the backlight reduction, but the left hand side seems brighter than the right, but at least my white haze has reduced
I have one major issue with my screen, and that is the appearance of damage on the back of my stand the vertical bit facing away from me. Looks like it was dropped on something and there is an inch x inch set of indents (dints) in the aluminium finish...
I think I'll be sending them an email and asking that they send me a new stand.
I can't see the damage from where I'm sitting and it hasn't affected the actual panel at all, but I really don't expect companies to damage screens and send them back without saying anything. I'm expecting to keep this screen for a while now and don't want any marks this soon after getting it :/
