Monitor arrived, unboxed and plugged in. All the reviews are right, out of the box the brightness is somewhere the wrong side of looking directly at the sun. After setting the desktop resolution I reduced the brightness to 10/100, then further to zero. Yes, I put brightness to minimum to get a comfortable level. I think the high brightness is more suited to a TV application than a monitor.
Still have to fiddle with the colour/contrast/etc. to get it "just right". The colour evenness reported seems to affect my sample. The right third of the screen has a faint but just noticeable warm tint compared to the mid and left thirds. Will see how that goes.
Other quick impressions are - have I gone too far? While I welcome the resolution, I think I would have preferred a smaller surface area. I didn't tidy my desk so it doesn't fit in the gap left by the old one, and is higher up to clear the space than I'd normally have it. I need more space to the sides.
