I will certainly try to get on that over the long weekend I did manage to do a bit of side-by-side with the two tonight, but no chance to take pics or make a video yet.
That said, here are my impressions so far...
On closer inspection when I got everything set up at home, I can spot two issues with the panel I didn't see at first glance.
Firstly there is a definite back-light bleed in the top right corner which looks pretty bad when any dark image is on the screen in a low-light room. It's not terrible by any means (I have bought supposed A/A+ panels locally with worse ... *cough*ASUS*cough*) but it is there and noticeable on a dark screen. I can't see it at all in normal use without really trying hard to look.
Secondly, on a pure white screen the bottom 3rd of the panel has a slight yellow tint to it. Again, this is not something you would readily notice unless you were in the right conditions and specifically looking for it. Really though, I don't care about either of these issues. Sure I paid over $400 for the screen which might seem like a premium, but considering the screen size, resolution, panel tech and connection options, it's a steal. Realistic expectations are very important with these screens I feel, and I'm very happy with my purchase despite its unwanted extra "features"
Side-by-side with the U2412 there was a big difference. I calibrated both simply using the Windows 7 colour calibration tool and eyeballing it (no technical wizardry here! /spits into fire) The Dell seems to have nicer uniformity on whites and less back-light bleeding, but that was the only two things I could say were better vs the CrossOver. Using 1920 x 1200 feels TINY after even an hour at 2560 x 1440! I really get what people mean when they say that 16:9 vs. 16:10 means a whole helluva lot less at this screen size and resolution.
The CrossOver is bright and very crisp with great colours. I'm not sure how accurate they are even after my colour lolibration attempts, but I knows what I likes and I likes this. The Dell, by comparison, looks perhaps more accurate in terms of the colour, but it looked a bit flat and lacked the "pop" of the CrossOver.
Rather than Wall-o-Text everyone to death I will simply say that, despite the defects, I'm super pleased with the screen. The image quality is absolutely fantastic and precisely what I was looking for in a new monitor!
