Well, take a look at the first image here:http://www.avsforum.com/avs-vb/showthread.php?t=1202558
Although the actual cause behind the chroma anomaly in that image isn't specifically the same thing as 4:2:2 subsampling, nonetheless what I saw was almost identical. What was ostensibly a one-pixel-thick red vertical line was either thin or fat (and smeared), depending on where it was drawn; as it moved across the screen, it alternated between thin and fat.
Take a look at my idealized simulation of 4:2:2 subsampling, from my other thread:http://www.avsforum.com/avs-vb/attac...1&d=1286786576
This is a close-up of my special modification of the Belle-Nuit test chart. Although the color smearing is not so apparent, you can still tell where the once uniform nature of the red lines has been compromised, particularly where they are separated by two black pixels. Other colors are washed out and bleed into one another. Compare that (on the right) with what was, originally, razor sharp color accuracy (on the left).
It might be best to think of it as part of the technical specs, like so:
* IPS-Alpha panel with true 174 degree viewing
* Full array LED backlighting with local dimming
* Colors are not destroyed
See, without that "feature", colors are destroyed. Is it so wrong to wish games to look as good as the Xbox 360 is capable of making them? Or the PC desktop to be accurately represented, as opposed to, well, not?
