IPS > all other monitors
I hate using my laptop, the screen sucks so hard compared to my desktop IPS monitor.
I would agree that IPS > TN, but both look exceedingly horrible if the backlight isn't up to my high standards. The apple cinema/thunderbolt display (for example) I can see flickering, which is annoying. I can get trinitron monitors for free that can do 85Hz or higher, so until I find a decent flat panel that doesn't flicker on me, I'll stick with my CRT's.
You can also get laptops with IPS displays. I dislike my laptop too. (It flickers, but not as badly. much more of an eyestrain than my CRT, though)
21:9 is a very interesting aspect ratio. I'm used to 4:3, so any widescreen is a bit of a change, but I thought 10:16 or 9:16 was more common. Is this a more movie aspect ratio?
