That all depends on your viewing distance. My monitor is 24" and runs natively at 1920x1200. I can guarentee that at the metre or so I sit away from the screen there is a noticeable difference between 1920x1200 and 1680x1050.

Anyway, the reason this camera (and all high end digital film) is for when you project it onto a giant cinema screen. It is also this high because when applying effects you want the extra resolution. 4k and 2k transfers are the norm in the industry. Generally, the extra resolution allows for better sub-sampling, which is exactly how full blown, AA, motion blur, shadowing etc... works when raytracing. Exactly the same reason why high end audio apps support 192khz 32-bit sound.

HDMI v1.3 already supports 1440p

hell, my local theaters don't even have 1080p projectors... many don't

 What are you talking about? This will go perfectly with ten thousand inch television. 

Mine don't either Vizunary (well one does, but it was only recently added). This is scary lol.

Man, I miss Beta...

I'm in love

This is exactly why nothing can be "future proofed"

 Is 1440p 1440 x 900?

If so my Pc can support that with Galatic Civilations II. Or were you talking about consoles only?
