Yeah, twice the vert and twice the horiz means 4x total...

 Also, I don't understand how they can do this?  160 deg viewing angle and still tagert different eyes??  How far away can you/how close do you have to sit?  The only way that makes sense to target different eyes is with parallax effects..  Seems like they will have to restrict angle or viewing distance.. i just dont see how it will work in the maintstream..

i'm confused, isn't 3840x2160 actually twice the resolution of the highest HDTV standard of 1920 × 1080?

3840x2160 produces four times the pixels of 1080p:

3840 x 2160 = 8,294,400 pixels

1920 x 1080 =  2,073,600 pixels

8,294,400/2,073,600 = 4

well i get how the math works out, it just odd how twice the resolution turns out to be 4 times the pixels. i mean if you add up the pixels of two 1080 hdtvs, you get 4147200. they cram double the resolution in this 3D monitor and use some sort of parallex effect so that each eyeball sees its own seperate 1080 image, so why would they need four times the pixels?

and, with 4147200 pixels at a 16:9 aspect ratio, what resolution does that come out to be?

My impression from the article is that the 3D effect and the resolution doubling are two completely seperate features.  It has 2 times the resolution resulting in what is effectively 2160p, which has the same aspect ratio and 4 times the pixels as 1080p, and also does this 3D whatsit.  Which I would definitely need to see to believe it.

Its 4 times the pixels because its twice as many in 2 directions, twice as many high and twice as many wide.  So 2+2 = 4. :)

I knew that. I did! I just hadn't had breakfast is all. Anyway thanks for clearing that up Tekzel. And sasquatchua, how dare you question my leaps in technological understanding. My assumptions are entirely plausible. I'm back baby , I'm back! Goddamn this is strong coffee.
