That sounds about right

32" 1920x1080, that's 1920 pixels over a width of 32 * (16 / sqrroot ((16^2) + (9^2))) = 27.89" wide
From 3 feet away 1 degree covers (3*12) * tan(1) = 0.628"
1920 * (0.628 / 27.89) = 43.2 pixels in 1 degree looking dead on at the screen.

300dpi on a 32" that's over 8K or (300*27.89) 8367 pixels horizontally. That would give you 188 pixels per degree in the center. Close to the limit at human vision of 200 pixels. That would be ideal for drawing on a 32" monitor from 3ft away. It should be possible since they can already make 440dpi 1080p panels.

The room full of Movies, TV broadcasting and Gaming content available to consumers in 4K and 8K by 2017

I would like to own a 8K TV though, to compensate for my uglyness.

You are partly right about the moving images with 1080p. Blu-ray and especially streaming content and tv broadcast use way too much compression for moving images to look good. Slow motion is neccesary otherwise half the olympic efforts would not be vissible at all in the so called HD broadcasts. Analog tv looks better in motion then the 6-7 mbps mpeg2 1080i broadcasts we usually get.
Blu-ray at average 30 mbps is still compressed down to 2-3% of the original data stream. Pause any heavy action scene and the result is closer to 480p.

Gaming at 1080p RGB looks a lot clearer in motion then any blu-ray film can provide. No compression, full color reproduction, 60fps. I can definitely see the benefit in motion from that.

The first available 4K movie runs in Cineform format at average 300 mbps, 10 x blu-ray. (also higher color depth and less chroma subsampling) That should look way better downscaled to a 1080p display as well. A new movie format is ofcourse an easier sell if it has a better max resolution. Personally I would already jump on 300 mbps 1080p content without chroma subsampling.

There are other small advantages to 4K displays. More pixels reduces artifacts from the display and upscaling 720p to 2160p works better then to 1080p.

``Don't know what a calculator is`` is winning with an amazing 40+% lol.

My current TV gives me 75.78 at 720p.

Some time in the next few years I do want to upgrade but not to a massive TV 5-" would be good, but according to the calculations if I go up to 50" 1080p I will get slightly lower ppd (~73) than I currently do with my smaller 720p screen. However if I go to a 46", which is substantially larger than my current TV then I get a bit of a bump with 88.24. So unless I go 4K on any TV above 46" then I'm not really seeing any visual fidelity benefit out of a larger screen. Because 4K will be well outside my budget for a long time to come, possibly the best combination of improved visuals and decent sized picture is a 46" 1080p screen. Which is interesting because I always thought 46" was the right fit for my lounge.

I'm not mathematical!

2017? Actually you could play GT5 prologue in 4K in 2008.

With 4 ps3 linked together and a $80k projector at the time. The projector has come down to 25k, still a ways to go before it becomes affordable.

It's not happening as fast as people thought back in 2008.

The 4K resolution development will follow the trail left by HD, FullHD and many others before: CES #1: Prototypes, CES #2: First Devices, CES #3: Mass Production, CES #4: It is everywhere. CES 2008 saw first devices, CES 2009 will witness first production devices, CES 2010 will see Samsung, Sony and other heavy-weights launching 4K LCDs and by 2011, 4K will be everywhere.

We're in 2012 now, 2 years behind. At around $20k for 4K displays the heavy-weights are just launching their first 4K tvs.

You can already enjoy current pc games at 4K. The common method is to render at 3840x2160 and downsample it to 1920x1080. Also called uber or super sampling or by the old name 2xfsaa.
A modern GPU like the Radeon HD 7970 can output 4K over HDMI. The only piece missing is an affordable 4K display.

Btw I see great potential in that room. Add a wood floor and some curtains for accoustics and hang a big screen on that left wall. Looks big enough for a 120" screen.

8K only? I game at 1080K!
