Projector...... thats the trick. So I have an electric screen that I can roll down or up when not in use. Its pretty easy gettng a projector set-up, and something that once you do and if done right would really change the way you approach content.

Yup, you do seem to need a 4k tv considering how close you sit to the TV. Why don't you go for 46", there are quit a few 4k 46" on the market (i think)

Im probably 50/20 vision or something terrible, but the thing is when i do anything in life i wear my glasses, so presuming the optician is doing there job right i do have "Normal Vision"

i cant really take part in this study, as i do sit about 3 metres from my tele, but sometimes i stand a metre away if its particularly tense action lol 

I might some day.  At the moment, Best Buy Canada's smallest 4K TV is 49 inches.  That's an extra 7 inches that may not be feasible.  And those things are still bloody expensive. About 1700 right now, which is more than I wish to spend on a display right now. I'm pretty happy with my setup at the moment, but when it comes time to upgrade my gaming PC in a year or two, I will see what the options and prices are like. I don't know if my video card could easily handle a 4K resolution right now anyways.

20/20 vision (with glasses) 20/30 without
32'' screen
1920x1080
18-24 inches away

Nice tool, fits with my experiences.

My TV and my projection screen are 2 - 3 meters (6 - 10 feet) away, depends on the seating position.

Blu-ray movies + PS4 games on the 77'' projection screen from the 3 meter distance couldn't be better. From the 2 meter distance they still look great, but could profit from 4K... but without affordable 4K-content (movies and games) I will wait another few years before upgrading my projector.

The same goes for PS3 + 360 + Wii U games on my 47''-TV: flawless from the 3 meter distance, but only "okay" from the 2 meter position. PS2 games (on my PS3) and Wii games (on my Wii U) aren't a pretty sight anymore, especially from 2 meter distance... the resolution above is even a bit sugarcoated, since it's anamophic 640 x 480 stretched to 853 x 480.

The distance to my PC screen varies between 60 - 120 cm (2 - 4 feet)... if I use a gamepad I'm sitting a bit further away. 2560 x 1600 would be nice, but I would need a much faster graphic card for that.

Usually I'm holding my handhelds in a distance between 30 - 40 cm. The Vita screen looks flawless in that distance (some Vita games with sub-native resolution show some pixels), but on every other handheld (and of course PSP + PS1 games on the Vita) you can see the pixel structure. Don't get me wrong, the games are still great fun and while playing I forget the resolution issues most time... but now and then it breaks the immersion.

Moving on to my other mobile devices. I'm still happy with the "ancient" 960x540 resolution of my smartphone, I don't get the 1080p models and higher. Like handhelds, I use it in a eye distance of 30 - 40 cm... perhaps I'm "holding it wrong" and I'm supposed to hold it in 20 cm distance. Tablets i keep a bit farther away (35 - 50 cm)... my first iPad was a bit blurry in that distance, both my Kindle Fire HD7 and my iPad Air look flawless in normal distance.

thats way too far to be for 32inches. should like half that almost.

20/20 vision
55 inch tv
1080P
2.18 meters from screen

Definitely not 20/20 vision (took a snowmobile to the face, once upon a time).

However:
24" Monitor
1920x1080p res
About 36" from the screen

Awesome post!!!!!!

I couldn't figure out how the Hell the site worked, but here's what I'll say. I can tell the difference between 900p and 1080p from more than 15 feet away on a 23 inch monitor.
