40" TV, 1080p, about 5 feet from the tv, equals about 57.



 Been away for a bit, but sneaking back in.

Gaming on: PS4, PC, 3DS. Got a Switch! Mainly to play Smash

I'm just waiting for a time when we won't have to think about this anymore (angular resolution > 200).

According to the first chart I can see up to 1080p on my 32" 1080p TV from 6 feet away. According to the second I can see up to 8K.

Yeah, the high resolution on the new iPad is gorgeous, I want a higher pixel density on my tv so when 4K become affordable I'll get one.

Pixel density and screen size are not the same thing nor are they interrelated. If you can fit more pixels into the same amount of space then you can achieve better resolution without increasing the screen size or pushing back the viewing depth.

There was a time, back in the 1980's and 1990's when the size of the pixel was just as if not more important than the screen size. LCD monitors essentially made that conversation moot as they tended to be uniform and much smaller than CRT monitors anyhow.

Well im to lazy to use a calculator and to exactly find out how far I am away from my screen but. Im playing and watching movies on my 2 meter wide screen. In 1280x800.

Its awesome and its more than enough. I had a 42" FullHD TV and I am glad I now have this screen. I returned the TV after 2 years of use and got full refund xD
(they sold me the wrong model in the first place and I used it and waited almost 2 years to complain So i got a TV rented for 2 years for free)


The problem is people and technology are not able to see/reproduce motion resolution of 1080p let alone 4k etc. So there is no point in a 4k display unless you like slow motion and images. (guess why they use slowmotion to demonstrate fullHD material on full HD tv's)

Alot of movies also have static images and slow moving characters in close up / conversation scenes. But this is really rare in games so whatever.

This is almost scary!

You can see almost anyone in the whole stadium. Good for picturebook memories I guess, and for big-brother too.

Anyways, I'm all for the advance in tech and if it can make one feel more like they're there, I'm all for it.

There might be something wrong with your formulae. I'll check it out later and post here.



Hynad on 25 August 2012

What I wish to get is 300dpi on a 32". I use a 1080p 32" as a PC monitor, on which I draw on Painter and Photoshop. So the added pixel density would be Godsent to me.

OP: 43.2 at roughly 3 feets away from a 32"...  I think your formulae is erroneous.

Since you are talking about resolutions and tv´s, you might find this interesting:

 

TV with 16 times resolution of HDTV passed by UN's ITU

 

Ultra High Definition TV, with 7680x4320 resolution and 120 frames/sec, was approved by the International Telecommunication Union

By Jay Alabaster

IDG News Service - A new television format that has 16 times the resolution of current High Definition TV has been approved by an international standards body, Japanese sources said Thursday.

UHDTV, or Ultra High Definition Television, allows for programming and broadcasts at resolutions of up to 7680 by 4320, along with frame refresh rates of up to 120Hz, double that of most current HDTV broadcasts. The format also calls for a broader palette of colors that can be displayed on screen.

The video format was approved earlier this month by member nations of the International Telecommunication Union, a standards and regulatory body agency of the United Nations, according to an official at NHK, Japan's public broadcasting station, and another at the Ministry of Internal Affairs and Communications. Both spoke on condition of anonymity.

Japan has been pushing for international approval of the new format, which was designed and developed by NHK. It is hoped that international adoption will give the country an advantage as television progresses to the next generation. NHK has stated that it hopes to begin widespread trial broadcasts of the format, which it calls Super Hi-Vision, by 2020.

The standard also includes a smaller layout, which is 3840 by 2160 pixels. The two arrangements are commonly referred to by their horizontal pixel counts, or 8k and 4k.

A document posted by the ITU earlier this year said the same standard will be used both in living rooms and broad public spaces, including the large screens used in movie theaters and sports venues.

NHK and Japanese electronics makers are still working on their implementation of the format, tackling issues such as the high-speed compression needed to send it over the air, the vast storage requirements, and technical issues with developing advanced cameras. The resolution is so fine that cameraman using equipment with HD screens can only see 1/16 of what they are filming.

International standards on audio specifications as well as broadcast formats have yet to be passed. NHK is advocating a 22.2 multichannel audio format.

Yesterday, LG announced it will soon begin sales of an 84-inch TV capable of showing 4k for about US$22,000, though the company admitted there is still little content available at that resolution. During the summer Olympics, NHK together with British broadcaster BBC showed parts of the event using the 8k format.

Japanese electronics makers such as Panasonic and Sharp have also showed large-screen UHDTV sets. Sony and JVC have released 4k projectors.
