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.
