Image compression effects

This article is mainly concerned with pixel size and the resolving power of human sight. However, image compression effects could have a greater influence, especially where image resolution and screen resolution do not match. A 1080p screen will give a very clear account of a 1080p bluray signal, but will give a very blocky version of a PAL widescreen signal. The consequence will be that the optimal viewing distance for an HDTV fed with a standard definition signal will be very much further than a high definition signal.--ML5 (talk) 14:06, 16 August 2010 (UTC)[reply]

Peripheral Vision

Missing in this analysis is consideration of peripheral vs. central vision. The former may be particularly influential in creating presence. With too wide a visual angle, the most meaningful material in a scene may lie in the peripheral region, requiring a great deal of eye-shifting to take it in; with too narrow an angle, peripheral mechanisms may be inadequately stimulated. This article needs some exposition about all this, but I'm not qualified to find sources, let alone evaluate them. Myron (talk) 06:49, 7 February 2011 (UTC)[reply]

There will be very hard to find sources on which distance is best for people, because some people like myself prefer to be as close as possible without seeing pixels. It is like asking which ice cream is better chocolate or vanilla. I think close as possible is best, as long as comfortable. (NICKJANSSEN)

Clarification

The recommendation section should make it immediately clear that the relationship bewtween screen size, viewing angle, & distance only applies to 16:9 screens. While these are now ubiquitous, there are HD monitors that are 4:3, and 4:3 content will be viewed on 16:9 screens. — Preceding unsigned comment added by 70.39.231.44 (talk) 21:41, 5 March 2013 (UTC)[reply]

Units

Please use ft & inches instead of decimal point feet (e.g. 5 ft 3 in instead of 5.25 ft). Unfortunately, in the US, many measures do not indicate metric units. Instead, they indicate ft and inches, not decimal point feet. --Makkachin (talk) 12:11, 8 September 2013 (UTC)[reply]

Toshiba recommendations

The Toshiba recommendations listed in this article do not agree with the actual recommendations on Toshiba's website. --JHP (talk) 01:31, 15 November 2013 (UTC)[reply]

Human physiological considerations

The author states "a wide field display" causes undesirable physiological effects. But in the same sentence the author states "the feeling of presence can be too real". In my experience, the most common cause is hand-held camera shake, which is hardly considered "too real". I think it would be better to give the standard definition of increasing the visual angle can cause miscues between what the viewer sees and what the viewer feels through their balance system.
