Ultra High Definition TVs. The current units are described as "4K Ultra HD" which is 3840 pixels × 2160 lines and has four times as many pixels as the current 1080p HDTV standard. There is little video material available to this standard, but I suggest it would be worth looking at using these screens for some smaller meeting rooms and offices. The 55 to 65 Inch UHD LED TVs are currency priced at about $5,000 US. Prices are likely to drop rapidly, as has happened with other flat screen TVs. This size screen could be attached to the wall for a group of about six people. Rather than having the screen high up on the wall, I suggest placing it no more than 300 mm above desk level. When not needed for a group the screen can be used by one person, with a desk pushed up against the wall to provide an ultra-large display.
These screens could also be used in academic offices. One person could use the TV as their computer monitor and it could be used by a small tutorial group. This might suit an arrangement where offices are sized to accommodate one professor (with a meeting table), two lecturers, or four tutors.
