Long, long ago, I described “my dream monitor” here, in terms of a newly announced (in 2007) 52” 4K TV. My take at the time was that it was maybe a bit big (the corners would be hard to use) and maybe a bit low-DPI, but overall it’d be a great improvement over the 24” 1080P screen I had at the time, although connecting it to a computer would be a bit entertaining.
