OK so we are jumping the gun on this a little but I thought it merited a little post. I am writing this back in January (the day before your prelim) and I am guessing at where we will be today.
Screen resolutions for television have traditionally been described in terms of the vertical pixels, 576i, 720i, 720p, 1080p but the new standards are now describing them in the horizontal. So a 4K UHD (Ultra High Definition) screen has in the order of 4096 horizontal pixels this is twice the resolution of 1080p HDTV (High Definition TV).
