There really needs to be an international standard for these terms. What's wrong with listing a display by its capabilities? 1920x1080 60hz 24bpp. That way we can get rid of all this HD, HD Ready, UHD, 4K nonsense. It's marketing speak only meant to confuse you into buying something you wouldn't have if you were better informed.
Listing by megapixels would make me happy. The number of diagonal inches has been the least helpful indicator of screen quality over the last decade, and the WUXGA nonsense is too hard to keep track of as well. Adopting a MP number would do more to get us high res screens than any other change.
