In 1993, Texas Instruments built a 2048x1152 DMD prototype. No rationale is exposed in the papers for choosing this specific resolution over the Japanese 1035 active lines system, or alternatively doubling the 480 lines of the standard US TV to 960, but that way it could cover all resolutions expected to be present on the market, and that included the European one, which happened to be the highest. Some legacy of this development may be seen in "2K" and "4K" digital movie projectors using TI DLP chips, which run a slightly wider than usual 2048x1080 or 4096x2160 resolution, giving 1.896:1 aspect ratio without anamorphic stretching (vs the 1.778:1 of regular 16:9, with 1920 or 3840 horizontal pixels), give a little (6.7%) more horizontal resolution with anamorphic lenses when showing 2.21:1 (or wider) movies specifically prepared for them, and further enhancement (~13.78%) through reduced letterboxing if used "without" such lenses.
