I have not kept up on the details, but the last I read, the 1920x1080
DLP chips were going to be 960x1080 actual mirrors. They use 1 mirror to
generate 2 pixels by flipping the mirror at a high speed between two
different angles to control 2 pixels on the screen. TI does this with
their lower cost 720p chipset which is 640x720 mirrors; the more
expensive HD2+ is 1280x720 mirrors which are generally regarded as
providing the better picture. Check the RPTV forum on www.avsforum.com,
should be more detailed info there.
