DLP projectors (especially cheap models) sometimes cause people to see the “rainbow effect” – a rainbow streak accross the screen during some content – but this issue has been reduced significantly of late in single-chip DLP projectors and completely eliminated with 3-chip DLP projectors. LCD projectors have historically had low contrast images with contrast ratios of 500:1 or lower but recent LCD models have had ratios of 4000:1 and higher, exceeding many DLP specs. LCOS used to be a “vaporware” technology, which was only talked ab
