The technology now used in InFocus DLP projectors has come a long way. It used to be common to switch on a DLP projector for the first time and immediately notice that certain colors just weren't right. The problem colors were yellow and red. Yellow would become a sort of a mustard color and red tended to shift towards orange. These issues were primarily only visible when presenting primary colors and when you were in certain color modes for PowerPoint presentation. Showing video from a DVD or VCR seemed to not cause these issues even if some of the scenes show strong primary colors. With the advancements, InFocus DLP projectors and a lot of other manufacturers of DLP projector have all but eliminated this problem.
