The Optoma EP's 2x speed color wheel is perfectly acceptable for data presentations and still graphics, as people affected by color separation artifacts seem to be bothered by them less often when viewing stills. However, keep in mind that the EP's 2x speed color wheel may limit its usefulness as a full time home theater projector.

Video scaling results in a slight loss of image sharpness, so video detail is not quite as razor sharp as it would be on a comparable home theater projector. Deinterlacing is not comparable to home theater quality either; artifacts and jaggies appear in quite a few scenes that are displayed cleanly on home theater projectors.

However, both are good enough as to be acceptable for occasional home theater use. Keystone adjustment is an important feature for portable projectors and the EP handles it well. About this product. Make an offer:.
