In use on a projector product is simple with no adjustments. The result is an image with incredible sharpness, beautiful textures, sustained contrast, an image of a beautiful definition. The various plans are separate, with a picture "almost 3D." A product that does an exceptional job for a low price compared to more expensive products ...... The USB power requires special attention to get the best of this product. On a video projector, buy a special USB power for audio / video demanding digital device. Try it and adopt it ....... Having tried the Darbee 5000, I much prefer the HDELITE which seems to produce a less digital image. By against the Darbee can be configured in various ways contrary to HDELITE.
