The Acer K335 provides an attractive option for those looking for a reasonably priced, portable projector that has above average light output (i.e., for this class of pocket projector). It provides a sharp, fairly bright image for business presentations for screen size of up to perhaps 90 inches diagonal. It handles non-native resolutions quite well and displays fair color rendition in all but the brightest picture mode. The lack of a zoom lens causes initial setup to take more time, but that’s the trade off one must make for such a compact sized projector. The K335 needs to be placed a few inches lower than the bottom edge of the projected image. There is an adjustable front foot for tilting the front of the projector upward and when you do this the projector's automatic keystone correction will restore proper image geometry.
Mini LED-based projectors have steadily improved over the past few years and in some ways the Acer K335 benefits from that evolution. The K335 is very versatile, highly portable business projector with support for the most popular input options, offering a low price, long-life LED light source, good brightness and fair color reproduction. The Acer K335 should prove to be popular in the mini projector market.
While well suited to the needs of a business traveler/presenter, the Acer K335's shortcomings in terms of color accuracy, black level and contrast ratio make is less well suited for use in the home as a projector for TV and movie viewing.
