The BenQ HT2150ST is low-profile (4.79-inch tall) and could be placed in various locations (a cabinet, tabletop, mounted on the ceiling, etc.). The projector is rather wide, its length is almost 15 inches and depth is 10.91 inches. However, it weighs 7.93 lbs, which is comparable with larger models. The front panel has a different color than the body and is smooth. The large lens window is rimmed with a red line and is located slightly off-center. On the left, there’s a small vent grill complemented with the whole mesh-grilled side panel. The arrow controls circle on top of the HT2150ST is also red-rimmed and well visible on the projector. The dials for focus and zoom tweaking are hidden behind the sliding cover.
The projector is based on the DLP technology and has a standard lamp providing from 3,500 to 7,000 hours of operation depending on the chosen mode. The lamp is bright, with 2,200 lumens but cannot ensure the saturated image in the daylight conditions. The BenQ HT2150ST projector supports the 2-million pixel resolution and brings a balanced and detailed picture in Full HD and 3D formats. It has the enhanced 6x RGBRGB wheel and covers over 96% or the Rec.709 color gamut. The display size varies from 60 inches at the shortest throw (1.8ft) to a 180-inch screen at 9.8ft. The picture can be zoomed 1.2x. The device supports vertical keystone regulation within 20 degrees ensuring the square image at any position.
The image detail and contrast are very high, with bright colors and dynamic transitions. The projector supports several picture modes that correspond with the different level of the ambient light and the performed tasks. The brightest Cinema mode features vivid colors and deep blacks and accurate grays and whites. The BenQ HT2150ST 1080p projector handles the dynamic motion well; the frames exchange each other smoothly, without judder and other noise. The projector has two gaming modes dedicated to the different conditions of the environment light. The general Game mode preserves the bright peaks and deep contrast and is used in the dark room. The Bright game mode keeps the colors and contours sharp in the semi-lit environment.
