Both models feature the DLP matrix standing for good contrast and focus while yielding in term of brightness and color density to other projectors in the class. The key difference to choose BenQ HT2050 vs BenQ HT2150ST is in resolution handling, throw ratio. It’s also worth to compare the throw distance and speaker specs.
The projectors feature the same brightness and contrast specs, with the good amount of black; still, some white spots might be seen on particularly light-colored pictures. The BenQ HT2150ST vs HT2050 has shorter throw with the considerable throw ratio, making it a good choice for gaming. It also integrates quite decent 20W stereo speaker to support immersive gaming interface with the quality sound. In comparison, the BenQ HT2050 has longer projection distance and bigger input lag. Still, its large resolution (over 8 mln pixels) makes it a great device for movie-watching.
By inspecting BenQ HT2150ST vs BenQ HT2050 design, I can say that they look and weigh much the same, having the stylish compact box with rounded angles, and somewhat small and flat navigation buttons on the top. The BenQ HT2150ST versus the HT2050 is more versatile, as it can be mounted in the rear position. The BenQ HT2050 can throw the picture from the ceiling mount, front or tabletop as well. It can be adjusted vertically up to 40 degrees, enabling more options for its easy installation.
