Our Verdict
BenQ TH671ST
Epson EX3280
The Epson EX3280 and BenQ HT2050A are different projectors, each with strengths and weaknesses. The EX3280 is the brighter projector, as it is bright enough even for well-lit rooms. Inversely, the BenQ TH671ST has better contrast, so it looks its best when the lights are off. Ultimately, the BenQ is the better product for content consumption as it projects a 1080p image with a 16:9 aspect ratio, while the Epson's 1024 x 768 4:3 resolution is not well suited for watching movies and is better used as an office machine.
