Our Verdict

BenQ TH671ST

BenQ HT2050A

The BenQ HT2050A offers better image quality than the older BenQ TH671ST. Unfortunately, this comes at a cost, as the HT2050A has inadequate color accuracy out of the box, while the TH671ST excels in that area. If you're willing to calibrate it, then the HT2050A projects a brighter image, with better contrast, than the TH671ST.
