BenQ SU931 Large Venue Projector Review -- Summary: Overall Impressions, Pros and Cons

Providing the most brightness for the dollar for mid-sized rooms, BenQ’s SU931 tops out at 6,090 lumens, has a wide 1.6X zoom lens and shows full 1,920 by 1,200 WUXGA resolution. It delivers surprisingly accurate audio and the projector’s images have excellent focus uniformity across the screen. While it includes all the ports you’re likely to need, the SU931 doesn’t have WiFi available for wireless data or let you display items on a network or USB thumb drive.


With it selling for about $2,900, the SU931 is among the cheapest projectors in its class. On the other hand, it’s operating expenses are on the high side. It is a steal, nonetheless, that can light up any conference room or small auditorium.
