How much does the BenQ TH671ST cost?

The TH671ST currently lists at $920.35 to $949 on Shopfox — flagship-projector money for a 1080p unit, justified by the short-throw lens and gaming-tuned latency. Weigh it against 4K alternatives at similar pricing before buying, and check the BenQ TH671ST's price history on Shopfox for dips.

Does the BenQ TH671ST support 4K input?

It accepts 4K signals and downscales to its native 1080p panels — standard practice for this class. The TH671ST's sharpness at 1080p is its real strength at gaming distances. Buyers wanting native 4K pixels should step up to BenQ's 4K models; for 100-inch gaming, the TH671ST's 1080p looks crisp.

How close to the wall can the BenQ TH671ST sit?

Very close — its short-throw lens casts a 100-inch diagonal picture from roughly five feet, so the TH671ST suits rooms where a standard projector would need double the distance. That placement flexibility, avoiding shadows from players walking past, is why the BenQ TH671ST is popular in apartments and game rooms.

Great projector

Great projector for gaming! I have a blast with it. Just make sure you find the right distance before mounting, because you can zoom in but not out.
