Is the BenQ TH671ST good for gaming?

Yes. It has low input lag and a fast DLP response, which keeps fast action smooth. It is one of the main reasons people buy it.

How big a screen can it throw from close up?

The 0.69 to 0.83:1 throw ratio lets it fill a large screen from a short distance, so it works in small rooms. Exact size depends on placement and zoom.

Does it support HDR or 4K?

No. It is native 1080p with no HDR support. It accepts 1080p and lower formats only.

How long does the lamp last?

BenQ rates the lamp at about 4,000 hours at full brightness and up to 10,000 to 15,000 hours in eco mode. Actual life depends on settings and use.

Do I need external speakers?

The built-in 5 W speaker is fine for casual use, but most owners add a soundbar or speakers for movies and games.

Can I place it off-center?

It has vertical lens shift and keystone correction, but no horizontal shift. Off-center placement relies on keystone, which can soften the image.
