Is the AK800ST a true 4K projector?

Yes. It has a native 3840 x 2160 resolution, so it shows 4K content without pixel shifting.

How close can it sit to the screen?

Its short-throw lens is designed to fill a large screen from a short distance, so it can sit near the wall instead of across the room.

Is 5,000 lumens enough for a lit room?

Yes. That output is high for a 4K projector and keeps the image usable with some room light, though direct sunlight still washes it out.

Does it have built-in speakers?

It has a small built-in speaker for basic sound, but most rooms will want external speakers or a soundbar for presentations and video.

Can I move it between rooms?

It is heavy and has a fixed short-throw lens, so it is better suited to a permanent ceiling or wall mount than to carrying around.

The projector comes with a power cable and a remote control; cables and a mount are usually bought separately.

About the BenQ AK800ST

The BenQ AK800ST is a 5,000-lumen 4K short-throw laser golf projector built for real rooms — its 0.69–0.83 throw ratio fills a full impact screen from less depth than most 4K projectors need. HDMI 2.1, ultra-low input lag, and Golf Mode 2.0 make it a simulator by day and a cinema or gaming screen by night. $3,999.

Short Throw for Tight Rooms

0.69–0.83 Throw Ratio

The AK800ST's 0.69–0.83 throw ratio and 1.2x motorized zoom let it fill a full screen from less distance than most 4K projectors — ideal when depth is tight or you want the projector mounted closer to the screen. Auto Screen Fit 2.0 and one-touch autofocus dial it in fast.
