BenQ LH820ST

If you’ve been waiting for BenQ to manufacture a golf simulator projector with a throw ratio under 0.5, you’re in luck! BenQ’s newest model, the LH820ST, will compete with the likes of the Optoma GT2000HDR (formerly GT1080HDR), GT1090HDR and ZH450ST (formerly ZH406ST).

Explore the features, setup, and specifications of this short-throw projector in this BenQ LH820ST projector review.

BenQ LH820ST Projector Features

With a throw ratio of just 0.497, horizontal and vertical keystone, trapezoid correction, and corner fitting for fine tuning, the BenQ LH820ST provides mounting flexibility unlike many other projectors while outputting a top notch 1080p high definition image.

Thanks to its high brightness output (3600 lumens) and contrast ratio (3,000,000:1), capability to be mounted in many different spots, and low latency <17ms (at 1080p/60Hz), the BenQ LH820ST is a great golf simulator projector that allows you to enjoy seamless dynamic visuals and lifelike experiences. The laser light source will help provide that great image for up to 30,000 hours. 

BenQ LH820ST Projector Setup

Due to its short throw ratio, golfers will likely want to mount this projector on the floor in front of their hitting area. That might sound dangerous with swinging clubs and flying golf balls around, but not when you’ve got a friend like Carl, who makes a protective enclosure just for that purpose. 

Once the LH820ST projector is installed, the projected image can be easily tweaked to the golfer’s liking by reducing and shifting it by 0.5%. This feature ensures that the final result is precisely how you want it to be.

The LH820ST projector is equipped with sealed laser modules and enclosed light engines that provide maximum protection for its optical components, including the DMD chip, color wheel sensor, and laser package. This innovative lock-and-key design ensures that the engine stays free from dust, which in turn extends the projector's lifespan.

The technology has also passed the rigorous dust chamber test standard, earning it an impressive international dustproof rating of IP5X.
