Projector Reviews Comments

The BenQ TH690ST, BenQ may be a perfect fit for a consumer who wants to get into gaming with a projector for the immersive gaming experience only gaming on a projector can provide. Remember that the TH690ST provides a 100-inch image at only 4.9 feet from the projector screen which means you can enjoy an immersive experience even in a smaller room.

You get a short-throw projector that is HDR10 compatible that can deliver accurate colors for watching your favorite movies and TV shows. The dual integrated treVolo 5-watt chamber speakers also sound good for their small size.

I highly recommend the BenQ TH690ST 4LED Console Gaming Projector for anybody looking to get into gaming with a projector. As such, I easily decided to give the BenQ TH690ST Projector Reviews “Highly Recommended” award.
