The LG AU810PB is a 4K DLP projector that retails for $3999. It utilizes a single DLP (0.47″ DMD) chip to reproduce a perceived 4K UHD resolution. Its multi-channel Laser-light engine is rated to deliver at 2,700 lumens for up to 20,000 hours, giving you several years of maintenance-free operation.

I’ve had the projector for almost two months now. Image quality is what I would expect from a 4K device. The image is bright and the contrast is great. Blacks are deep and it’s hard to tell you’re watching a projector (compared to a 4K TV).

I’ve had the AU810PB for a couple of weeks, replacing a BenQ HT5550 projector. The LG is noticeably much brighter. Image is sharp, HDR looks excellent, and projector supports eARC which is a plus.

The AU-810B is an awesome and versatile projector. The price point is also very good for the quality you get. Set up was simple, and the good thing is I can use it with lights on or off. I would recommend this product

I have now taking my projector back twice due to focus uniformity issues. When the projector works it looks great, but it seems to keep going out of focus every 20 minutes. Hopefully they can fix it a second time but if not I really want my money back.

I've had it set up and working for over a week now, and the difference between this and my old 1080p projector is very noticeable. Great image clarity and detail, bright with great contrast. I've used it with an Xbox Series X, playing games and videos via Amazon Prime, both at 4k.

I wanted to go with the HU810 first but it was unavailable so switched to AU810. Perfect picture for home theater. Crisp and clear! set up is super easy. after couple of week I switched to Expert Dark room mode and its "A"mazing! Setup was easy no brainer.

Unfortunately this DLP projector does not support 3D Blu Ray. Given the fact that single chip DLP projectors are capable of delivering 3D images that are in many ways superior to your local theater, LG decided to leave this feature off.
