LG AU810PB 4K UST Business Projector Review – Summary: Highlights, Pros and Cons


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.

It offered accurate out-of-the-box color reproduction, and it is one of a few projectors with Dynamic HDR Tone mapping and HGiG. It is also one of the first projector equipped with the latest HDMI 2.1 features, including eARC and ALLM.

The AU810PB has horizontal/vertical lens shift and 12-point geometry correction combined to provide exceptional installation flexibility.

Hot Product Award Badge

Since the AU810PB was built around the WebOS operating system, which is used in many of LG's flat-panel TVs, Smart features are incorporated seamlessly, and the menus are easy to navigate and well laid out. The AU810PB is loaded with many of the most popular streaming apps including Disney+, YouTube, and Fandango Now. 

Since the AU810PB was designed to replace a flat panel TV, it has all the Smart features customers expect from a Smart TV. You can use the Smart remote for voice control with its built-in microphone to control basic projector features and control a wide variety of compatible Smart devices via Google Assistant and Amazon Alexa.

The AU810PB is also the first projector I have reviewed that is WiSA compatible so that it can broadcast sound to multiple wireless speakers. This eliminates the wires and the A/V receiver, so it is easier for anyone to set up a stereo or a full surround system.

The AU810PB delivered a great picture and is packed with firsts, which is why we are awarding it with a Projector Reviews Hot Product Award.


The AU810PB and its little brother, the HU810PW, are the first projectors equipped with HDMI 2.1 features like eARC and ALLM. No other projector in the AU810PB or HU810PW price points includes all the advanced features found on these models.

While Most laser DLP projectors below use a blue laser light source with a phosphor wheel.  LG AU810PB utilizes the multi-channel laser system found in LG's higher-priced award-winning ultra-short-throw model, the HU85LS.

They are the first projectors I reviewed that support multi-channel wireless speakers via WiSA or HGiG, which enhances HDR gaming. When you consider both projectors also include vertical/horizontal lens shift and an adjustable iris, it is easy to see why these two models are in a class by themselves.

The AU810PB is black, and it is designed for the custom installation market. The HU810PW comes in white and will be able to consumers directly from LG. Since the LG HU810PW utilizes a lot of the same hardware, it delivers the same picture quality as the AU810PB for about $1000 less.

However, it lacks many notable features found on the AU80PB, including a 12v Trigger, WiSA, Auto Calibration (via Calman), and a 2-year warranty. The LGAU810PB is by far the most advanced and feature-packed model; on the market below $5000.
