The LG AU810PB Laser TV has a rated brightness of 2,700 ANSI lumens. So, how close did the AU810PB come to hitting its target of 2,700 ANSI lumens? I set the projector to BRIGHTEST Mode, which is the brightest picture mode available, and then I set the ENERGY SAVINGS to Minimum (brightest lamp setting). I then took 3-4 readings about 15-20% out from the center of the screen.
LG AU810PB Brightness (Vivid Mode, Maximum Light Level): 2,683 lumens
The AU810PB was close to its brightness claim. The projector's more accurate picture modes did reduce the projector light output but there was still more than enough brightness for viewing both SDR and HDR content on a 100" screen in a room with some ambient light.
Brightness by SDR Picture Mode
As mentioned, BRIGHTEST and VIVID modes are the least accurate and should only be used as a last resort to overcome a significant amount of ambient light. The EXPERT (BRIGHT ROOM) mode delivered the best balance of brightness and color accuracy. The FILMMAKER and EXPERT (DARK ROOM) modes were the most accurate picture modes out of the box. They are noticeable dimmer, but they still produced enough brightness to deliver a quality SDR or HDR image in a dark room.
While several picture modes delivered a good picture right out of the box, the AU810PB would benefit from calibration like any other projector. What is cool is that the AU810PB's Auto-Calibration feature let can quickly fine-tune using the Calman software with the press of a button.
While l I have experimented with Calman Auto Calibration on LG and Sony flat-panel televisions, this is the first time I had the opportunity to try out this feature on a projector. I set up my Klein K10 meter, plugged in my Murideo Seven G test pattern generator, and fired up my Calman software. Once the software identified the meter, pattern generator, and projector, I answered a few questions and pressed a button.
As you can from the image below, the results were outstanding. To test the projector's color accuracy we use Portrait Displays Calman color calibration software. The results before and after calibration are below.
Pre-calibration, the EXPERT (DARK ROOM) mode was pretty accurate, but there was too much blue energy. The Autocal feature took less than 2 minutes to produce excellent results with a delta error average below 1. It would have taken me 30 minutes to an hour to achieve the same results manually.
To utilize Calman AutoCal, you need some costly equipment and software, so this feature focuses on professionals because it speeds up the calibration process. However, it reinforces that AU810PB has one of the most advanced video processors available in a modern projector.
