Below are images of a variety of videos and photos in 4K and HD resolution. Like all our photos, they remain unadjusted for color, so they do not look as good as what the projector produced. All the HD and 4K images were taken with the HU85LS set to either EXPERT (DARK ROOM) and EXPERT (BRIGHT ROOM) mode.
Since most TV shows and live broadcasts will continue to be produced in HD for several more years, so good 4K upscaling will continue to be important. The projector's upscaling is excellent. Whether I was watching 720P sports from ESPN or 1080p Blu-ray content, it all looked very good. Most 4K movies do not have enough fine detail to make the difference between watching 4K SDR and HD noticeable.
While most Blu-ray UHD content is available in HDR10, a lot of 4K streaming material is still only 4K SDR. The HU85LS had no problems delivering sharp detailed 4K imagery.
Since a 4K DLP chip does not actually have 8.3 million mirrors, the HU85LS utilizes pixel (mirror) shifting to deliver the perceived sharpness of 4K resolution. This approach works very well. It is very difficult to see a difference in sharpness when comparing a 4K DLP projector like the HU85LS to a native 4K LCD/LCoS model from a normal viewing distance. Out of the box the 4K picture was good and after calibration the picture would be even better.
I would classify the overall picture quality of the LG HU85LS Laser TV as very good especially for a projector targeted at business and education applications. It delivered an image that would satisfy most of the folks considering it for a conference room, hotel lobby, or museum.
