The LG GRU510N is an HDR-compatible DLP home theater laser projector that retails for $3999. It utilizes a single DLP (0.47” DMD) chip to reproduce 4K UHD resolution (3,840 x 2,160). The unit's laser phosphor light engine can deliver 5,000 ANSI lumens of light output and has a rated life of 20,000 hours in Standard (high power) mode.
The GRU510N is part of LG's ProBeam series of projectors, which were initially developed for professional applications. The GRU510N is nearly identical to the LG BU50NST business projector we reviewed earlier this year. The only difference between the two units is the model number, and the BU50NST has a longer 3-year warranty.
These models' high brightness, 4K resolution, and good color reproduction are a viable option for an office or a home.
