I also experienced rainbows in some content during my time with the projector. Additionally, as the N1 is a DLP projector, it is also susceptible to rainbows, which is a trait commonly seen in single-chip DLP projectors. The speckle was visible at lower backlight levels as well but most noticeable at higher levels, particularly in red, yellow, or green content. It was most prominent when the projector backlight was set to anything over 8. While this may very well be successful at reducing speckle, it does not eliminate it completely as I unfortunately did experience some degree of laser speckle during my time reviewing the N1 Ultra. Laser speckle can be a somewhat common occurrence with multi-laser light engines, and according to JMGO's claim, their LSR technology reduces laser speckle by 96%. The last part of the light engine is what JMGO calls the Dynamic Light Speckle Reducer (LSR), which serves the purpose of changing the amplitude and frequency of the laser as it passes through to reduce laser speckle from the focused laser light. JMGO claims to achieve over 95% brightness uniformity with this method, a figure we were able to verify. The purpose of increasing the number of partitions to over 400, compared to the more common figure of just over 100 partitions, is to enhance brightness uniformity. This diffuser employs 400 miniature partitions on each layer, with each partition acting as a diffuser. The light engine also incorporates the Quad Layered Diffuser System, which converts the laser spot into a uniform 16:9 image. The NUMB12T laser provides a light source life of 30,000 hours. This co-developed 9-chip laser design offers advantages such as 10-15% higher efficiency, 40% reduction in size, 10% better heat dissipation, and approximately 30% lower cost compared to the more commonly used 14-chip and 28-chip lasers. The NUMB12T laser integrates multiple RGB lasers into one source, achieving modulation of laser output by varying the current to the laser. In collaboration with Nichia, a Japanese engineering company specializing in manufacturing and distributing phosphors, light-emitting diodes, and laser diodes, JMGO co-created the NUMB12T laser. JMGO's patented MALC technology focuses on providing higher levels of brightness, color, and overall efficiency. It employs JMGO's self-developed MALC (Microstructure Adaptive Laser Control) Triple Color Laser Optics engine to deliver a bright and vivid image. The JMGO N1 Ultra utilizes Texas Instruments' popular 0.47-inch 4K DMD DLP chipset, which starts with a native 1080p micromirror chip and then enhances the image with ultra-fast four-phase pixel shifting.
