Who wins on what

Ranked by what users actually praise

Overall Impression

Bright, sharp true 4K picture praised by many owners. Commenters describe a stunning image on screens up to 100-300 inches, watchable even with ambient light, a lamp on, or windows uncovered. Several say it looks brighter and more vivid than Epson's pixel-shifting 4K projectors, with true 4K DLP resolution rather than eShift. Gamers especially praise how vivid and 'electric' games look on a large wall projection, calling picture quality a major strength for the price.

Fan noise and humming are common complaints. Multiple users report a noticeable humming or buzzing noise, with at least one returning the unit specifically because of it, especially compared to quieter alternatives like the BenQ TK800. Others ask directly about fan loudness before buying, suggesting it's a known concern. One user says silent mode reduces noise but limits resolution to 1080p, undermining the 4K feature during quiet operation.

Contrast ratio and some reliability issues hold it back. Several commenters note the 12000:1 contrast ratio is far below rivals like the Optoma UHD60 (1,000,000:1) or UHD300x, resulting in weaker black levels praised less than color and sharpness. Some units reportedly develop faults: one green-flashes and randomly shuts off, another develops a color wheel defect tinting the whole screen green, and a companion PX748 model shows random white dots on black screens.
