Hisense PX4 Pro UST Laser Projector Review: Bright Visuals Hindered by Software Quirks
Tom's Guide evaluated the Hisense PX4 Pro ultra-short-throw 4K laser projector, which retails for $4,499. Lab testing measured 3,612 ANSI lumens and strong color reproduction, alongside responsive gaming performance with VRR support and low input lag. However, the reviewer found that Vidaa OS suffers from intrusive ads and aggressive Scenario Enhancement processing that automatically engages with the optical iris, causing noticeable color flickering. Unless high-refresh gaming features are essential, buyers may find better overall value in previous-generation models or alternative UST competitors.
