REVIEWS


Best of Show Winner

““ViewSonic's PX748-4K is one of two new gaming projectors (along with the PX701-4K) that offer high brightness while hitting a new low for input lag: approximately 16 ms for 4K/60 Hz signals, 8 ms for 1080p/120 Hz, and as little as 4 ms for 1080p/240 Hz. We've seen similarly spec'd models emerge from other brands, but with a street price of just $999 the PX748-4K offers exceptional value. Besides its high 4,000-lumen brightness and low input lag, it’s fairly well-equipped for a budget projector, with extras that include a USB-C port for direct streaming from mobile devices; a 1.3x zoom and auto-keystone/warping for setup, and the ability to add a WiFi wireless dongle.””
