Verdict

The ViewSonic PX747-4K is a high-brightness DLP projector delivering 4K Ultra HD resolution (3840x2160) via XPR pixel-shifting technology with support for HDR and Rec. 2020 content. It is specifically designed for environments with ambient light, such as living rooms, featuring a potent 3,500 ANSI lumens output, a 12,000:1 contrast ratio, and a lamp life reaching up to 15,000 hours in SuperEco mode. Main pros include its exceptional brightness for daytime viewing, a sharp 8.3-million-pixel image, and flexible connectivity with dual HDMI ports (one HDCP 2.2) and a 1.2x optical zoom. However, common cons include loud fan noise (approximately 27–33dB), weak black levels and contrast in dark rooms, and a 'light border' or halo effect around the projected image typical of its 0.47-inch DLP chip.
