The high brightness and native 4K resolution, accurate color mapping, and contrast make the ViewSonic PX747-4K a worthy choice for the home theater setup. It doesn’t depend much on the environment light and has the enhanced zoom mechanism enabling several installation options in any room.

The body of the PX747-4K is rather bulky, with a 5.3-inch height, 13.1-inch width, and 10.3-inch depth. While its big size is somewhat compensated with the curved corners, the 8.84 lbs of weight prove it to be a stationary rather than a portable device. The projector has 3 feet, two of which are regulated to ensure optimal positioning.
The front panel is smooth with the large rimmed lens window revealing the significant zoom capability. The decorative plastic ribs next to the lens and the grilled speaker bring a unique design feature. On the top, there’s the zoom and focus dials, the large Power button, and navigation buttons. The remote is small but functional and has the backlight option for navigating in the dark.
The native 4K resolution embracing 8 million pixels makes the primary highlight of the ViewSonic PX747-4K review.

The high brightness of the lamp lets the projector produce a vivid and contrast picture in both dark and semi-lit environment. In the daylight, the detail gets somewhat reduced, while the overall color saturation doesn’t change significantly.
The blacks and grays have good uniformity and become even deeper in the HDR-compatible playback. The peaks are bright and the colors look saturated and natural, with especially true reds and greens. Whites are immense and non-transparent. The color mapping is very precise.
