ViewSonic PX747-4K review & specs

ViewSonic PX747-4K — True UHD Projector with HDR Support and Long Lamp Life

ViewSonic PX747-4K

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 projector has the versatile HDMI connectivity making it compatible with the Full HD content as well. It can produce a large display without losing in quality and not requiring too much space between the screen. The lamp life is standard but can be increased almost three times due to the integrated Super Eco mode.

Design

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.

Features

The native 4K resolution embracing 8 million pixels makes the primary highlight of the ViewSonic PX747-4K review. This DLP projector supports the wide color gamut with the RGBRGB wheel enabling 1-billion palette of hues; and has the contrast ratio of 12,000:1. It’s compatible with the HDR content but doesn’t support a 3D projection format.

The lamp in this projector is able to produce 3,500 lumens and can serve up to 15,000 hours, usage-wise. The projection distance varies from 3.2 to 38ft enabling the large screen of 300 inches. The zoom is 1.2x, complemented with the vertical keystone regulation within 40%.

The HDMI ports are represented by the 1.4a and 2.0 versions protected with the relevant HDCP protocols. Other connections include the VGA, mini audio jack, service USB, and mini-USB ports, 12V trigger. The mono speakers are rated at 10W in the ViewSonic PX747-4K manual.

Performance

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.

The ViewSonic PX747-4K 4K projector is quick and easy to set up with any video source or streaming dongle. The device has a good response and can be used as a PC monitor or a gaming display. The dynamic scenes might have a slight trail while the motion, in general, is pictured sharply, with the contours in place.

The integrated speaker is loud enough for a small room but doesn’t suffice for larger spaces. The sound quality is average, with somewhat thin bass but good voice clarity.
