True 4K UHD business projector

The ViewSonic PX749-4K is a DLP projector delivering 3840 x 2160 native resolution with 4000 ANSI Lumens brightness and 12000:1 static contrast. It suits offices and classrooms needing large, vivid images on screens from 30 to 300 inches.

Check power, throw distance and signal sources

Verify the 100-240 VAC supply matches your mains and that the 0.75m to 9.76m throw range fits the room layout. Confirm your source devices can output 3840x2160 at 60Hz or 1440p at 120Hz to use the 4.2ms input lag and 240Hz refresh capabilities.

Questions about this item

What comes in the box with the ViewSonic PX749-4K and what must be purchased separately?

The box contains the projector, a power cable, a remote control and a Quick Start Guide. Ceiling mounts, HDMI cables or additional streaming devices are not included and must be bought separately if required.

Which resolution and refresh-rate combination should I choose for Xbox gaming on the PX749-4K?

For Xbox the projector supports a native 1440p resolution at 120 Hz with a 4.2 ms input lag, while other sources can use the full 3840 x 2160 resolution at up to 240 Hz.

How bright will a 300-inch image be with the 4000 ANSI lumens rating in a typical living room?

The 4000 ANSI lumens output is designed to keep a 300-inch 16:9 picture clearly visible even with some ambient light, and the 1.13-1.47 throw ratio lets you position the projector between 0.75 m and 9.76 m from the screen.
