Cinema SuperColor™ Technology
ViewSonic’s exclusive Cinema SuperColor™ Technology is able to meet 100% Rec.709 color gamut for producing the jaw-dropping, cinematic color you would expect at a movie theater.
USB Type-C for Direct Streaming and Recharging
The projector’s USB Type-C* connection puts a fun twist on streaming videos by allowing you to project content directly from your phone, laptop or tablet while also charging them simultaneously. You can even play Nintendo® Switch games on the big screen via direct connection without the dock.

Effortless Image Adjustment
Be it on the side table in the living room, bedroom or any other location you like, the projector can provide perfectly shaped images from any angle with comprehensive H/V keystone and 4 corner adjustment capabilities. The auto V keystone further frees you from manual adjustments no matter how you tilt the projector, up or down.

Adaptable to Any Environment
Equipped with a 1.3x optical zoom lens, the projector empowers users to choose the most ideal set-up location that doesn’t interfere with existing interior design while still getting the desired image size.
1.3x Optical Zoom
Perfect Projection, Even on Curved Surfaces
Who says projection only works on a flat surface? With our advanced Projector Warping Tool, the distorted image can be perfectly shaped through multiple point adjustments, even when projected on spherical or cylindrical shapes.
Go Big, Even in Small Spaces
Scale up the excitement with a screen size easily made larger than a TV, even in limited space. Immerse yourself in 100” of entertainment from only 2.5 m away.
1.13-1.47 Throw Ratio
Simplify Your Home with Unified Smart Systems
The PX728-4K comes with LAN control capability that is compatible with a variety of home automation systems (incl. Control 4, Crestron, AMX, PJ Link, and Network Control), making it a perfect addition to your smart home.
Get Your Cinema All Set at Once
With 12V trigger output connectivity, just power on the PX728-4K and your home cinema will be all set, with the curtains closed and the projection screen lowered automatically.
ISF Certified Color Calibration Tools
ISF (Imaging Science Foundation) certified Day and Night Modes deliver optimized color in both bright and dark environments. If needed, ISF-certified technicians can provide on-site tuning of these settings for customized image calibration that best fits your home.
Customize Your Own Color Profiles
By using a cloud-based color profile exchange, users can create their own color profile to fit their preferences and share it with others. Also, users can download other profiles from their projectors and fine-tune them as their own.
A Simpler Way to Update Projector Software
ViewSonic Projector Software Update is available online and enables you to keep your projector firmware up to date easily and conveniently with your laptop and USB cable connection; no need to take your projector into a service center for software updates.
Reliable Long-Term Lifespan
The latest SuperEco+ mode technology greatly extends the lamp life of the projector from 15,000 hours to 20,000 hours – meaning 4 hours a day for more than 13 years – saving you maintenance cost and effort.
USB Type-A Power Supply for HDMI Wireless Dongles
A built-in USB power output (5V/1.5A) can be used to supply power to HDMI wireless dongles, like Chromecast, Amazon Fire TV Stick, etc., eliminating the need for separate power adapters when streaming your favorite multimedia content.
Satisfying Audio Performance
The projector is embedded with a 10W speaker to deliver a satisfying audio performance right out of the box.
10W Speaker
A More Eye-Friendly Viewing Experience
Utilizing reflective light, which bounces off the wall or projector screen before hitting your eyes, the projector makes the viewing experience virtually blue light free, less invasive to your sight, and reduces eyestrain over prolonged viewing periods.
