digital signage applications. Allowing for presentations to transition from external sources seamlessly, the KHZ433UST’s PC-Free USB Media Player supports playback of video and audio files along with images and presentations shared directly from any USB device. Featuring a powerful 10-watt speaker, the KHZ433UST enhances presentations, videos and audio files by delivering crisp, robust audio. In addition, streaming and presenting
is made easy with an MHL-powered HDMI port that supports popular dongles including Optoma’s HDCast Pro and Amazon’s FireTV. The USB port can also be used to power Optoma’s WHD200 Wireless HDMI system or Google’s Chromecast media dongle.


Industry leading lifetime is achieved using Optoma’s DuraCore technology. Implementing advanced laser diode cooling techniques and an innovative dust resistant design. 20,000 hours provides a staggering 13 years of normal use*1 or 2.2 years if run continuously 24/7.

*16 hours per day, 250 days per year

Dust resistant optical engine

The KHZ433UST has been independently tested and certified with an IP5X dust resistance rating. Outstanding resistance to dust in combination with exceptional brightness ensures industry leading durability; paramount for 24/7 maintenance free operation in challenging environments; the dust resistance was tested by an independent laboratory in accordance with IEC standard 60529 and was certified with an IP5X rating. The dust resistant filter-free design prevents dust and dirt from affecting the system, ensuring optimal image quality with minimal maintenance.

Ultra short throw lens

High quality UST lens delivers large images from a short projection distance. Presenter dazzle and image shadows are avoided.

Bright, detailed rich in color images

The Optoma KHZ433UST provides 4500 lumen brightness ,and 200,000:1 contrast ratio to produce bright visuals and razor sharp text. Superb color accuracy and powerful color performance is achieved because of the wide coverage of Rec. 709 color gamut typically associated with DLP® technology.

This projector's native resolution is 1080p (1920x1080), but  also compatible for maximum WUXGA resolution (1920x1200).

Image quality

Image quality is of paramount importance for every installation product. The KHZ433UST delivers deep rich and colorful images whilst maintaining an exceptional high level of consistent brightness that will captivate and engage any audience.

The Optoma KHZ433UST uses DLP® technology for its image quality and unmatched reliability. The reflective nature of DLP® micro-mirror technology provides highly efficient bright images with great contrast whilst maintaining precise color accuracy and natural, real-world color reproduction. For demanding professional applications, the proven reliability of DLP® technology makes it the obvious choice.

Total cost of ownership

The total cost of ownership of a projector is not in the purchase cost but in expensive maintenance and service. The Optoma KHZ433UST requires very little maintenance; have no user serviceable parts inside and no filters that require periodic replacement. The result is low cost, predictable service cycles, enabling planned down time to be minimized.

Versatile Installation

Images can be projected in portrait mode, where the projector is operated on its side, to produce a tall, thin image. This is perfect for digital signage applications, particularly in retail premises.

PC-Free USB Media Player

The KHZ433UST's USB port supports Multimedia Function that allows you to plus in your USB flash drive and access the photos, music, MS office files stored.

System integration and control

Multiple projectors can be monitored over the LAN and can also send an email alert via Crestron RoomView in the event of an error or a lamp failure. Projector status can be monitored via a web browser, while Extron IP Link, AMX Device Discovery and PJ-Link protocols offer remote management of most functions across a network, keeping you in control wherever you are.

Enlarge your images

The digital zoom feature can be used to increase the magnification of a particular area, allowing explanation of the projected image in more detail.

Perfect projection

Misaligned images can be quickly adjusted with vertical keystone correction.

Dual HDMI inputs

Project crystal clear images using either of the twin HDMI inputs. HDMI V1.4a is supported, including MHL on one of the inputs. Computer and HD video sources are supported, while separate audio cables are no longer required.

Audio capabilities

The powerful built in 10W loudspeaker can be used in conjunction with a microphone, to capture the attention of the audience. Expensive additional audio hardware and cabling can therefore be eliminated in smaller meeting rooms.

For larger installations, audio inputs from a computer or video source can also be handled, allowing the projector to act as an audio switcher and volume controller, alongside an external audio amplifier and speakers.

Projector security

The projector features a Kensington Lock slot to deter theft, while password protection prevents unauthorised use.

Installation Applications

Delivering outstanding reliability, high intensity brightness, stunning colors and spectacular image quality, the KHZ433UST series is precision engineered to power larger than life experiences. The Optoma KHZ433UST is the perfect solution for classrooms, meeting rooms and space limited projection projects, even digital signage, with or without interactivity requirement.

Museums, exhibitions and visitor centers

Eye-catching content and bright lifelike images guarantee to engage and capture the interest of an audience at any visitor or entertainment venue. The lightweight and dynamic KHZ433UST satisfies the requirements for a dependable signage solution. Supporting portrait mode, rear and downward projection, this UST projector offers complete flexibility for any professional installation.

Retail displays and digital signage

The ultra-high 100,000:1 contrast ratio ensures no detail is lost which is key for punchy corporate presentations, retail signage and projection mapping where every detail matters. The 4000 lumen light source delivers exceptional consistent brightness, rendering vibrant images, even in high levels of ambient light. Large images with a diagonal measurement of 100 inches (254cm) can be accomplished from a throw distance of just 31cm.


The DuraCore laser light engine replaces the traditional lamp based projector removing the need for replacement lamps, maintaining low running costs. Unlike lamp based projectors, the DuraCore laser supports instant power on/off. The efficiency of the laser helps the projector run more quietly with lower energy consumption and heat dissipation.


Industrial grade simulators for aircraft, track cars and commercial vehicles demand ultra-high resolution projectors capable of maintaining high consistent brightness levels. Simulators can now be implemented using fewer projectors, reducing overall complexity in terms of hardware. Thanks to the native 1920 x 1080 resolution, even complex, computer generated images can be displayed with remarkable clarity.

Control Rooms

High resolution and high contrast make this model suitable for installation in control rooms where fine lines and small text must demonstrate pixel perfect precision.

Engineering and Design

CAD environments, architecture and 3D modelling all require projected images with absolute clarity and accuracy. The projector is fully 3D compatible, and can be used in conjunction with active shutter glasses to generate convincing 3D visuals.
