The ZH420UST is powered by a long-lasting, low maintenance DuraCore laser light source. The lamp-less design vastly reduces running costs for a low total cost of ownership.

Weighing only 5.5kg, this projector can be mounted just centimetres away from a wall or surface and can project an image size of over 100 inches (254cm).

Supporting 24/7 operation and versatile orientation, the ZH420UST is a flexible, powerful and bright ultra short throw projector which makes for a superb signage solution where space or accessibility can be limited, such as shop windows, museums or retail displays.

Advanced features of this model include integrated HDBaseT receiver, and warping and blending engine (multi-output graphics card supporting overlap adjustment is required).


Industry leading lifetime is achieved using Optoma’s DuraCore technology. Implementing advanced laser diode cooling techniques and an innovative dust resistant design.

IP5X Dust resistant optical engine

IP5X Dust resistant optical engine

Independently tested and certified to IEC standard 60529 with an IP5X dust resistance rating. Outstanding dust resistance combined with exceptional brightness ensures industry leading durability; paramount for 24/7 maintenance free operation in challenging environments.

Ultra Short Throw

With an ultra-short throw lens, you can project an impressive image greater than 100” from less than a metre away. This allows you to place the projector closer to the wall, reducing shadows so you can present with ease; perfect for interactive applications.



Uncompromising, uncompressed Full HD video, audio, network and control commands all delivered on a single CAT- type cable capable up to 100 metres/328 feet without signal loss makes installation hassle-free. HDBaseT™ simplifies cabling requirements and reduces installation complexity saving both time and reducing costs.

Integrated warping and edge blending processor

Integrated warping and edge blending processor enables multiple projectors to be warped and blended without additional dedicated hardware, reducing the cost & complexity of installation. Warping and edge blending is configured using either the projectors on screen display or with PC software depending on model.

*Compatible multi output graphics card with overlap function is required.
