Impressive visual clarity thanks to 4K UHD and laser technology
Experience a picture quality that presents your presentations and visual content with the utmost precision. The Optoma ZK451 uses an advanced laser light source to project vivid, authentic colours. Combined with a high brightness of 4,500 lumens, it creates clear, luminous images in almost any environment. Your spreadsheets and text documents remain perfectly legible even in brightly lit conference rooms. True 4K UHD resolution with 8.3 million pixels delivers enormous depth of detail, so your colleagues and business partners can effortlessly make out even the finest lines in complex graphics. In addition, HDR and HLG compatibility ensures realistic contrast. Objects look tangible and gain pronounced visual depth. This combination of brightness and high pixel density solves the problem of hard-to-see content in important meetings. Always present your results in the best light and leave a lasting professional impression.

Maximum installation flexibility in any room
Benefit from straightforward set-up that adapts seamlessly to your architectural requirements. The Optoma ZK451 impresses with a remarkably compact housing and can be integrated discreetly into existing premises. An integrated zoom gives you the freedom to choose the distance to the projection surface flexibly. Even in difficult room conditions, you can align the image precisely using horizontal keystone correction and four-corner adjustment, so uneven walls or awkward projection angles are no longer an obstacle. For special requirements in business or exhibition settings, the model also supports full 360-degree projection. This lets you realise unusual visual concepts such as floor projection without compromising image stability. An integrated speaker provides matching sound for short video clips in meetings. Save yourself costly alterations and use a projection solution that adapts perfectly to your room.
Intelligent control and reliable continuous operation
Rely on AV technology that works smoothly every day and can be managed centrally. With the dedicated management software, your IT staff always keep track of all projectors connected to the network. They can monitor device status in real time and schedule operating times conveniently from a distance. For direct operation in the room, the smart control app offers a practical alternative to the classic remote control, letting you control basic functions such as volume or picture mode directly from your smartphone. For demanding scenarios such as control rooms or digital signage, this projector is designed for continuous round-the-clock operation. High-quality DuraCore technology enables a lifetime of up to 30,000 hours for the laser light source. To put the unit into standby when not in use, an automatic function switches the projector off after a defined time. Enjoy the certainty that your equipment is always ready for use and integrates comfortably into your IT structure.
