Key benefits of the Optoma ZK521ST at a glance:

• Dedicated golf picture mode: Enjoy a realistic display of your golf simulation with colour profiles optimised for greens and blues.

Brilliant picture quality thanks to 4K resolution and laser technology

Experience a picture quality that presents your presentations and simulations with exceptional sharpness. True 4K UHD resolution projects 8.3 million pixels onto your screen, delivering four times more detail than conventional Full HD. This high pixel density, combined with HDR and HLG compatibility, ensures precise rendering of textures and a realistic sense of depth. The powerful laser light source of the Optoma ZK521ST achieves a remarkable brightness of 5,100 lumens, so your content remains clear and high in contrast even in bright rooms without direct sunlight. Whether you are viewing detailed spreadsheets in a meeting room or vivid landscapes in your golf simulation, the faithful rendering supports you in every project. Enjoy a visual result that impresses with sharpness and colour accuracy.

Maximum flexibility for complex room situations

Discover versatile installation options for almost any room concept. The integrated short-throw lens lets you place the projector less than half a metre from the projection surface and still create large images. This prevents distracting shadows from people in the light beam. Set-up is made considerably easier by horizontal and vertical keystone correction and Four Corner Adjustment, so you get a precisely aligned image even on uneven walls or at unusual angles. For particularly demanding projects, the unit also supports 360-degree projection along the horizontal axis and portrait operation. This combination of optical properties and geometry correction gives you the freedom to align the projector exactly to suit your room.

Smart control and specialised application modes

Benefit from intelligent management and features tailored specifically to your projects. With the Optoma Management Suite, you can manage and monitor the projector conveniently and remotely. IT staff can view the unit's status in real time and create central operating schedules. Alternatively, you can control the projector directly from your smartphone via the Optoma Smart Control app and adjust picture settings without an additional computer. For virtual golf enthusiasts, the Optoma ZK521ST offers a picture mode developed in collaboration with GSPro. This mode reproduces the specific colours of virtual golf courses faithfully and delivers excellent contrast even with the room lights on. Thanks to seamless integration into existing networks via LAN, RS232 and AMX compatibility, the projector fits perfectly into professional control systems.
