Optoma projector ZK521ST

Eco-friendly compact 4K UHD laser projector with high brightness and short throw distance
The ZK521ST is one of the most compact and trouble-free 4K UHD DuraCore laser projectors from Optoma to date. With a brightness of 5100 lumens, designed for maintenance-free continuous operation, this projector delivers high image performance with flexible installation features and extensive connectivity options in an elegant, compact design that is up to 34% smaller than previous Optoma models.
In support of Optoma's commitment to sustainability, the ZK521ST reduces energy consumption by up to 45% compared to Optoma lamp projectors. The energy-efficient DuraCore laser technology provides a long product life of up to 30,000 hours without the need for replacement lamps, requires minimal maintenance and contains no mercury, further reducing its carbon footprint.
Using the Optoma Management Suite (OMSC)™, you can easily manage this projector and other compatible devices remotely. This powerful cloud solution offers easy control, real-time monitoring and scheduling, which helps reduce downtime, streamline operations and lower operating costs.
This latest model is also compatible with the new Optoma Smart Control App for Android and iOS, so several functions can be managed without the need for a PC. Switch the device on and off, adjust the volume, change and set display modes, and make remote image corrections via your smartphone.
This projector is enhanced for golf simulation and features a specially designed throw ratio and tuned picture modes for golf simulators. To create an immersive and more realistic gaming experience, Optoma worked closely with colour experts from GSPro to develop a dedicated GSPro mode.
The ZK521ST is designed for conference rooms, meeting halls and other corporate spaces. It is equipped with a short-throw lens, meaning it can be placed less than half a metre from any wall. For maximum convenience, it features RJ45 and RS232 connections for monitoring and control, as well as a built-in speaker.
True 4K UHD resolution
Ultra HD 4K resolution delivers a sharper, more realistic image and richer colours, allowing you to sit closer to the screen and enjoy an immersive experience.
Optoma DLP projectors provide true 4K UHD resolution approved by the CTA (Consumer Technology Association), which can project 8.3 million pixels onto the screen. This means four times more detail than Full HD and twice as much as competing technology that provides only 4.1 million pixels.
Viewing with the lights on
This versatile projector combines high brightness and vivid colours for a brilliant, realistic image in any environment. Make a lasting impression with larger and more striking presentations at any time of day.
HDR and HLG compatible
Capable of receiving and displaying HDR content in both HDR10 and Hybrid Log Gamma (HLG) formats. This Optoma projector lets you see far more detail and texture. Objects look more solid and realistic, and the added detail creates a greater sense of depth.
Connect anytime, anywhere
Businesses can rely on their IT managers to provide remote support using the Optoma Management Suite (OMS)™. IT managers can easily monitor and diagnose issues with any Optoma AV display, ensuring that staff are never left without help. For an even higher level of readiness, companies can also set up alerts and broadcast emergency notifications.
Golf Sim picture mode
The Golf Sim picture mode delivers realistic shades of green and blue and impressive detail, even with the lights on. It has been carefully created to provide optimal colour gradation for golf simulator setups.
Designed for the future
We are committed to reducing the overall environmental footprint of our products, so that we act responsibly towards our planet.
Designing innovative products with sustainability in mind takes into account every stage of the product lifecycle, from design, manufacturing, packaging and logistics through to use.
Four-corner correction
Four-corner correction allows you to adjust the keystone distortion of the projector in both vertical and horizontal planes, so you can individually adjust each corner of the projected image to make it perfectly rectangular. Ideal for uneven walls or spaces where projector placement is complicated or restricted and installation at an angle is necessary.
Laser technology
Optoma laser projectors use high-quality lasers to create the projected image. In many situations, the perceived brightness of laser-illuminated projectors can be twice that of an equivalent lamp model. They also provide higher efficiency to maintain consistent brightness, top-tier colour performance, instant on/off and an exceptional lifespan of up to 30,000 hours.
DuraCore
Industry-leading lifespans are achieved with Optoma's DuraCore technology. It uses advanced laser diode cooling techniques and an innovative dust-resistant design.
Short throw distance
With the short-throw lens you can project an impressive 100" image from a distance of just over one metre. This allows you to place the projector closer to the wall, which reduces shadows, so you can present without problems.
Control
Thanks to a wide range of options, you can control and monitor the projector remotely.
• RS232 Optoma projectors come with an extensive set of RS232 commands, making them simple and easy to manage with any control system.
• AMX compatible The Dynamic Discovery protocol is integrated into the projector, enabling easy installation with AMX control systems.
• Crestron RoomView Using compatible RoomView software, you can switch up to 250 projectors on/off, monitor, manage and control them simultaneously from any computer.
• Extron IPLink compatible Enables easy installation with Extron control systems.
