High-brightness short-throw 4K UHD laser projector

The Optoma ZK608TST delivers a native 3840 x 2160 resolution at 6000 lumens, using a DLP laser light source rated for up to 30000 hours. Its short-throw lens produces a 30 to 300 inch image from a close distance, while manual horizontal and vertical lens shift simplifies alignment. Built-in dual 15W speakers provide audio without external hardware.

Sustained 24/7 operation with IP6X optical engine

An independent IP6X certified optical engine protects the light path from dust ingress, enabling continuous 24/7 running without filter maintenance. The laser source maintains consistent brightness over its 30000-hour lifespan, avoiding the output decay typical of lamp-based models. A 2500000:1 contrast ratio and HDR compatibility preserve image depth during extended sessions.

Eco chassis with HDBaseT 3.0 and LAN control

The cabinet uses up to 50% post-consumer recycled plastics and packaging reaches 97% recyclable materials. Connectivity includes HDMI 2.0, D-Sub, HDBaseT 3.0 for uncompressed video over long cable runs, RJ45 for network management via OMS Local, RS232 and USB. Buyers needing ultra-short throw ratios or motorised lens shift will find those absent here.

Questions about this item

How loud does the 6000 lumen laser engine run during 24/7 operation?

The IP6X certified optical engine is sealed for dust resistance and designed for continuous 24/7 use without filter maintenance, keeping acoustic output stable over the 30,000 hour light-source life.

What source devices must I already have to send 4K HDR video to the HDMI 2.0 and HDBaseT 3.0 inputs?

Any player, PC or media streamer that outputs 3840 x 2160 at up to 140 Hz over HDMI 2.0 or HDBaseT 3.0 will drive the projector natively.

Will my existing D-Sub VGA laptop and analog RGB gear still work alongside the digital inputs?

Yes, the projector retains a D-Sub 15-pin port and analog RGB compatibility so legacy laptops and older AV equipment can share the same installation.
