Both models combine an 8,500-lumen DuraCore laser light source with DLP projection technology to produce bright, detailed images at a native resolution of 3840 × 2160.\u003c\/p\u003e\n\n\u003cp\u003eThe two projectors share the same core imaging platform but use different fixed lenses. The ZK810T features a versatile standard-throw lens with a 1.26–2.00:1 throw ratio and 1.6× motorised zoom. The ZK810TST uses a 0.65–0.75:1 short-throw lens with 1.15× motorised zoom, allowing a large image to be produced where the available distance between the projector and screen is limited.\u003c\/p\u003e\n\n\u003cp\u003eInstallation is supported by motorised zoom, focus and horizontal and vertical lens shift, making it easier to align the image without physically repositioning the projector. Keystone adjustment, four-corner correction, 360-degree installation and portrait operation provide additional flexibility for conventional screens, digital signage, projection mapping and creative immersive applications.\u003c\/p\u003e\n\n\u003cp\u003eOptoma’s DuraCore laser system provides up to 30,000 hours of operation, while the independently tested IP5X-rated optical engine helps protect internal components from dust. Both models are suitable for continuous 24\/7 use and include HDMI, HDMI output, HDBaseT, LAN, RS-232 and 12V trigger connectivity for integration into professionally controlled AV systems.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e8,500-lumen output produces bright, clearly visible images in professional installation
