Optoma ZK810T 8,500-Lumen 4K HDBaseT Laser Projector for Large Rooms and Continuous Operation

Optoma ZK810T – 4K installation projector for large rooms, continuous operation and professional AV integration

The Optoma ZK810T delivers 8,500 lumens from a maintenance-free laser unit and displays 4K UHD content via DLP XPR pixel shift – suitable for lecture halls, conference centres, museums and digital signage installations where reliable image performance and minimal maintenance are crucial. The projector is approved for 24/7 continuous operation, can be mounted in any orientation and integrates fully into professional room control systems via HDBaseT, LAN, RS-232, Crestron, AMX and Extron. Motorised lens shift (±55 % horizontal, ±25 % vertical) and a 1.6× optical zoom allow flexible positioning without digital keystone correction.

Applications: what the Optoma ZK810T is ideal for

Permanent installation and digital signage

The maintenance-free laser unit lasts up to 30,000 hours – more than 10 years without lamp replacement at 8 hours of daily operation. Approval for 24/7 operation and direct start via mains power make the ZK810T a reliable basis for digital signage installations, control centres and public information displays. Programmable on/off times (Scheduled On/Off) allow fully automatic operation without staff on site.

Lecture halls, conference centres and training rooms

8,500 lumens ensure an easily legible 4K image even in rooms with daylight that has not been blacked out. HDBaseT allows signal feed via a single Cat6a cable up to 70 m from the AV rack – without HDMI extenders or separate network cables. Network control via web interface, PJLink and the Crestron, AMX and Extron protocols allows central management and remote maintenance over the existing building network.

Flexible permanent installation in large rooms

The motorised lens shift allows flexible optical image positioning without keystone correction. The 1.6× optical zoom also lets you adjust the image size after commissioning without changing the mounting location. 4-corner correction and geometric warping are available for curved screens or irregular projection surfaces.

Picture and sound quality

The Optoma ZK810T uses DLP technology with a 0.65" DMD chip and XPR pixel shift: the chip shifts its pixels in rapid succession to achieve full 4K resolution with 8.3 million displayed pixels. In business use with ambient light, DLP technology offers high ANSI contrast – text slides, diagrams and CAD content appear sharp and clearly defined. The brightness of 8,500 lumens is designed for rooms up to lecture hall size; dynamic contrast is 3,000,000:1 and native contrast 1,100:1. HLG is supported as the HDR standard.

The integrated 20 W mono speaker is suitable for simple sound reinforcement; for professional installations, a dedicated sound system via the 3.5 mm audio output is recommended.

Connections and connectivity:

• HDMI: 2× HDMI 2.0 (HDCP 2.2)
• HDBaseT: 1× HDBaseT input – HDMI signal, control and network over a Cat6a cable, up to 70 m at Full HD
• LAN (RJ-45): Network control via web interface, PJLink, Crestron Connected, AMX, Extron and Telnet – full integration into professional room control systems
• RS-232: Control of power on/off, input selection, brightness, volume, freeze and status monitoring
• Wi-Fi: integrated (for wireless presentation via optional adapter or network access)
• USB-A: 1× USB-A (5 V/1.5 A – sufficient for streaming sticks such as Fire TV or Chromecast)
• Audio output: 1× 3.5 mm jack
• 12 V trigger: for automatic control of motorised screens
• 3D sync: for DLP Link 3D content

Mounting and installation

The ZK810T supports table placement and upside-down ceiling mounting and, thanks to 360° installation approval, can be operated in any orientation – including portrait mode for portrait projection in digital signage applications. The motorised lens shift offers ±55 % horizontal and ±25 % vertical image shift for precise optical alignment without loss of quality. The optical zoom (1.6×) and 4-corner correction add installation flexibility for curved screens and uneven surfaces.

The minimum ventilation clearance at the sides is 500 mm – take this into account when installing in racks or niches. Add around 7–12 cm to the housing depth of 43.3 cm for plugs and cable exit.

According to the manufacturer, the ZK810T projects image sizes from 50 to 300 inches.

The calculated throw distances are based on the manufacturer's throw ratio (1.26–2.10:1) and are intended as guide values. As the measuring points (e.g. from the centre of the lens vs. the front of the housing) often vary between data sheets, calculations accurate to the centimetre cannot always be guaranteed.

Security and operation: Kensington lock slot and PIN lock secure the projector against unauthorised use. The keypad can be locked so that only remote control operation is possible. Your own company logo can be loaded as a start-up image. The projector measures 486 × 432.5 × 185.5 mm and weighs 14.5 kg.

Running and follow-up costs

The laser unit of the ZK810T is designed for 30,000 operating hours – with no lamp replacement and no filter interval.

Power consumption is 530 W in Normal mode and 280 W in ECO mode; standby consumption is 0.5 W.

Which model is right for you?

The ZK810T and ZK810TST share the same laser platform with 8,500 lumens and 4K UHD – the key difference is the throw ratio and therefore where they are used.

Optoma ZK810T – ideal for

• Lecture halls, conference centres and seminar rooms with room depths from 3 m that need a bright 4K image even when daylight is not fully blacked out
• Digital signage and permanent installations with 24/7 requirements, where maintenance and downtime must be minimised
• Buildings with existing Crestron, AMX or Extron room control that want to integrate the projector seamlessly
• Installations in dusty or demanding environments thanks to IP5X dust protection of the optical unit

Have you thought of everything?

• Screen: For permanent installations, we recommend a fixed-frame screen for maximum flatness; for flexible installations, a motorised screen.
• Mount: For ceiling mounting, plan suitable ceiling mounts or, for motorised lowering, a ceiling lift .
• HDBaseT transmission: For signal feed over longer distances: PureLink 4K HDMI HDBaseT Transmitter with PoH – up to 40 m at 4K, up to 70 m at Full HD over Cat6a.
• HDMI cable: No HDMI cable in the box – HDMI cable to be chosen separately; for ceiling mounting, certified Ultra High Speed HDMI is recommended.
• Wireless presentation: For BYOD meetings without native casting: wireless presentation (AirPlay/Miracast/Google Cast) – from HDMI receivers to base stations for corporate environments.
• Sound: The integrated 20 W mono speaker is suitable for simple sound reinforcement; for larger rooms, a dedicated sound system is a good option.

Conclusion

The Optoma ZK810T combines 8,500 lumens of laser output with full 4K UHD display via DLP and a connectivity package that covers professional AV installations from simple PJLink control to Crestron/AMX/Extron integration. The laser unit with a 30,000-hour lifetime, 24/7 operating mode and IP5X dust protection reduce operating and maintenance costs over the entire installation period. Motorised lens shift and 360° installation freedom allow adaptation to almost any room situation without structural work.
