Acer PL6820 5,500 Lumen 4K UHD Laser Projector with Lens Shift and 24/7 Operation for Business

Acer PL6820 – 4K UHD laser projector for professional permanent installation

The Acer PL6820 brings 4K UHD resolution (3,840 × 2,160) to Acer's PL installation series – with 5,500 ANSI lumens, a laser lifetime of up to 30,000 hours in ECO mode and the series' full network control package. On large projection surfaces, 4K delivers noticeably sharper text, finer graphics and more precise CAD output than Full HD or WUXGA projectors. With an input lag of 4.2 ms, the PL6820 is also suitable for real-time applications such as simulator systems, training environments and interactive large-screen solutions. Native support for Crestron, PJLink, AMX, Extron and Telnet means it integrates directly into professional AV control infrastructures.

Benefits and special features

• 5,500 ANSI lumens – daylight-capable in lit conference and event rooms
• Input lag: 4.2 ms – real-time response for simulators, interactive systems and training environments
• Laser light source: 20,000 h normal / 30,000 h ECO – no lamp changes during operation
• Approved for 24/7 continuous operation – for digital signage and information displays
• Network control: PJLink, Crestron, AMX, Extron, Telnet via LAN (RJ-45)
• Vertical lens shift +54 %/–49 % – flexible ceiling mounting without keystone correction
• 360° installation and portrait mode – operation in any orientation

Applications: what the Acer PL6820 is suited for

4K display in conference rooms, lecture halls and showrooms

With 5,500 ANSI lumens, the PL6820 delivers a clearly legible image even in rooms with the ceiling lights on. 4K resolution shows its advantage wherever detail matters: text is razor-sharp, architectural and engineering plans are displayed pixel-perfect, and high-resolution photos in showrooms or exhibitions look their best without screen-door effects. PJLink, Crestron, AMX, Extron and Telnet allow central management via existing AV control systems.

Simulators, training rooms and interactive large-screen solutions

An input lag of 4.2 ms is exceptionally low for a 4K installation projector in this lumen class. Simulators, driver training, interactive board systems and response-critical training applications benefit directly: the delay between input and image output is imperceptible to the human eye. Combined with approval for 24/7 continuous operation, the PL6820 is suitable for training centres running around the clock.

Digital signage and information displays

Approval for 24/7 operation combined with automatic start when mains power is applied makes the PL6820 a reliable choice for permanent installations in foyers, exhibition halls and public buildings. Portrait mode allows portrait projection – for narrow information columns and digital signage in 4K quality. Wall colour compensation digitally corrects for coloured surfaces when no screen is available.

Picture and sound quality

The PL6820 uses DLP technology with a 0.67" DMD chip and outputs the image in 4K UHD (3,840 × 2,160). The gain in sharpness over Full HD is clearly visible on large projection surfaces: text stays legible right to the back rows, and fine lines in plans and diagrams resolve cleanly. With 5,500 ANSI lumens and a contrast ratio of 50,000:1, it delivers high-contrast images with room lighting. HDR (HLG) is supported. 3D playback is via DLP Link.

The integrated audio system delivers 2 × 15 W (30 W total) – sufficient for speech intelligibility in medium-sized rooms. For room-filling sound in large lecture halls or event spaces, we recommend an external sound system.

• 2× HDMI (1.4b + MHL/HDCP) – two signal sources can be connected at the same time
• LAN (RJ-45): network control via PJLink, Crestron, AMX, Extron, Telnet
• RS-232: power on/off, input selection, brightness, volume, freeze, status monitoring
• USB-A (1×): power supply for adapters or control peripherals
• Screen mirroring (Miracast) via optional Acer UWA adapter – wireless BYOD integration
• HDMI-CEC: automatic source control when switching devices

Mounting and installation

The PL6820 supports table placement, ceiling mounting (inverted) and rear projection – as well as all angles in between thanks to 360° installation. The vertical lens shift of +54 %/–49 % allows flexible optical image positioning without keystone correction. The 1.7× optical zoom provides additional latitude when planning the distance.

Throw distances (PL68xx platform, similar throw ratio ~1.20–2.04:1):

Also allow for the housing depth (26.5 cm) plus approx. 7–12 cm for plugs and cable exit. Minimum side clearance for ventilation: 10 cm on each side. The projector measures 337 × 265 × 123 mm and weighs 4.9 kg.

Security features: PIN lock (password-protected interface against unauthorised access).

Running and follow-up costs

Power consumption: 235 W (normal) / 195 W (ECO) / 0.5 W (standby).

No regular lamp replacement required – the laser light source is low-maintenance in continuous operation.

Target groups at a glance

• AV integrators and IT departments running Crestron, AMX or Extron systems
• Showrooms, exhibitions and presentation rooms with the highest demands on sharpness
• Simulators, training rooms and interactive large-screen systems with real-time requirements
• Operators of digital signage installations with 24/7 requirements and 4K content

Models compared – Acer PL series

You will find all three models of the Acer PL series in our shop – for personal advice, get in touch with our projector experts.

Have you thought of everything?

• Screen: For fixed installations, we recommend a fixed-frame screen – maximum flatness, no flapping from air conditioning. For flexible use: motorised screen.
• Ceiling mount: For stable ceiling mounting, you will find suitable mounts in our projector ceiling mount category.
• HDMI cable: An HDMI cable is included – for ceiling mounting or a greater distance to the signal source, you will need a longer one. You will find suitable cables in our HDMI cable range.
• Wireless presentation: For BYOD meetings without hunting for cables: wireless presentation with AirPlay, Google Cast and Miracast – plug-and-play presentation without admin rights.

Conclusion

The Acer PL6820 is the resolution step-up within the PL installation series: 4K UHD, 5,500 ANSI lumens of daylight brightness and the full network control package (PJLink, Crestron, AMX, Extron, Telnet) in the same housing as its FHD and WUXGA siblings. The input lag of 4.2 ms is exceptional for a 4K installation projector in this lumen class – opening up the PL6820 to real-time applications for which other installation projectors in this class respond too sluggishly.
