Acer P1558i 5,200-Lumen Full HD Projector with 24/7 Approval and Portrait Mode

Acer P1558i – Full HD projector with 5,200 ANSI lumens, 24/7 rating and flexible installation geometry

The Acer P1558i is a standard-throw DLP projector with 5,200 ANSI lumens and native Full HD resolution (1,920 × 1,080 pixels, 16:9). It is approved for continuous operation (24/7), supports portrait projection and can be installed in any room geometry – even rotated through a full 360°. This makes it ideal for conference rooms, training rooms, digital signage applications and information displays that demand bright, reliable continuous operation with maximum placement flexibility. With 8.3 ms input lag, it is also below the practical threshold for smooth interaction. The 36-month manufacturer's warranty extends the planning horizon compared with the industry-standard 24 months.

Applications: what the Acer P1558i is ideal for

Conference rooms and training rooms

With 5,200 ANSI lumens, the Full HD image remains clearly legible even with the room lights fully on. Slides, spreadsheets and video conferencing content are displayed in native Full HD resolution. LAN allows integration into the company network for remote power-on and status monitoring. Automatic start on detection of an HDMI signal and Direct Power On mode reduce setup effort when presenters change frequently.

Digital signage and permanent installation

24/7 rating makes the P1558i a viable choice for information displays, exhibition stands and public exhibitions. Keypad lock and password protection secure ongoing operation against unintended input. Portrait mode allows narrow portrait-format projection for wayfinding systems and product presentations. With Direct Power On, the projector starts automatically as soon as the socket is live – no on-site switching on required.

Flexible installation with unusual room geometry

360° installation allows operation in almost any mounting position – even vertical or tilted positions that would be ruled out with standard projectors. The 1.3× optical zoom and throw ratio of 1.12 to 1.47 flexibly cover medium room depths. 4-corner geometry correction allows residual alignment if the mount cannot be placed exactly on the centre axis of the screen.

Picture and sound quality, connections

The P1558i uses a 0.65" DLP chip and delivers native Full HD resolution (1,920 × 1,080 pixels). The dynamic contrast of 15,000:1 provides well-differentiated image depth; HDR support activates automatically with compatible HDMI sources. In Eco mode (4,160 ANSI lumens), power consumption drops from 290 W to 210 W. The integrated 10 W mono speaker covers basic sound requirements; for presentation or training environments with higher audio requirements, an external active speaker system is recommended.

Connections and connectivity:

• 2× HDMI 1.4b – laptop and presentation PC, or signal source and monitoring, connected in parallel
• LAN (RJ-45): remote power-on via IP – useful for managed installations without on-site access
• RS-232: controls power on/off, input selection, brightness, volume, freeze, status monitoring – integration into room control systems without a LAN protocol
• 2× USB-A – peripheral connection and power supply for smaller devices
• Audio out (3.5 mm jack) – output to active speakers or a sound system
• Acer UWA5 Wi-Fi adapter included – the adapter adds Google Cast functionality

Setup, mounting and scope of delivery

The throw ratio of 1.12 to 1.47 (1.3× zoom) suits medium room depths without modification. The fixed offset of 132 % projects the image above the centre of the lens when placed on a table – and correspondingly below it when ceiling-mounted upside down. Keystone correction works vertically at ±40°, including 4-corner correction for residual alignment. Zoom and 4-corner correction are mutually exclusive; for permanent installations, first set the zoom to the desired image size and then activate 4-corner correction.

For ceiling mounting: M4 screws, max. 25 mm screw depth. The projector supports table placement, ceiling mounting and rear projection as well as any rotation angle, including portrait operation.

Throw distances at a glance:

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

Light source and running costs

The P1558i uses a UHP lamp. Operating time depends on the selected mode. In Eco mode, light output drops to 4,160 ANSI lumens with lower noise (27 dB instead of 36 dB) and lower power consumption (210 W instead of 290 W). In Dynamic mode, the lamp life extends to up to 15,000 hours. Once the lamp life has expired, the lamp must be replaced; a spare part is available separately.

If you would like to avoid lamp replacement in the long term, we will be happy to advise you on laser alternatives with up to 30,000 hours of light source life.

Which model is right for you? Acer P series at a glance

Within the Acer P series, the P1358i and P1558i complement each other on the same platform. If you prefer notebook content in 16:10 format (WXGA, 1,280 × 800) and accept slightly lower brightness, the Acer P1358i is a good choice. If you want full Full HD resolution (1,920 × 1,080, 16:9) and 200 ANSI lumens more brightness in reserve, choose the P1558i. Both models share the same 24/7 rating, portrait mode and 36-month warranty concept.
