BenQ LW555C 3,500-Lumen WXGA Laser Projector for Meeting Rooms

BenQ LW555C – compact WXGA laser projector for meeting and training rooms

The BenQ LW555C is a compact WXGA laser projector with 3,500 ANSI lumens for meeting, conference and training rooms. The low-maintenance light source runs for up to 20,000 hours, the RS-232 serial interface integrates it into room control systems, and auto keystone correction aligns the image quickly. At 3.0 kg, it moves effortlessly from room to room.

Key benefits at a glance

• 3,500 ANSI lumens in WXGA: Slides, tables and graphics remain easy to read even with the room lights on.
• Low-maintenance light source: 20,000 hours in normal operation, no lamp replacement in continuous use.
• RS-232 control: integrates the projector into media control systems via a serial interface and allows central operation without a network on the projector.
• Quick alignment: Automatic keystone correction and 4-corner adjustment compensate for image geometry if the mounting position is not exactly centred on the screen.
• Wall colour correction: electronically compensates for coloured projection surfaces and delivers neutral colour reproduction even on yellow, green or blue walls.
• SmartEco technology: Adapts laser output to the image content and reduces power consumption and noise without any visible loss of quality.

Is the BenQ LW555C the right choice?

• Yes, for classic meeting, conference and training rooms up to around 150 inches, where a bright WXGA image from a standard distance is needed and the projector is to run with low maintenance in continuous operation.
• Not ideal, if several image sources are to remain permanently connected at the same time: the LW555C has one HDMI input. For two fixed sources, a model with two HDMI inputs is a better fit, such as the Acer XL2330W.
• Not suitable, for Full HD or 4K video playback in 16:9 – you will find suitable devices under Full HD projectors.

For a rich image in daylight, we recommend an daylight or contrast screen, mounted on a suitable ceiling mount.

Applications: what the BenQ LW555C is suited for

Meeting and conference rooms
With 3,500 ANSI lumens and WXGA resolution, the image remains legible even with the ceiling lights on – slides, tables and graphics are clearly visible on a 100-inch screen (approx. 2.14 m wide). The native 16:10 format reproduces classic laptop screens without cropping, so full-screen presentations use the entire surface.

Training and seminar rooms
In training sessions, the LW555C starts immediately after switching on with no warm-up phase. Your own company logo can be stored as a start-up image, and password protection secures the device against unauthorised use. Using the page buttons on the remote control, presenters can move forwards and backwards through PowerPoint slides as soon as a USB cable is connected to the computer.

Flexible presentation use
At 3.0 kg and measuring 304 × 225 × 112 mm, the LW555C can be relocated quickly – from the conference table to the seminar room, from the office to a sales appointment. Auto keystone correction saves set-up time when moving, and the light source needs neither warm-up time nor lamp replacement.

Picture quality of the BenQ LW555C

The 0.65" DLP chip works together with the light source to achieve 3,500 ANSI lumens at full brightness. In business use, the dynamic contrast ratio of 3,000,000:1 helps above all with fine lines, tables and dark chart areas. DLP technology produces a sharp pixel structure, which is a visible help with text slides, charts and tables.

The SmartEco function automatically adapts the laser output to the image content. In dark scenes, brightness, power consumption and noise drop to as low as 28 dB(A). In training rooms where quiet matters, this makes a noticeable difference. Wall colour correction also compensates for coloured projection surfaces, so colour reproduction stays neutral even without a white screen.

Connections

Connections at a glance:

HDMI, 1×

Digital video input for presentation PCs, notebooks or video conferencing systems. High Speed HDMI cables are sufficient for WXGA, even with ceiling mounting. An active HDMI cable only makes sense from a cable length of around 15 m.

USB Type A, 1×

For firmware updates and presentation control: with a USB connection, you can scroll through PowerPoint slides using the page buttons on the remote control. The port also supplies 5 V / 1.5 A to power small devices.

RS-232

Serial control interface for integration into room control systems. Power on/off, source selection and status queries can be addressed centrally without a network connection on the projector.

Audio out, 3.5 mm jack

Passes the audio signal on to external speakers or a PA system. The integrated 15 W mono speaker provides basic sound – if speech intelligibility matters to you, add an external system via this output.

Security Kensington lock + PIN

Mechanical theft protection and password protection for seminar and conference rooms with changing audiences.

Note on wireless presentation: The LW555C has no integrated Wi-Fi. You can add wireless casting via an HDMI casting receiver or the optional Wireless Casting Dongle (QP30) with Miracast – you will find a specific recommendation in the accessories section.

Light source & operation

Mounting & installation

The BenQ LW555C is suitable for table placement, wall and ceiling mounting. At 3.0 kg, it is light enough for any conference table and easy to fix to the ceiling; the ceiling mounting points use M4 screws.

The lens has a fixed offset. When ceiling-mounted, the projector hangs upside down; position the mount so that the centre of the screen and the centre of the lens are at the same height. If a small residual offset remains, it is compensated by automatic keystone correction (±40° vertical and horizontal) or 4-corner adjustment. In fixed installations, it pays to carefully align the mount position with the screen axis before correcting digitally.

You will find suitable projector ceiling mounts and projector ceiling lifts for the LW555C in our shop.

Throw distance (screen size 16:10, TR 1.55–1.70:1):

The projector measures 303.5 × 224.6 × 112.4 mm and weighs 3.0 kg. Allow an additional 7 to 10 cm for plugs and cable exit.

BenQ LW555C vs. Acer XL2330W vs. BenQ LU785 – which business laser projector suits your room?

The LW555C is the quietest in normal operation (31 dB(A)) and is the compact standard-throw projector for classic meeting rooms. If you need the higher WUXGA resolution (1,920 × 1,200) for detailed tables, plans and CAD content with the same set-up, choose the BenQ LU785; if you want maximum light reserves for large or bright rooms, choose the Acer XL2330W with 5,000 ANSI lumens.

Have you thought of everything?

• Screen: For bright rooms with daylight, we recommend ambient light rejecting and high-contrast screens; for darkened training and conference rooms, a standard motorised screen.
• Mount: You will find suitable ceiling mounts for standard installations and projector ceiling lifts for discreet permanent installations directly in our shop.
• HDMI cable: Suitable High Speed cables for connecting the projector can be found under HDMI cable.
• Sound: The integrated 15 W mono speaker provides basic sound. For rooms where speech intelligibility matters, we recommend the celexon active speaker set via the 3.5 mm audio output.
• Wireless presentation: A receiver for wireless presentation plugs into the HDMI input and enables wireless casting from a laptop or smartphone.

Frequently asked questions about the BenQ LW555C

How can guests present wirelessly?
Via a casting receiver: a system for wireless presentation plugs into the HDMI input, and guests can then share their screen without any IT configuration on the projector.

Does the projector have to hang exactly centred on the screen?
No. The fixed offset allows table and ceiling mounting; automatic keystone and 4-corner correction compensate for minor deviations from the screen axis.

How often does the light source need maintenance?
Never – the light source is maintenance-free and lamp changes are eliminated entirely (for service life, see the table "Light source & operation").

How do I control the LW555C centrally without a network connection?
It integrates into room control systems via the RS-232 serial interface – without any LAN port, which is often the more stable option in fixed installations.

Is WXGA enough or do I need Full HD?
WXGA (1,280 × 800, 16:10) is sufficient for slides, tables and presentation tools. Only if you mainly show Full HD video in 16:9 should you opt for a Full HD model – you will find them under Full HD projectors.
