BenQ's Newest Interactive Flat Panel - 42 Inches of interactive brilliance for digital signage

6-point Multi-Touch Display

Based on the infrared (IR) technology, the IL Series offers the highest number of touch points in the current digital signage market. The advanced design eliminates most “dead zones” and boosts pointing precision significantly, while the sensor package is now dust-proof and more reliable in portrait mode comparing to competing products.


The MDA (Multiple Display Administrator) application controls up to 98 displays simultaneously through the local network or serial port; it also monitors the health of displays and coordinates a sequential startup to prevent power surges.

  BenQ PID   Conventional  

Optimized for Portrait Mode

BenQ puts extra attention on scenarios in which portrait mode communicates better. The PID panel employs a structure featuring more solid fixing points on all edges to prevent “Mura” image distortion common on vertically positioned consumer displays.


DisplayPort is a new standard for digital audio/video transmission. With the whopping 10.8Gbps bandwidth, the DisplayPort keeps your contents attractive, distortion-free in longer distances than conventional DVI and HDMI.

RS232 / LAN Control

BenQ IL Series supports remote administration via the built-in RJ45 Ethernet or the RS232 serial interface. Routine tasks such as OSD settings and firmware upgrades can be performed on the control server to the daisy-chained displays.

Anti-Image Retention

In commercial environments where images would stay for hours, image retention becomes a problem on consumer displays. PID panels designed for digital signage prevents the burned-in effect even after an extended period of usage.

  Image Retention Free   Shift to Other Image   Image Retention  


24 / 7 Operation

The IL Series has an amazing average life of 50,000 hours – enough for years of non-stop service. With the reliable industrial-class performance, sturdy build and touch functions, the IL Series is in fact more versatile and economic then consumer models.


Ambient Light Sensor

A sensor automatically adjusts screen brightness according to the lighting condition of the surrounding environment. Since the power usage adapts intelligently with the ambient light, the display can reduce energy consumption by 40% to 50%.

  Comfortable brightness for high ambient light environment But too high brightness makes eyes stressed and tired  


PiP / PbP

The PiP/PbP feature displays contents from two independent video sources simultaneously for more convenience and flexibility. The PiP mode allows the sub picture to be resized or relocated for the best presentation.

Scheduling Management

The feature enables users to designate up to seven sets of on/off time for IL Series displays down to individual video input sources. This not only eliminates the need to switch displays on/off manually, but also cuts power bills with precise agendas.


Analog Daisy Chain

Analog Daisy Chaining is the easiest way to build a video wall. You can simply connect up to 9 displays through VGA cables without using splitters; the screens can show a mirrored image, or form a 3x3 configuration for an enlarged viewing area.
