Infrared 6 Points Touch Technology
Pair the IL420 with Windows® 8 / Windows® 7 and watch the infrared touch technology work its magic turning the displayed image or spreadsheet figure into a multi-touch screen. Trainer or speaker can invite audiences to come up to the board for a quick contest and trial.

Ambient Light Sensor
The IL420 is built with an ambient light sensor to detect the amount of ambient lighting in its surrounding and adjust the display setting accordingly without user intervention. This means the audience can always enjoy optimal picture quality in office.

Integrated Speaker
To help professional elites gain the competitive edge by enriching their meeting with multimedia resources, BenQ has built 12W speakers into the IL420. The use of videos, music and sound effects make every presentation more engaging and effective.


6-point Multi-Touch Display

Based on the infrared (IR) technology, this advanced design eliminates most "dead zones" and boosts pointing precision. 6-Point Multi-Touch provides users enhanced interactivity by allowing multiple people to participate in any given presentation. The new dust-proof sensors enable more reliable performance in both in portrait and landscape modes.

Anti-Image Retention

The IL420 panel is specifically designed for digital signage and eliminates the risk of burned-in effect even after an extended period of usage. This is perfect for designing dynamic content that can utilize the whole screen without distracting ghost images.

Easy Interactive Video Wall Without a Splitter

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.

Picture-in-Picture (Pip) & Picture-by-Picture (PbP) Modes

The picture-in-picture and picture-by-picture modes enable the screen to display content from two independent video sources simultaneously for more convenience and flexibility. You can resize or relocate the picture anywhere on the screen for maximum effect.

Energy Saving Ambient Light Sensor

An integrated sensor automatically adjusts screen brightness according to the lighting condition of the surrounding environment to optimize the image and reduce power when it's not needed. As the brightness adjusts to the ambient light, the display can reduce energy consumption by 40% to 50%.

Portrait Mode Optimized

Traditional digital signage panels displayed in portrait mode tend to experience a lack of image uniformity. Dark spots or patches may appear on the edges and distort the image-this phenomenon is known as Mura. BenQ's IL420 is designed to prevent this effect thus optimizing image uniformity for images displayed in portrait mode.

DisplayPort - Expand to all Connectivity

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.
