In modern classrooms, teachers rely on BenQ Boards to present lessons, display digital materials, and interact directly with students through intuitive touch and writing tools. However, as lessons grow more dynamic—combining slides, videos, and annotations—many educators seek even more space to manage multiple types of content simultaneously.

At UAE University, professors were used to wide blackboards that offered plenty of space to explain concepts, compare ideas, and keep multiple notes visible at once. As classrooms transitioned to interactive displays, educators sought to maintain the same flexibility in a digital format by connecting a single Windows PC to two BenQ Boards placed side by side.

Initially, connecting a Windows PC to two BenQ Boards seemed simple. The HDMI and touch cables were set up, but the Windows system could not distinguish between the two boards. As a result, touch signals became misaligned: when a teacher tapped on one display, the input would appear on the other.

Teachers had to recalibrate or reset input sources after every PC reboot, which wasted class time and disrupted lessons.

Instead of providing a temporary fix, BenQ partnered with the university’s IT team to develop a permanent solution. Through several months of collaboration—including remote calls, on-site testing, and firmware updates—BenQ engineers developed a customized firmware that allowed Windows PCs to recognize each panel as a separate device.

The result was a seamless teaching experience: no more recalibration and no more lost time. Professors can walk into class, turn on the displays, and start teaching immediately with a quick, easy setup on their Windows PC.

The dual screen story began with the BenQ Board 03 series, when BenQ first recognized schools’ growing need for extended teaching spaces. By working directly with educators, BenQ’s team developed a customized solution to meet this challenge.

By continually listening to user feedback and understanding real classroom needs, BenQ improved this feature in the next product generation.

• RP & RM 04 series: With firmware v20250115 or later, RP04/ RM04 BenQ Boards can output via HDMI Out to one external display for Duplicate or Extend, while also carrying audio.

This approach shows how BenQ turns classroom feedback into real innovations that make teaching smoother and more adaptable.

With BenQ’s dual screen solution, teaching becomes more versatile:

• Extend Windows across two panels – Teachers can display slides on one panel while researching or annotating on the other, making lessons more dynamic.
  

• Combine OS platforms – Windows applications run alongside BenQ’s EZWrite 6 or InstaShare 2 for interactive, multi-platform lessons.

• Duplicate content for visibility – Content can be mirrored on both displays, ensuring students across the classroom have a clear view.

FAQ: Can I use InstaShare 2 extend mode to mirror my PC on two BenQ Boards?

No. InstaShare 2 supports sharing from a PC to one BenQ Board at a time. If you need to mirror or extend across two boards simultaneously, Dual Screen is the right solution.

For educators, presenting multiple streams of information simultaneously is crucial. BenQ Dual Screen enables teachers to explain concepts while comparing examples, displaying references, or showcasing student work side by side, eliminating the need to switch between windows and minimizing interruptions.

This solution removes the barrier of limited screen space, providing educators with the same freedom they once enjoyed with wide blackboards, now in digital format.

Dual Screen is more than just a feature—it’s a direct response to real classroom needs. By addressing these challenges head-on, BenQ demonstrates its commitment to providing educators with practical, reliable, and customized solutions.
