I plan to install a 75" IFPD in my 60-seater classroom. The classroom size is 25 ft by 40 ft. I’m afraid that the students at the back won’t be able to view the content displayed on the IFPD clearly.
Recommended Setup Overview
Primary Display (Front-Center):
- 75” Teachmint X2 Pro IFPD (4K) with integrated 8-array microphones, camera, and 40W speaker system
- Suitable for medium to large classrooms
- HDMI Out support (up to 30 meters) for connecting external displays
Additional Display (Optional but Recommended):
- Add 1 ceiling-mounted 65”–86” TV or commercial LED display placed approximately 30 meters from the IFPD
- Mount at an angle that ensures clear visibility from far-left, far-right, and back rows
- Especially useful in wide or deep classrooms for improved engagement
Wired HDMI Connectivity:
- Use HDMI 2.0/2.1 cables or HDMI extenders (HDBaseT/fiber) for stable signal transmission over long distances
- Connect: Teachmint X2 Pro HDMI Out → External Display HDMI In
Audio Setup (External Optional):
- For enhanced coverage:
- Use an external soundbar or active speakers (via 3.5mm Aux or HDMI ARC)
- Add ceiling or wall-mounted speakers with amplification for uniform sound
- Consider a wireless mic system for mobility
- Audio output can be connected via audio out port or HDMI extractor
Visibility & Environment:
- Wide 178° viewing angle ensures visibility from all sides
- Minimize glare with controlled lighting
- Maintain at least a 2-inch ventilation gap around the device
Final Recommendations:
- Test HDMI signal strength and audio clarity before finalizing the setup
- Ensure content is legible and audio is synchronized across the room
- Enable display scaling if screen resolutions differ
