How to project IFP screen to two TVs?

Teachmint X Buying Guide Hardware

I’m planning to install an IFP in a 250-seater auditorium. I want to put two large displays on either side of the IFP so that the audience can see the content displayed on IFP easily. How can this be done?

:white_check_mark: Recommended Setup Overview

:desktop_computer: Primary Display:

86" Teachmint X2 Pro IIP (4K Resolution)

  • In-built Camera, 8 Array Microphones, 20W + 20W Speakers with Subwoofer
  • Serves as the central display and audio-visual command unit

:television: Side Displays (Audience Visibility):

  • Two 65"–86" LED TVs, commercial displays, or Teachmint IIPs
  • Positioned on either side of the main IFP for optimal side-seat visibility

:electric_plug: Connection Plan – HDMI Splitter Setup (Wired, Reliable)

:wrench: Required Components:

  • 1x HDMI Splitter (1 input → 2 outputs)
  • 3x HDMI 2.0/2.1 Cables, minimum 20 meters (quality matters over long distance)
  • Optional: HDMI Extenders (HDBaseT or fiber HDMI) for distances over 20 meters

:puzzle_piece: Connection Steps:

  1. IFP HDMI Out → HDMI Splitter Input
  2. Splitter HDMI Outputs → HDMI cables → Side Displays
  3. Use display scaling on the side displays if they differ in resolution or aspect ratio.

:microphone: Audio and Mic Consideration

  • Built-in Teachmint X2 Pro IIP audio is powerful (40W total with subwoofer)
  • For larger halls or professional audio, connect an external audio system to the IIP via:
    • 3.5mm audio out
    • HDMI ARC/eARC
    • Bluetooth
    • Optical out (if supported)

:brick: Installation Guidelines

:round_pushpin: Location & Mounting:

  • Install the main IFP at the front center of the classroom
  • Mount side displays at angles visible to far-left and far-right student areas
  • Follow universal accessibility standards (reachable by wheelchair users)
  • Avoid placing near doors, heaters, or walkways

:high_voltage: Power and Network:

  • 1-meter proximity to a 6A/16A power outlet
  • Ensure network port for wired internet access (if used)
  • Use a UPS for protection and longevity
  • Professional electrician required for earthing and new outlet setup

:light_bulb: Lighting & Visibility:

  • Screen visible within a 178° viewing area
  • Avoid window glare and direct lighting above the screen
  • Consider ambient lighting adjustment or anti-glare films

:wind_face: Ventilation & Environment:

  • Leave 2" (5 cm) space on all sides for airflow
  • Avoid strong dust sources, vibrations, and direct air from HVAC vents

:straight_ruler: Height Consideration:

  • Consider average height of users (teachers/speakers)
  • Follow interactive panel mounting height standards – generally, the center of the screen should be around 1.2 to 1.4 meters from the ground (for standing interaction)

:pushpin: Final Tips:

  • Test setup before full deployment — check for audio sync, latency, and visual clarity
  • If using long HDMI cables, test signal strength; active HDMI or extender may be required
