8. Troubleshooting

  • No Display: Ensure the monitor is powered on and all video cables (HDMI, USB-C, VGA, AV) are securely connected to both the monitor and your source device. Try different cables or ports if available.
  • Touch Function Not Working: Verify that the USB-B cable is correctly connected from your device to the monitor. Confirm your device's operating system (Windows/Chromebook) is compatible with the touch function. Note that gaming consoles and some Apple products do not support touch.
  • No Sound: Check the monitor's volume settings via the OSD menu. Ensure your audio source is correctly selected and that any external headphones/speakers are properly connected to the earphone jack.
  • Touch Screen Effect Displayed on Main Screen (Windows): If the touch effect is incorrectly displayed on your main laptop screen instead of the portable monitor, you may need to calibrate the touch screen. Access the 'Control Panel' -> 'Hardware and Sound' -> 'Tablet PC Settings'. In the 'Display Options', select 'InnoView' (or the corresponding name for your portable monitor) and then click 'Setup'. Follow the on-screen prompts to tap the portable monitor to identify it as the touchscreen.
