How to fix no picture on Lightware Matrix Switcher video output?
- P
  Patricia PatelAug 15, 2025
  If there's no picture on the video output of your Lightware Matrix Switcher, here are a few things to check: * Ensure all devices, including the matrix, are properly powered. Try unplugging and reconnecting them. * Verify all cable connections (video and TPS cables) are secure and fit well. * Check if the SIGNAL LED of the input port is lit. If not, there may be no incoming signal. Inspect the source device(s) and HDMI/CATx cable(s). * Confirm the correct video port is active by checking the video crosspoint settings. * Examine the TPS mode and ensure it matches the selected modes of the devices. * Check the mute state of the output port. Also, verify the emulated EDID; try selecting another one (for example, emulate the EDID of the display on the input port).

  If you're not getting any audio from your Lightware Matrix Switcher, consider these potential causes and solutions: * Ensure the source audio volume isn't too low or muted. Check the audio settings of the source. * Verify the correct audio port is active by checking the input port properties and the audio crosspoint settings. * Confirm that neither the input nor the output port is muted by checking their respective properties. * If using analog audio, check the Analog audio output port settings (volume). * If HDMI mode was set to DVI, check the properties of the output port and set to HDMI or Auto.

Why Lightware Matrix Switcher displays wrong picture on the video output?
- M
  Marco HillAug 25, 2025
  If the video output on your Lightware Matrix Switcher is not displaying the desired picture, it might be due to: * The video output being statically set to a test pattern (resulting in a no sync screen). Check the Test Pattern settings in the HDMI output properties. * The video output being set to a test pattern because there is no picture on the video source. Check the video settings of the source.
