HDMI not detected at BIOS level or in OS

    I have created a video to make things more clear. I get no video detection via HDMI using Voyager. Works fine on next computer. 2nd monitor not seen in device manager (Windows). Computer displays fine to 'real' monitor though.
    Any ideas?

      Hmm, that's a tough one. Often when TinyPilot fails to connect to a laptop, it's because the laptop is not configured to display to an external display, but that doesn't seem to be the case here since the older laptop can display fine to a real monitor.

      Could you try connecting to the troublesome laptop and then share the logs with System > Logs?

      It might be that the laptop for whatever reason doesn't want to negotiate a video connection with the TinyPilot. Can you try applying a new EDID, described here?

          Or try plugging a monitor into the machine that said "NO SIGNAL" and see if it displays on the monitor.
          Change this in the BIOS setting usually.
