HDR data, HLG, and other HDMI® capabilities are not passed through or ingested.

The EDID that the BrightSign player advertises on the HDMI input claims 4K support for platforms which support 4K video output and have a 4K capable display attached. If the display doesn't support 4K or the platform doesn't support 4K video output, then the EDID reports modes only up to 1920x1080x60p. The EDIDs used as the basis for this can be found in the sys: drive on the players with the filenames default-edid.bin and default-4k-edid.bin. By default they report that the BrightSign player only supports stereo PCM audio. This is so that by default any audio coming in over the HDMI input can be mixed with audio from local playback. However, the values can be altered using roVideoMode’s ConfigureHdmiInput function which adjusts the EDID.

Tips

  • Set the video source to the same settings as the output. For example, if you are using 1920x1080x30p input, set the player’s output to 1920x1080x30p.

  • Interlaced input isn’t supported.

  • If it is an option, it can be helpful to test with the source set to no audio. Many input issues are caused by the audio setting.

  • If the HDMI input was working and then stops, it may be caused by the sleep option on the display. To test this, disable the sleep option and check if the HDMI input signal remains stable.
