Lightware Hdmi Switcher

[Theodora Wallingford]

Weare having an issue with a G7500 when switching to Device Mode (BYOD) where the codec does not recognize that a HDMI source is connected and shows the blue screen prompting for a HDMI cable to be connected. The current configuration consists of a Lightware MMX2- 4x4-H20 video switcher which feeds the content in of the G7500 via it's HDMI port. When the codec is in normal operation, running in Zoom mode. The codec can see the HDMI output from the Lightware. We can share the Barco Click Share and laptop inputs to the G7500 without issue. When we switch the codec to BYOD mode it looses sync with the lightware and can no longer see the HDMI output, even though there is a source connected. Anyone have any experience with this.

is the device staying in device mode and you only change the source of the HDMI or are you switching between modes on the Poly device aka between Device mode and for example Teams and then HDMI share?

Yes, we switch between modes. G7500 running Zoom client and device mode for BYOD. HDMI ingest works fine when in Zoom mode, when switched to device mode, the G7500 does not recognize the connected HDMI source. Leads me to think that there may be an EDID issue at play.
