Brightscript to instigate HDMI hotplug

Hello, 

 

I am changing HDMI output frame rate (resolution is the same at 3840x2160) using https://github.com/brightsign/video-mode-plugin , and it only sometimes works first time. Most of the time, it needs 3 attempts to get the change to occur on the TV. However, I have come to realise that if I replug the HDMI cable (after one of the failed attempts), it always works. So wondered if there is a way in software to instigate a HDMI hotplug. 

 

I did edit the above plugin to include: 

hdmichange = CreateObject("roHdmiOutputChanged")

but Im not sure this has any affect (doesnt seem to) - other than adding some "platform_nexus_display: HDMI hotplug event: connected" type entries in the log, which at first seem promising, but the actual behaviour of the TV remains the same. 

 

Thanks

    roHdmiOutputChanged is an event so you could listen for that event and keep sending the setmode() command. Are you changing modes on the fly during a presentation? Or, is this a one off change on boot?
