Poly Studio X50 automatically starts presenting on PC wake

Hey folks. 

So, in addition to our Studio X50, we have a small form factor HP PC with Windows 10 in our conference room. 


It has 2 video outs (1 HDMI and 1 DP)
HDMI goes to Poly Studio X50 "HDMI IN" 
DP goes to TV via DP->HDMI cable 

This is so that you can use the computer with the TV separate from the Poly if you're just doing something solely internally in the conference room. 

However, we have noticed that if you wake up the PC - the Poly Studio X50 automatically enters Presentation mode and starts screen sharing. This happens regardless of the input you have the TV on. Wake the computer up and Poly starts presenting.

This is evident by the presentation light on the Poly, the TC8 indicates it's in Presi mode and then of course just switching inputs over to the Poly shows the screen shared. 

Any idea what's causing this?

Sorry for the late reply! But unfortunately that didn't fix it. 

CEC on both the TV *and* the Poly is disabled and it still does it. On wake or on meeting start... bam... automatic screen sharing.

I'm actually pretty sure I figured out the problem. 

Apparently for HDMI in connections, in the Zoom Room settings, you have to turn *off* automatic sharing and make it manual. 

Interesting that it's a default option.

I can confirm the above setting was the issue. 

I guess it assumes people won't leave anything plugged into the HDMI so, by default, it's set to auto start sharing if it detects an HDMI signal. 

Well we have a computer permanently plugged in for sharing purposes so it was always triggering that feature. I went into the ZOOM ROOM edit settings and turned on the "HDMI sharing always manual" feature.
