Solved! Go to Solution.
Response from elsewhere I went to (we = Polycom):
The YPrPb we specify is TRI-level sync.
Usually the bi-level sync kinda-sorta works but is flaky (flashes and blue-screens).
Tri-level sync is the only HD analog form that is reliable with our HDCI inputs.
Additional information, from the same person who provided the initial response.
BTW… here’s a nice reference about tri-level sync.

Dear Steven!
Thank you for answer. Once more question: what about input 4 of GS 700? Does it work with Bi-level sync component signal?
Here again, we may have a misunderstanding of the port configuration.
That port is intended for YPrPb with tri-level sync.
The port DOES support Composite video 480i on the yellow connector.
YPrPb in our environment demands tri-level sync.
Dear Steven!
Thank you for such full qualified answers! I really appreciate your help!
I knew that HDX lineup requires tri-level sync, but wanted to verify this against GS lineup.
Threre is article 14021 in knowlege base about it. (HDX)
