On the client, you want to make sure that you are playing a local copy if the path to the video file is the same as that on the server. That will avoid any video or audio conversion.
The settings on the client are then the only ones you need to worry about. Can you confirm in Windows what refresh rates your ASUS monitor is capable of?
I confirm that the refresh rates offered when configuring my Home Theater Zone on my Library Server are the setting of the Asus display attached to the Library Server PC and NOT the refresh rates of the front projector attached to the Home Theater client itself. So, apparently none of the Zone configuration settings shown on my Server as the Home Theater Zone's settings actually are that zone's settings. Why is that?
That'd be swell if the zone's settings takes the settings of the underlying playback system; that's what I'd expect or at least suggest as how it functions. But that is certainly not what all of the guidance on the forum is.
Is there another setting that enables the ability to configure the zone?
I will get a chance this evening to use JRemote to have the Server play through the Home Theater Zone and will be able to see what my pre/pro is receiving.
