Hey, I just want to inform you, that the current update to LE9.2.1 could be contain problems with Hyperion. In my case I am not able to view 1080p x264 content without signal drops. This was only the case at 4K footage or HEVC content with high bitrates. With a downgrade to the 9.2.0 version the same clips play without problems including the Hyperion Ambilight.
Maybe they did some fixes which are responsible for a higher cpu load in idle than before.
Do you notice similar problems with the latest version?
