But you should really have a powered subwoofer, only the sound comes into its own.
I have the receiver connected to my PC via HDMI and everything works perfectly - image is in sync with the sound, immediately after switching the image appears, etc.
Also nice: The OSD (On Screen Display) - everything can be configured wonderful and I can directly control the input signal.
Perfect the sound was in my living room for automatic configuration via YPAD microphone - Simply connect the MIC and position at head height (I put on stacked boxes there) and run for a few minutes. Very comfortable :-)
