Can you please try without the AVR? Try doing a direct connection. Also, can you attach the dxdiag report here?
How to get it?
Dxdiag Report: Type dxdiag in Start Menu> open> Save> Attach using Advanced Editor Options.
direct connection is ok but I need to connect it through AVR.
Directly I have only stereo...
DxDiag connected to TV or AVR?
Try updating the BIOS to latest:
It is also important to get the latest firmware for the AVR from the device manufacturer.
