Onkyo TX-SR875 - HDMI source trouble (PC, Xbox and other)

I have a problem with connecting to the HDMI source.
I am currently have one working device via HDMI - satellite decoder.
But I need to connect PC and other devices.

The following sources is not working:
* ASUS EAH4350 (ATI) (PC)
* nVidia Corporation GT218 [GeForce 210] (PC)
* Raspberry pi (micro PC)
* xbox 360 (Gaming console)


My actual version of firmware:

---

Main: 87 1.08
MainUpdateMode Ver1.01/07615L
DSP 1st: SR8051 07601A
DSP 2nd: SR8052 07518A
DSP 3rd: SR8053 07518A
HDMI: 1.01/07706A
Video: 07606E00924ok

On the AVR display: No Signal



Can anyone recommend some firmware upgrade?

This receiver makes me mad, I'm disappointed. Wasted money. I do not recommend Onkyo TX-SR875.

People recommend to buy an HDMI splitter and connect to the TV for the picture and the sound separately to onkyo - for me nonsense.

Problem with Raspberry Pi resolved!

You need to disable EDID and set the resolution manually.

This should help raspberry pi users.
My WORKING /boot/config.txt:
...
hdmi_ignore_edid=0xa5000080
hdmi_group=1
hdmi_mode=4
hdmi_force_edid_audio=1
hdmi_drive=2
...

Thanks for your help.

I like the term to describe the "hdmi_ignore_edid":
"Enables the ignoring of EDID/display data if your display is a crappy Chinese one".

They mean my AVR?
