Xbox connectivity problem

I'm having the same problem with my Wii output. The manual for the Denon AVR-1312 says that analog video signals (i.e. component/composite outputs from the Wii) are not converted to digital video signals (i.e. HDMI output from the rcvr). I'm running only HDMI to a projector, so the video signal is essentially lost. The fix appears to be to run an additional composite cable all the way to the projector. Sounds like your fix is the same. No Wii tonight! :(

This receiver doesn't support processing of video signal, only switching. This means that it can output only the same format of video. Only some more expensive models do upscaling from component/composite to HDMI out.

From HDMI out, you can output only signal that came via HDMI in 1-3. For component out, you can output only component in. The same for composite.

So in order to use wii through receiver to TV, you must connect receiver and TV also via the component cables.

Or other option is to connect component from wii directly to TV and connect only audio to receiver.

Connect Xbox via HDMI to DTV/IN, Connect HDMI from out to Sony Bavia's HDMI/IN. Connect TV's Optical out to amps DTV/Optical in.

2X HDMI cables and one Optical are required.

Enjoy great sound :)

OH: choose the DTV input then stereo and then dolby 5.1 etc .. cheers

For some reason you can only have the component leads with optical cable, if you put hdmi cable in there is no connection for the opticle cable out.

Is the problem that you're using a single HDMI cable to connect your Xbox to your TV? If so, this Turtle Beach article should help... ________________________________________
HDMI and Connecting Ear Force Xbox Headphones
The current Microsoft Xbox 360 series of gaming consoles allow the use of HDMI cables for simpler hookup to home theater systems and Hi-Definition televisions (HDTV).
The Xbox 360 Elite (the black one) comes with two additional cables, an HDMI cable and a separate AUDIO cable that provides a pair of RCA jacks (red and white) and an optical digital audio output (S/PDIF Out). With this cable package, you can easily connect any of our X-series headsets and an HDMI-connected television at the same time.
This Xbox 360 HDMI Cable package is available as an extra-cost option from Microsoft: http://www.xbox.com/en-US/hardware/x/xbox360hdmiavcable/
Here's a more in-depth explanation of the Xbox 360 HDMI Cable and how it works: http://support.microsoft.com/kb/937899?sd=xbox
[NOTE 1:] The standard Xbox models do not come equipped with this cable set. The HD cable they have obscures the HDMI connector, so that the two sockets cannot be used at the same time. If you only have this stock HD connector (component video, composite video, stereo analog audio and optical digital audio connectors), then you will not be able to use the HDMI connector at the same time.
In order to use both sockets at the same time (HDMI and A/V) you'll need to purchase the Xbox 360 HDMI Cable package described above.
[NOTE 2:] The current Xbox 360 Elite Holiday Edition (Fall 2009) does not come with the HDMI Cable set.

Some companies make aftermarket HDMI cables for use with the Xbox 360, but these may not provide the dual RCA jacks that carry the 2- channel analog audio necessary for hookup of the anlog-only Ear Force X-series headsets. If this is what you have, you may need to find another way to connect your Ear Force X-series headset.
The TOSLINK digitally-connected X-series headsets can be always be connected using optical digital "Toslink" connections (and that's the best way to use them!).
___________________________________________________________________
The oldest white-and-gray Xbox 360 models DO NOT have an HDMI port. With this particular (obsolete) model, you cannot use HDMI connections, but you can use any of our X-series headsets.
Current Xbox 360 models all have separate HDMI and A/V ports ("sockets") on their back panels.

Here are some suggestions for alternative connection schemes:
XBOX 360 AUDIO PLAYS THROUGH TELEVISION SET:
For X4 and X41: Your best bet would be to connect the Xbox optical digital audio out to the X4 transmitter's optical digital input. Then connect the X4 optical digital output to the optical digital audio input on your HDTV or home theater amplifier.
[NOTE:] Some HDTV systems have an optical digital audio output that will not transmit Dolby Digital/DTS encoded digital audio, only stereo PCM audio will be passed. In this case, you must connect as above.
For X2, X3 and X31: You can use the Headphones jack or the Audio Out jacks on your TV to connect to the Audio In jack on the Transmitter.
For X1 and X11: You can use the Headphones jack or the Audio Out jacks on your TV (if available) to connect to the headset's analog Audio Input.

NOTE: Please make sure your TV has Audio Out jacks. Some TV's only have Audio In jacks.
Audio In jacks only accept incoming audio signal; they do not send audio signal out. If no audio signal is being sent to the headset, no sound will play from the headset.
___________________________________________________________________
You may need to purchase a suitable adapter cable in order to connect the TV audio output(s) to the Ear Force X-series headset's transmitter or Audio Input plug.
- Connect the HDMI cable so that the Xbox 360 plays its audio through the TV.
- For X1, adjust the Dashboard > Settings > System > Voice in the Xbox 360 so that the talkback and game sounds are played together (Play Through Speakers). - For X3, X31, X4 and X41, you should set this to Play Through Headset.
__________________________________________________________________
XBOX 360 AUDIO PLAYS THROUGH HOME THEATER RECEIVER (except X4 and X41): This is exactly the same as the above, except that you will use the receiver's Headphones output jack to connect to the Audio In on the Ear Force Xbox-compatible headset's Transmitter (X2, X3, X31) or the green Audio Input plug (X1).
- You may need to obtain a shielded audio cable with 1/4" stereo phone plug to 1/8" stereo mini-phone plug ends. The 1/4" phone plug goes to the receiver's Headphones jack, while the 1/8" mini-phone plug goes to the Audio In on the Ear Force Transmit- ter (X2, X3, X31) or Audio Input plug (X1).
- Adjust the Dashboard > Personal Settings in the Xbox 360 so that the talkback and game sounds are played together (Play Through Both). For X3 and X31, you may also set this to Play Through Headset.

The W3201c IS 720P. You have to adjust the display output on the xbox 360 to 480p then adjust settings up from there...

You cant have HDMI and the xomponent cables pluged in at the same time.
to get audio to your monitor you will need an xbox 360 audio adapter. You can find that here. http://www.xbox.com/en-us/hardware/x/xbox360hdmiavcable/default.htm

That comes with the HDMI and audio adapter.
You can probabaly find it seperate somewhere else.

I hope this helps.

1. Connect your set-top box HDMI output to the Xbox One HDMI input.
2. Connect the Xbox One HDMI output to your A/V HDMI input.
3. Connect your A/V HDMI output to the HDMI input on your TV.
4. Notes
   
5. This option requires that all devices support audio over HDMI.
6. Surround sound from your set-top box will not be passed through the Xbox One.
7. When you perform this kind of basic setup with an A/V receiver, you're passing both audio and video through another device. Depending on your equipment, there's a small risk of audio or video lag.
8. Connect your set-top box HDMI output to the Xbox One HDMI input.
9. Connect the Xbox One HDMI output to the HDMI input on your TV.
10. Connect the audio output from the TV to the audio input on the sound bar using either HDMI or optical S/PDIF cables.

There are a couple of options you can use.

Are your DVD and cable actually going to the Onkyo first and then to the TV? I am assuming it is, if you listen to the Onkyo when watching a DVD or cable.

The Onkyo receiver you have has 2 hdmi inputs and 1 hdmi output.

Does your Xbox360 have an hdmi output and that is what you want to connect to the Onkyo? Some do and some don't.

If your Xbox has a hdmi output and you are already using the 2 hdmi inputs on the Onkyo, you can not connect the Xbox using the hdmi, you have no more hdmi to connect to, so you must go thru one of the other inputs of the Onkyo.

The hdmi has the video and audio together, the other video options do not. you would need to run seperate audio cables as well.
Your Xbox should have a composite video (yellow RCA jack) output or a component video (1 red, 1 blue, 1 green RCA jack) output.

When you connect the Xbox thru, lets say the composite video of the Onkyo , you will also need to connect the audio from the Xbox to the Onkyo on the same input. It should be right next to the yellow RCA jack or right under it. They are 2 RCA jacks, one red and one white.

You will then need to connect the composite output of the Onkyo to the composite input of the TV.

When connecting like this, you will also need to select the composite input on your TV with your remote for your TV. Your TV should have an input button that lets you go thru all the different inputs to it.

you can also use the component video from the Xbox if it has that. But you must also run the audio to the Onkyo as well to the corresponding audio inputs of the component video input on the Onkyo.

This may sound a little confusing, but remember that the hdmi has the audio and video in one cable, the other video options do not, so you must run additional cables for the audio to the Onkyo from the Xbox.

Also remember whichever video you use from the Xbox to the Onkyo, you must also run that same video from the Onkyo to the TV and then switch the TV over to that input when you want to watch the Xbox on the TV

why dont u connect the xbox directly to the tv via HDMI cable? the output will be fantastic.The component cables just cannot give a better resolution than HDMI.
As for connections,i am not in favour of component and HDMI together.
