Passing PC resolution over HDMI via audio receiver

Yes, it works just like any other HDMI source.

Mine (Onkyo 606) seems to pass through whatever I send it (tested with both a GTX 280 and a 4870)... the only catch is that when plugged directly into the receiver, I seem to have none of the NVIDIA scaling options and am locked to "let my device scale" (the rest is grayed out). This makes no sense to me, but just wanted to give you the heads-up.
Thanks for the replies. 
I was looking at a Yamaha 6190B (was practically 50% off during boxing day), which does have a "through" HDMI setting, but it seems to only pass standardized TV resolutions. Or at least, that's all I can select without getting a black screen on PC/360. Not a big deal considering the price and model, and I was more interested in the audio decoding for when I get Blu Ray equipment anyway; I can live with my previous connections.
I like that I can program the buttons and functions from other remotes for other devices that I have. And the auto sound setup thing with the mic is pretty nifty.

Hmmm...it could be that I've never had a problem with it since my TV is a 1080p set. I don't have a 720p TV with native 1360x768 res to test out.
I'd imagine manufacturer's that want to take shortcuts will just hardcode in the regular TV resolutions and leave it at that. That's quite possible.
Would certainly be something interesting to test out if I did HD receiver reviews for a living.

The native resolution of the display doesn't have any barring on what resolutions it will take anyway, just which ones they have to scale.

Sort of. If the TV has a native res of 1360x768, you can normally pass that resolution directly from the PC to the TV at that res.
However, I think the problem AlStrong is having is that when passing it through a receiver he's not getting the option of passing 1360x768. Only the standard 720p resolution. Or at least that's how I'm interpreting what he's saying.
And while TV's do a great job of making the most out of the native resolution for 720p motion video (IE - you really won't notice a difference between a physical 720p set and a set with 1360x768 pixels), for computer use such as displaying a desktop or browser, a non 1:1 mapping is not very nice to look at.

And some 1360x768 TVs don't, while some TVs with other native resolutions will.
Again, the native resolution of the display doesn't have any bering on what resolutions it will take.
I don't see how his comments could be taken to mean anything else.
It depends on the quality of the scaling used. On my 1366x768 plasma a 720p looks very nice, as does 1440x810, which is what I run my desktop at. Native 1366x768 does look slightly better than both, but only slightly, while standard text is a bit overly large at that resolution from my viewing distance, and I like having a bit more desktop space as well.
Yes, that's correct. I guess there is no PC handshake or... what is it called... in the AV receiver just like most HDMI ports on TVs (except for the one port on my TV that allows PC resolution over HDMI). So the 360 only gives the options for regular video resolutions. I was hoping the "Through" option on the receiver, described as 'no scaling' just passing through the signal, would still allow me to use 1360x768.
So as it stands:
360/PC -> receiver -> TV's HDMI PC port= 480i/p 720p 1080i
The main reason I want 1360x768 is because there is no overscanning at all. Even if I use the Just Scan option on my TV for 720p, there is a slight bit of overscan, and I'm very anal about it.
I believe there is no overscan at all with using 1080i (would have to double check), but it introduces a lot of lag... so much that I notice it with regular games, not just Guitar Hero or Rock Band. And of course, using the receiver for HDMI switching also means that I wouldn't need to use the separate dongle for optical out on the 360.

Sure it does. Unlike VGA, devices with an HDMI output (similar to DVI) or using a DVI to HDMI dongle can query the display device for available resolutions. The driver them limits your choices for available resolutions for the display device.
I do however agree that it's quite likely some TVs won't report back that they support 1360x768 and thus you only have the standard 720p option.
And in AlStrong's case. His TV apparently has 1 HDMI interface that will report back support for 1360x768. However, routing though his receiver he doesn't get that option as the receiver only reports back the standard HDTV resolutions.
As to the rest, maybe I just got a bad Aquos with a bad scaler. Because anything other than 1:1 pixel mapping with a desktop introduces all kinds of annoying artifacts and blurring. As was the case with my ATI card over HDMI until I figured out how to force it to do 1:1 mapping. For some reason by default the drivers were overscanning (underscanning, I can remember right now and in Japan so can't test) the output to the TV. Actually thinking about it, it was probably the video cards fault and not the TVs. Meh...

That isn't unlike VGA, VGA can do exactly the same. Furthermore, that does nothing to dispute the fact that native resolution as no bearing on what resolutions a display can support.
And again some some TVs with other native resolutions will take 1360x768.
Do you understand that?

Yes it does if your driver limits you to the resolutions the TV (or receiver) lists as available. Do YOU understand?
Sure there's always 3rd party tools available to force modes that the TV doesn't list but most people don't use those.
Likewise, I'm sure if you tried to force 1080p or 1920x1200 on a 720p set, the display won't exactly work correctly. Sure you can always use a 3rd party app to force it, but if the sets scaler can't handle it... Well it just isn't going to happen.

I understand none of that has anything to do with the number physical pixel elements in each dimension on the display, which is what the phrase "native resolution" refers to.
Then you have mislead yourself.
