Video straight to TV or through Receiver?

OK here is my situation. I have an HD Samsung TV(1080p) and a Onkyo receiver(TX-SR701) with no HDMi inputs.

So currently I have all video and audio running through the Onkyo via component video and optical audio.

Now my picture quality is great but should I connect the cable box and PS3 directly to the TV via component or HMDi? I've heard that component and HMDi is the same picture quality so my real question is would there be a visible improvement by bypassing the receiver and going straight to the TV for my video inputs.

The main disadvantage of this would me the manual input selection via the TV instead of just choosing video 1 or 2 on my receiver.

Thoughts?

Direct connection to the TV has the advantage of being able to view the TV without having to turn on the sound system. Some TVs will look different on the HDMI vs component inputs. Some look better, some worse. Generally if the TV is ISF'ed (calibrated) there will not be much difference and it is possible for the component connections to look better.

OK but is there a downgrade is quality by going through a receiver? I had never really thought about it until I got HD a month ago. Now I strive to get the absolute best picture possible.

There shouldn't be any downgrade, but anytime you insert another device in the signal path there can be that potential.

I think it all depends on the reciever. I had issues with having my connections go through my old Sony reciever - I'd get a scrolling white line going up the screen sometimes. Plugged in direct I'd never see this.

With my Onkyo 805 though, I don't have the issue. I'd bet you'll be fine with the 705.

And if there was an issue, I'm sure it would be noticable without any comparison.

I'm in a similar situation. I'm about to get a new TV (Sharp Aquos LC46D92U) and a new DVD player (haven't decided which one yet), and I want to run the audio through my Reciever. The receiver has surround sound on it, but it's about seven years old, so it doesn't have HDMI.

Can I assume, by this thread, that there would be nothing weird about running video directly from DVD into the TV via HDMI, and running audio cables separately from the DVD to the reciever?

Thx!

If your wanting to take advantage of 1080P you have to use HDMI over component. And I agree if you put anything in between a signal the picture degrades. If it's an option run video seperate.

Explain, please.

. . . more explaination needed here as well . . .

Yea, "theoretically" correct, but rather misleading. Particularly in the context of this thread which is discussing HDMI connection in which case it could be argued that it is not even theoretically correct.
Note: of course the addition of any element (even a short length of cable will theoretically degrade the signal, but it does not logically follow that it will also degrade the picture, as in most cases it will not.

I think this is a distortion of Rick's previous and much more accurate suggestion that "There shouldn't be any downgrade, but anytime you insert another device in the signal path there can be that potential." Note the operative word "potential" - certainly not absolute in any sense in the case of HDMI digital signal.

I have a Samsung DLP with 1080p display. When I connected my STB to the TV via HDMI, and connected the STB to my home theater receiver via digitial coaxial, I could not get 5.1 sound when I had the TV on the HDMI input. The sound would play through my home theater speakers, but only in 2.0 channels. Someone told me that this was because when my TV was on the HDMI input, it was recognizing both the audio and video feeds on the HDMI line, and since my TV only has a left and right speaker, it was overriding the 5.1 channel feed from the digital cable connection between my STB and receiver. I could only overcome this by using the component cable connection and input on the TV. Has anyone ever run into this or know how to overcome it? This could cause me serious problems should I make the leap to a blu-ray or HD-DVD player. It's the Samsung HLR-5078W DLP television.

Since you ask how to overcome this:

If you get a surround receiver that supports HDMI it would solve the problem. Otherwise I don't have a clue.

Probably not the solution you were thinking.
