Does the receiver change the image?

Hi, I purchased an Onkyo TX-SR602 Receiver. It has component inputs and outputs.

What I am trying to find out is if it changes the video or could possibly keep me from acheiving 480p, 720p or 1080i. I have looked in the specs. I just didn' t know if it changed the image or not. Thanks for any guidance here or recommendations for a receiver. I got it for $299 open box, so I could not research, but I can return.

Something someone told me: It is 50MHz. It was said that 720p and 1080i only needed 37MHz, and this factor meant it should work.

That is the bandwidth spec for the video switching. You can always bypass the receiver and hook the component video straight to the TV unless the TV does not have enough inputs. It is better to not have a receiver in the signal path unless you just have to.

It is 50Mhz. From what I was reading somewhere 37Mhz is what is needed for 720p. Then someone said it should be 3x that.

Your reply does not match my quote. What are you saying?

Maybe this will help: http://members.aol.com/ajaynejr/whyten.htm

like i said, the best would be not to hook up through the receiver.

Now I want to ask...I have a Denon receiver (about 1 year old - cost about $1,000) I don't know the model off hand. It claims to upconvert the video to make a better image. Do receivers really do this in relation to HD or is that more for regular digital cable?

Many of the better A/V receivers will upconvert SD signals (composite or s-video) to HD format, either 720p or 1080i, so that the A/V receiver can be the central switching device in your system. This feature was added in the A/V receivers primarily to support front projectors so you could run a single set of component cables from the A/V receiver to the projector and handle all of the video types you may have. They could be used in this manner for any TV as well, although I prefer to bypass the A/V receiver if possible.
