Denon AVR-1705 upconversion problem

Squintz: I have a Denon AVR-2802 (an older version of the model above yours). I too thought that I had this problem when I first got the receiver. Where did you see that it said it would upconvert? I'm not sure that it does. In my case, the monitor output will only output the same connection type. No up or down conversion. If I input composite, it will only output via composite, and so on... If this is true with my receiver, I'm pretty sure it's true with yours. You can workaround by running three separate outputs (composite, S-video and component) from the receiver to the projector. In my case, I opted not to run any video through the receiver - Audio only. Fewer cables and no signal degradation. Of course, I don't get Denon's on-screen menus, but I don't care.

Disregard my previous post. I see the upconversion function mentioned on page 13 of the owner's manual. Take a look at page 27 of the manual. Looks like there are some menu items for setting video input mode.
Do you have both S-Video Monitor Out and component monitor out connected? S-video Monitor Out has priority when up-converting, so if you have both connected... nothing outputs.
Also, my AVR-3803 has setup menus with video input/output options where you can assign which video input has priority on monitor out. But it's defaulted to auto-detect so it shouldn't matter unless you have multiple inputs on the same label, i.e., composite, S-Video, and component DVD input all plugged in.

In the display settings of my ATI card it has 4 differnt images. 2 say monitor, one says TV, and one says YPbPr.
I was wondering if i can use the YPbPr and feed it into my Receiver and feed that into my projector. Does the YPbPr output 480p or higher. Can i set that up as a second monitor and a duplicate of my existing monitor like i am able to do with the TV out. I am asking you all because i dont want to go running all the wires only to find out that the P in PbPr doesnt mean that its progressive.
Belowe is a huge picture of what i am talking about.

OK then Squintz, I assume you have a progressive scan DVD player, as you are getting a signal when you input using a component cable from DVD>Receiver>Projector and your projector only supports 480p and not 480i (this is what I gathered from posts so far).
Your receiver will only be upconverting to 480i as you rightfully assumed in your last post. This is because both composite and S-Video are 480i, it is then just seperating the signals (the term up-converting is not technically accurate in this context, as up-converting would mean actually increasing the number of lines making it either 480p, 720p or 1080i).
So technically:
S-video>component, it is separating the C signal into Cb and Cr.
Composite>component, Y/C separation then as before C signal to Cb and Cr.
If you want to know more about Y/C separation, read my post on "S-Video vs AV".
Basically, you will never get a Y Pb Pr output which is 480p (Progressive Signal), only a Y Cb Cr output which is 480i (Component Signal) from S-Video or composite video through your "upconverting" receiver.
Use the Y Pb Pr output from your ATI card and you should have no problems, it will probably default out at 480p.
I have a question though, you say your projector supports 1080i, does it do this through component, ie Y Pb Pr?
It may do this through DVI if you have that input, but if it does it through component, your graphics card may support this (I can help you with the settings at a later date), and when you play HD media such as WM9 you will get amazing results!
If you want to know more just ask!
(I may be a little late with my responses as I'm currently living in Shanghai, so I'm pretty much only awake when you're asleep)

Wow! your really starting to dig deep into the old post :blink:
I got this issue sorted out. I ended up buying an adapter with selectable outputs for my ATI card. Works very well except for one small limitation. When i setup my ATI card to display my desktop on the monitor 2 output i can not view videos on the second monitor(projector) Only the primary monitor can display videos. This is a software limitation or driver limitation. I forget which but i don't think its within my control. So im gonna have to wait another year and ask santa to bring me a Dedicated HTPC for my theater. Hopefully something like MCE. Santa just doesnt have the money for it this year

I once noted something similar when trying to output to a second monitor from my laptop, couldn't watch video or play full-screen games.
In my case, this could be quite easily sorted out:
Just needed to press FN+F7 a second time and only display to the second monitor, it seemed it could only display graphics on 1 monitor at a time.
Knowing this, you might be able to sort this out doing something along the lines with what I did.
You may have tried this already, so I don't know if it's relevant. Thought it might be worth a shot though.
