New HTPC - No Video

post #1 of 25
Thread Starter 
I just finished building this HTPC..


ASUS P5Q-EM LGA 775 Intel G45 HDMI Micro ATX Intel Motherboard - Retail


SAMSUNG 22X DVD Burner Black SATA Model SH-S223F - OEM


G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model F2-8500CL6D-4GBNQ - Retail


Intel Core 2 Duo E8400 Wolfdale 3.0GHz LGA 775 65W Dual-Core Processor Model BX80570E8400 - Retail


Antec Black Aluminum / Steel Fusion Remote Black Micro ATX Media Center / HTPC Case - Retail


Western Digital Caviar Black WD6401AALS 640GB 7200 RPM SATA 3.0Gb/s Hard Drive - OEM

I also added an 80 gb SATA drive and loaded Windows Vista 64 on it. I hooked it up to a 1080P tv at my beach house (where I built it) and it works fine. At home I have a 1080i tv. I have a Denon 2809 I hook it up to via HDMI, and it is output to my tv via component. Audio is there, as I hear the Windows boot screen, but I get no Video. I thought maybe it would be a resolution issue, but I can't even see the boot screen. Any ideas what's going on here?

Try bypassing the Denon at home and get everything working then try the Denon again.
I suspect that the Denon is not outputting the 1080i HDMI video input in 1080i resolution over its component output If your 1080i CRT TV has a button on it's remote that says what it is receiving try it to see what the Denon is sending to it over component.
Hopefully there are setting options in the Denon that will enable you to correct the problem.

I have bypassed the Denon and it works fine. The panny plasma acts as if its not receiving anything... anyone else with a Denon having this issue?

Have you changed the PC output resolution to 1080i or 720P instead of 1080P? Your Denon probably doesn't accept 1080P signals.

I thought it auto detected it? I just plugged into a 24" monitor and the resolution was set to 600*800? I then unplugged the monitor and back into tv and still no picture..

Don't know about autodetecting. 800x600 is a PC resolution, does your TV and the Denon accept PC resolutions?

I assume so.. I changed it to 1080 and it still didn't recognize it. It won't recognize any resolution. I'm not sure why it changed to 600*800. It wasn't set to that when I turned the pc off before.

800x600 is the default resolution of graphics chips untill told differntly by the OS controlling the chip after the OS or other controlling software boots or takes control of the chip.

Any idea how to resolve this?

Time to get out the Denon manual and see if it will output a HDMI signal over component. Could be a HDCP issue trying to do that.

Most receivers won't go from HDMI > Component, they will go/upscale in the other direction however. You're asking the receiver to convert the purely digital signal to an analog one-not very common at all.

Oh boy, I thought component and HDMI were equal, except HDMI carried audio too. So if I run an HDMI to my tv it'll work fine? If so, how long of an HDMI cable can I run before the signal starts to deteriorate? I need to run about 15-18'.

Hi,
I had the same issue as you but via a Denon 1909. I eventually got video/Audio over HDMI by changing the value in the registry. The value was BitBashingSupport and I changed it to FF.

This has been mentioned over on the DG45ID Thread however I don't know if it is the same for the Asus board.

I still don't have video on BIOS post but video works once the vista drivers have loaded

Regards

I run 60' in my home for HDMI, so I don't think that 18' should pose any problem at all

Thanks Kipster, I'll give that a shot.

Thanks Rocky.

After looking at Denon's website, this is the first question in the FAQ section...

http://denon.custhelp.com/cgi-bin/de...i=&p_topview=1

I don't fully understand what they're saying, does anyone else? I was under the impression DVI or component was a high def connection. I have only a hand full of options that I can send to the AVR... I have a ATI 4850 I can hook up that has dual DVI outputs or I can use onboard graphics and that has HDMI and the standard pc outputs.

Well, I've figured out the problem so I'll post the resolution for anyone else that may have this problem in the future. Due to HDCP, signals from HDMI or DVI cannot be broadcast over analog cables such as component or s-video. That's the way I understand it anyway. So I'm off to yank out 20' of component cable from within my wall and replace it with HDMI. Problem solved.
post #18 of 25
Just for kicks (and I'm sure you were going to do this anyway) test the cable before yanking the old and running the new...

Component can often deliver the same quality picture that HDMI can (although it's not allowed to pass 1080p in the U.S.). However, component is very different from HDMI. HDMI is digital, and component is analog. HDMI is basically DVI + audio and is definitely not component + audio. Can you not connect an HDMI cable from the receiver to the TV?

20 feet or less should be fine for an HDMI cable.

component can deliver the same resolution quality that HDMI can.
However, due to the fact component is analog and not digital the color quality can be slightly dergraded if the the chip used to convert the digital TV signal to analog color and the chip in a digital technology TV to convert the analog color back to digital color are not a good match for each other.
Broadcast interfaces such as VGA, Component and S-video can support HDCP. Only handshaking protocols such as DVI or HDMI can.
Your problem appeas to be a Denon problem since you can't get it to convert 1080i digital HDMI to 1080i analog component.
Very few digital sources today require HDCP. I understand that in 2012 the studios will start requiring on BR DVDs and at that time if you do not have a digital ouput with HDCP the signal will be downscaled to SD and output over component.
What happens if you run 1080i over component to the Denon?
post #21 of 25
Have you considered running component from your HTPC to the TV and spdif/optical sound to your Denon? Or even using the hdmi to the Denon for audio only (not sure itf this would work but worth a try.....)?

That's where my confusion came in. My PQ is just as good as any I've ever seen.

I can, the problem is my panel is above my fireplace, which is gonna be a !@#$! to plumb, but it's got to happen so... I'm still trying to figure out the best way to do that. I could just run it out my roof and down my chimney and straight into the back of the tv

I have considered it, the problem is the exposed wire.

The only outputs I have on the HTPC is DVI and HDMI. I'm not sure how I'd change that to component or how it would react if i could? Also, how would I specify 1080i output in the video card? I only see the option to change it to 1080, 720, etc?
post #25 of 25
When you see the options for 720 and 1080 does it not say if the 1080 is 1080i or 1080p? Most likely it is 1080i.
Your 4850 card should also support HDTV-Out (which is the alias for YPrPB component) most likely using a dongel. If it does then you have a way to send component to the Denon.
