Support NeoGAF

[KarishBHR]

Ok, so after years of having the same projector and receiver, thinking they werent HDTV compatible, I see that there are component inputs on the projector, and outputs on the reciever. I plug in HD cords to the out, and then the same ones into the projectors in, switch to component input mode and nothing. I tried it with just a DVD player that has HD, nothing... I dont know why this is happening, maybe there is some major thing Im missing.

The projector is a Marantz VP8000
The reciever is a Denon AVR330

Are you hooking it up: RECIEVER->PROJECTOR ? Or DVDPLAYER->RECIEVER->PROJECTOR ?

Take the Reviever out of the equation, there is no point in having it connected until you know it's working (the dvdplayer passing the signal to the projector).

Try putting the dvdplayer into non progressive mode, then into prog. That will tell you if your projector supports whatever signal the dvd player is sending.

If you just hook up the reciever to the projector, you will get no signal, as the reciever isn't going to go and make one up for you, it's just a passthru switch.

A look at your projector reveals that it can do 720p and 1080i, but is LCD is 800x600 so it's not 'true' high def. Otherwise it would be 1280x720.

its still better then what I have now, which is s-video mixed with RCA

 

[Burger]

Sure. Definatley give it a 720p signal if you can. You need to describe the problem a bit better before I can offer any more advise however.

Ok, so I got the DVD Player to work... I went to setup/output/ and switched to component.

The only thing is the reciever, Im thinking that maybe to have HDTV output it needs HDTV input, likes it smart... if the input is s-video, the output is the same, exc.

Does that make sense, or is there an actual solution

PS. What exactly does a DVD player in component do for me

 

[Burger]

OK, thats good news. Make sure you put the DVD player into progressive mode if possible.

Your reciever will almost certainly not convert a S-Video input into a component output. Most are just switches, enabling multiple inputs and one output. If you give it a HD signal it will output a HD signal, the reciever doesn't care. Think of it like railway tracks, lots of tracks merging into one. The reciever isn't going to change a train track into a monorail, if that makes sense.

Having your DVD player run in component will let you use progressive scan for starters, you cannot use a progressive signal over say, composite or S-Video. Plus you'll get a better picture quality. Component will compress the 3 color values (R,G,B) into 3 seperate signals (Y,Pr,Pb). S-Video will compress into Luminance and Chrominance (worse quality) and composite compresses it further into something I forget. Google can help if you are interested.

Ok dude, youve been a HUGE help. Thanks sooo much

I plugged the xbox in with hd cables, then put everything on HD, and it did some weird thing where there were two pictures being displayed. Anyway, I called the projector people, he said I had component in, but not HD... hd signals would only be recognized through a VGA In cord. I need something that will convert Components to VGA, just at the very end, right before the final connection... not component in cords that have a VGA out

Here is exactly what I need:

HD15 to RGBHV Breakout Cable (female BNC)

Its 28 bux at a site I found, I trust that GAFERs can get me it cheaper

Bad news.

A VGA signal is made up of Red, Green and Blue signals, with Sync on Green.

A Component signal is made up of 3 signals (Y, Pr, Pb), but it's not the same as RGB. Here is a good explanation:

The first channel is luminance, (notated Y, the standard abbreviation for intensity). The luminance is the signal’s brightness information only, and includes no colour data. The Y signal by itself gives a black and white picture. The other two channels are called colour difference. They’re notated R-Y and B-Y, and are the difference between red and the luminance and the difference between blue and the luminance, respectively. The colour difference channels can be algebraically recombined with the luminance to give a full colour picture, without having to transmit the green data that, on most video, takes up more bandwidth than the other two colours put together (on average, green is 59% of a video signal).

So to convert a component signal to a VGA signal, you need to do alot of maths, very very fast. Good converters cost a bucketload of cash. You could get a decent VGA box for your Xbox, but I couldn't comment on what quality signal you will get.

Thats not going to work, the signal has to be converted to VGA, which this cable will NOT do.

Wait, what... the guy said this is what I need

so what does what I bought do for me?

That cable is fine if say, your computer monitor accepts a VGA signal over BNC terminals, as opposed to a HD15 plug.

However, your Xbox/DVDPlayer/Whatever, will not output a VGA signal, it will output a COMPONENT signal. It's not the same thing.

If you went and brought that cable, it's useless. If you want a progressive scan signal you will have to buy a converter, but be prepared to spend over US $200

 

[KarishBHR]

Is this What you're talking about?

 

[Burger]

Yes, but keep in mind that it will only work with a PROGRESSIVE INPUT.

The device you linked to will do the color space conversion, but it's not an upscaler. So if you didn't have the Xbox/DVD Player in progressive mode, you would get no picture.

gotcha, so then... when I turn on my xbox, I wont see a thing until the hd game has loaded?

What about NonHD channels on cable?

Explain!

Klee, Burger or anyone that can assist:

I have a Sony VPL-CS5 data SVGA projector that i want to connect to a receiver (Pioneer VSX-D811S) to achieve a decent home theater experience.

I chose to connect the DVD player (component), Cable (S-video), etc. directly to the receiver and have connected the projector to the receiver via one of these cables (VGA cable on one end and RCA component cable on the other):

http://www.ramelectronics.net/html/hdtv-cables.html#hd15rgb

For some reason, I am not getting any picture. I made sure all the connections were secure, but still no pic. Does it have something to do with the projector not being HD? If that is in fact the case, what can i do? I'm a total newb - please help!

Any help would be greatly appreciated!
