What's the best way to hook up component? and an audio lag question

Ok, as I was browsing Monoprice looking for my BNC Jack-to-RCA Plug adapters I found another way I could do things and I'm curious what method will get the best signal.

Method 1: Regardless of what I do I'll run my component cables from my devices into a female-female adapter to hook it up to another cable. Method one is to use these

Method 2: Is to use BNC jack-to-RCA plug adapters to turn the BNC plugs into RCA plugs on the projector and then just run this component cable

from the other component cable to the projector.

I have to use the female-to-female adapters regardless because the component cables I use for my game systems hook up to the systems proprietary inputs. It's possible both these methods are equally effective but I figured if one is a better method it's worth finding out which.

My other problem is I'm concerned I'll have audio issues if I use a component cable that's to long since the optical cable running to my reciever is so much shorter (only about 3 feet long), should this be a concern and what's the maximum amount of cable I should consider running?

One last thing, the cables running from my game systems are RG-59 so if I used method 2 would it be pointless to connect them to RG-6 cables?

Note: Btw yes my pj does support component it's just on the same plugs as the RGBS so that's why I need to change the BNC plugs to RCA.

I'm completely lost with what you're asking... as you asking how to hook up a specific component (ie: device) or are you asking about how to hook up something with component outputs to a CRT projector?

What devices are you trying to hook up to what?

What sort of outputs do the devices have?

You do realize that what is traveling through those cables is traveling at near the speed of light. That means if one cable were 50 feet long and the other 1" long you couldn't tell.

Be warned that simply turning component ends (RCA) into BNC ends (funky metal ends) does NOT mean you will get a working signal from your source.

Component is sending a "Y/Pb/Pr" signal. BNC is a "R,G,B,Horizontal Sync,Vertical Sync" signal. Very different.

Sending your computer signal, however, out via VGA-to-BNC breakout cable is the same signal.

The projector accepts a component signal but the component inputs are on the same BNC plugs as the RGB so I need to turn them into RCA to be able to connect my component cables.

I'm talking about component cables dude, specifically coming from a 360, PS3, and Wii that's why I need to hook the proprietary cables for the consoles into a female-female adapter to then plug them into the other component cables or the component/BNC cables since they're not long enough as is and the component inputs on the projector are on the RGB BNC plugs. So more or less what it boils down to is what will give me a better signal: component cables hooked into the BNC plugs with BNC-to-RCA plug adapters or using the component-BNC cable I linked to.

They'd be identical. I can't imagine the human eye could tell the difference.

I agree with that BUT there are a million people on here that would not.

I back this up by stating this:

I made custom RGBHV cables for an installaiton and a highly reguared ISF guy came out and told me that its not a good idea to do that. I use RG59 and pull 5 legnths the same and cut and terminate them. They are all the same length, if any thing there is NO MORE then 1 " differance between all of them but I dont think they even deviate that much.

He said this is not good and that must all be PERFECTLY the same lenght becuase bandwidth between the colors will vary and not make a good pic.

Granted i have hear some things about this guy that make me think he relaly doesnt know his ****. He even wound up blowign up the convergence board during this ISF that he couldnt even do.

Putting BNC connectors on RCA plugs and RCA connectors on BNC plugs is fine and will work just fine.

Ok, just thought I'd check before I proceeded to be safe.

I assume buying the end-adapters is cheaper?

Yes, but it does not make them right.

The Lumagen processors take 54 milliseconds to process. That means, if you are not running audio delay, the video is approximately 1/20th of a second behind the audio and most people cannot see lipsync issues.

Light or electrons are traveling through those cables at approximately 900,000 feet per millisecond. That is 900,000 feet in 1/1000 of a second! It takes 1/100,000th of a second to travel about 900 feet. In my 50 feet vs. 1" example, the difference is 600:1. The means, the 50' long cable would take about 1/150,000th of a second or 1/150th of a millisecond longer than the 1" cable. No one can possibly discern this difference.

All this reminds me of the guys who think their speaker cables can't vary in length at all. LOL.

I hear that Dave.

What about the special little wire elevators to hold speaker wire off the ground 6" you think that is necessary and the sound is effected if it was to run right on the carpet?

LOL

Its just amasing some of the smoke and mirrors in this business.

YOU HAVE GOT TO BE KIDIDNG RIGHT?

If not check this out. I have some property located in COZUMEL Mexico UNDER WATER in one of the best reefes in the world.

But wait theres more. I have a glass house down under water there kind of like the one Homer Simpson had in one of the episodes except mine is real and in one of the best places to have spectacular underwater views.

You have to use ROYAL CRIBBIAN Curises to go there and they let you sail for free!

Im selling this house fairly cheep cause I simply dont use it as much as I could. So your gettign a great deal here folks. An underwater home and basicly a free cruse every tiem you go to your new home.

PM me and Ill give you all the details!
