Connecting PC's VGA to TV's Component

[i am a hobo]

Hello,

I've been reading that in order to connect the VGA from a computer to the component inputs on a TV,
you would have to use a "vga to component converter box"



the other route would be to use a cable, and use it straight from the computer to the TV,
a vga to component cable.

but in order to do that, you would have to see first if your computer's video card can output component, and see whether your HDTV's input is RGB or YPbPr

How do I go about finding out if my computer's video card can output RGB or YPbPr

and

if my HDTV's component input is RGB or YPbPr ?



I'm doing this because I only want an analog signal, without any lag.
I think there's the DVI to Component route, but that's partially digital.



Thank You

Component video is always YPbPr or YCbCr, never RGB. Very few graphics cards output component over the DB15 (VGA) connector. You can be 99 percent certain your computer can't do it.

I'm in the market for a new graphics card

What should I look for if i want to accomplish this feat ?

Formally RGB an YPbPr are component interfaces, RGB to YPbPr should be not a problem.

[i am a hobo]

i looked in my tv's manual, and it says that the component is Y Pb Pr


newegg has a couple vga to component cables,
but all of them say:

NOTE: Specific TV-out feature on video card is required, please check with your video card output specification for compatibility Premium 3 ft VGA to RCA Component cable for your monitor / projector Connects PC / laptop to LCD projector, HDTV, DVD Players with VGA to RCA support, and other Y / Pr / Pb component RGB display system NOTE: Your display system must support component video (Y, Pr, Pb) signal output function in order for the image to display properly. Please consult with your VGA cards user manual for more information.

My video card's manual doesn't say anything about TV-out,

So i either need to get a video card with tv-out or a video card with actual component connections on it, for a direct connection to the TV.


the vga to component adapters are like 80 to over 100 dollars, plus i think there would be some lag since it needs to convert the signal.

80 - 100$ for this sound bit expensive (3 to 6 fast OPAMP's)

Those circuits will NOT introduce any lag or latency (delay) - propagation time will be bellow 50nS.

[jagabo]

Simple circuits like that require that the RGB signal conform to component timing standards (720p59.94, 1080i29.97). The ~$100 devices sold as RGB to component converters will also convert from standard VGA timing and resolutions to standard component timing and resolutions. They can, for example, convert 1024x768 72 Hz VGA to 1280x720 59.94 Hz component. They contain an A/D capture device, frame buffer, and DAC for output. Not just a few op amps.

Yes but they provide low quality for video format change - if nowadays almost any card can be set to correct video format then this provide higher quality and no latency and it is much cheaper than typical cheap video format converters (most of them have 6 bit ADC/DAC integrated with noisy digital electronics and effective resolution is way bellow 6 bits - im talking about those popular single LSI solutions).

There are only a small number of video cards available with HDTV/component out. They are primarily used for home theater PCs. They would only be an option if you don't need a video card with the ability to handle high settings in modern video games.

VGA to component converters may work, but it is likely that not all VGA output resolutions will be supported. Reports on picture quality generally varies for all of them that I have seen. Here is an example of a VGA to component converter with a VGA passthrough for no lag:
http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10114&cs_id=1011407&p_id=...t=1#largeimage

However, note the VGA input resolutions it supports.

It is similar to the Calrad Electronics 40-480 VGA to Component Video Converter available for a much higher price at Newegg.

nice, that's exactly what i'm in the market for

how high do you think the resolution would be ?

my hdtv can only do up to 1080i




thanks for all the info guys

Here are some examples of video cards with HDTV out via the round mini-Din port:

The component adapter isn't shown in the pictures for the example video cards above, so you might have to order one. This looks like what you need for them, but I would check with VisionTek before ordering.

Or you can use powerstrip http://entechtaiwan.com/util/ps.shtm ( very useful program for graphics cards ) to change the timings and resolution.

i used it with 3 graphic cards that naturally didn't support component out and it worked ( i don't have them anymore).

[i am a hobo]

sorry i didn't get back to this thread until now


as far as quality and lag


would a round mini-din port be the same thing as using a video card with actual component outputs (the 3 red, green, and blue connections)

or would there be a slight difference


I'm still looking for a video card that allows for a direct component connection

[i am a hobo]

powerstrip


are you saying it can compensate for lag, so there's no lag ?

[jagabo]

A card with a 7 (or more) pin mini-din connector may support component video. A pigtail adapter is usually used to convert to female RCA connectors. There's no standard for pinouts on those connectors so be sure to get the right adapter.

I don't think I've ever seen a card with 3 RCA connectors for component video.

powerstrip... are you saying it can compensate for lag, so there's no lag ?

He's suggesting using powerstrip to set the graphics card to standard a component video resolution and timing so that a simple RGB-to-component circuit (like suggested in post 6) will work. In that case there would be no lag.

There are no current video cards that can supply component output without using an adapter of some sort. Even years ago, I can't remember seeing any that had RCA component ports on the backplane instead of a breakout cable or dongle.

Analog is slowly fading away. Video cards with the ability to output component video are few in number. Even video cards that provide VGA without a DVI-I to VGA adapter are less common now than they used to be. If you want a video card that has the ability to output component video, buy something while you still can.

I have confirmed that the video cards in my previous post do not come with a component adapter. The one that jagabo linked to is back in stock and comes with a component adapter.

I have one. Its not recent though. Its the ati pci-e hd all in wonder. Its got a rca component output riser card for the pci slot (note that its not on the video card itself it is an adapter that fits on a pci slot that connects internally to the video card) I don't know why I still have it installed taking up a pci slot as I don't use it at all. I should probably remove it and pick up a usb 3 card and use that.....

[pandy]

Based on info from madshi (author for madVR renderer - http://forum.doom9.org/showthread.php?p=1604480#post1604480 ) - empty file named YCbCr located in madVR folder will turn ON YCbCr (YPbPr) on RGB output - this mean that any card with RGB output from now can be used as YPbPr source. Sync combiner (or card that produce so called Sync on Green) + valid video mode timing (nowadays typical HD video modes are predefined or can be easily added to list of available video modes) are required to work.

[jagabo]

empty file named YCbCr located in madVR folder will turn ON YCbCr (YPbPr)

So then you just need a simple D15 to component RCA adapter cable?

More or less but yes - issue is that for YPbPr sync must be on Y (combined Y with sync pulses) - but this is quite straightforward when compared to RGB to YPbPr conversion.

Like these ?
Is the picture quality the same if one were to use these compared to using just component cables from a video card that has a direct component output, which is really hard to find, as i haven't found any


Is there lag since it's an adapter ?



As for these:

What would i need from a video card to get this working on my Y Pb Pr CRT HDTV ?




A converter like this:

Will there be any lag ?



and


HDMI ?

would "powerstrip" be able to take away the lag induced from using HDMI ?

The component pigtail adapters look similar to the one pictured, but the number of pins in the mini-DIN vairies and the assignment of the various component video connections to the pins varies. You MUST obtain an adapter that is pinned correctly for the card, or it will not work as intended.

There is no lag introduced by the pigtail adapters. There are no electronics inside. They are really just cables.

Unless you love tinkering with settings on software like powerstrip or madVR, and the thought of building your own custom electronics intrigues you, this cable is NOT a solution you want to investigate further.

Will there be any lag ?

There will be some lag on the component out connection. The VGA out connection is a passthough, so there is no lag there. If you need no lag on the component connection, this is won't be of use to you.

and


HDMI ?

What do you mean by "lag induced from using HDMI"? So far HDMI has not been part of this discussion. Do you mean lag from an HDMI to component converter like this? http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10114&cs_id=1011410&p_id=...seq=1&format=1

If conversion from RGB to YPbPr is performed without rescaling then any converter should provide latency(lag) free conversion.

We have already covered this. Commercially available VGA to component converters scale, among other things.

As usual your advice in this thread is impractical for the vast majority of Video Help members. Nobody without an electronics background is going to build their own converter. If the OP is asking the kinds of questions he has, he doesn't have the right background to build one. If he has to hire somebody else do the work for him, then a new video card will be considerably less expensive.

First - seems that you don't understand what i've wrote, however if you need to say something then prove it (i can provide you data about HDMI receivers that perform conversion from HDMI to YPbPr/RGB without resizing and thus they are virtually latency (lag) free converters)

The above appeared to have been commenting on my post, since yours was the next after mine and there is nothing to indicate you were replying to another post, or no post at all. The entire thread has been about various sorts of VGA converters and finding a way to have component out from video cards.

My post was primarily about a commercial VGA to component converter that the OP asked about, plus questions about what he meant by "lag induced from using HDMI".

This post of yours was about building VGA to component converters that do not scale:https://forum.videohelp.com/threads/351181-Connecting-PC-s-VGA-to-TV-s-Component?p=2202...=1#post2202696

You created the misunderstanding, if there is one. If you want to be understood, at least make the tiny effort required to let us know what kind of converter(s) you mean and which post you are replying to.

If you haven't learned that 99.99% of the worlds population falls into the category of having no electronics background then you've spent your entire life living in an electronics lab. So everybody in that very large group who is not willing to learn to build their own electronics is lazy, eh? Talk about an ego problem...

One more thing... The OP uses American spelling for a number of words that are spelled differently elsewhere, so chances are he is one of us.

Sorry if i haven't mentioned it, but my tv has an HDMI input

Like I said in my first post,
My goal was to have an analog only signal, as not to have any sort of lag

This is meant so there's no delay when playing games


I was wondering if powerstrip could fix that ?

eg.
Guitar Hero or maybe it's Rock Band, that has a lag compensation
It allows for exact or better timing when there's input lag, and i think also processor lag on the TV
