Do DVI to Component adapters work?

[deWaardt]

Hi all.

 

I acquired a late model CRT some time ago. The image is great, very sharp for what I'm used to in a CRT.

 

It supports input over composite, component and S-Video and SCART, and accepts PAL, NTSC, interlaced and progressive video.

Using a DVD player over SCART, and found that NTSC progressive video looks the best. Nice sharp and colorful image.

 

 

Now I was looking for a way to watch Netflix, YouTube and possibly use emulators on the TV.

This made me think about connecting my PC to my TV.

 

My PC has a GTX 950, which has a DVI-I dual link and a DVD-D dual link connector.

I heard about those DVI to component adapters. My question is, do these things really work or is this another chinese scam bullcrap that looks like it could work but is just fake?

 

(Please, for the love of god, know the difference between composite and component)

 

Thanks in advance,

deWaardt

DVI-I to SCART is what you will want since it is Analogue RGB to Analogue RGB, so no expensive adapters required.

DVI-to-Component converters are basically DVI-to-VGA (using DVI-A pinout in the plug) then VGA-to-Component in one unit, since VGA & Component are both (Analogue) RGB signals.

Woa, didn't even know these things exist. I'll look for them.

 

I was referring to an adapter like this:

So this could work?

Looking at that pic, if it shows the DVI side of the converter at minimum it'll be using the DVI-A pinout (sometimes DVI-to-VGA converters use the full DVI-I pinout even if the extra pins are just 'filler') and pumping RGB over the RCA plugs, and be basically the same as a DVI-to-VGA converter plug.

 

Here's a DVI-to-VGA converter that uses the full DVI-I pinout even if it's internally wired as DVI-A (and it only costs like $5 AUD +S&H);

Some googling later and I found a picture of the DVI end of the adapter:

 

That's a DVI-I connector for sure, could be DVI-A on the inside.

 

So this would be analogue to analogue and could work in theory I think (don't have the best understanding about this).

 

Although it's Dutch (I'm sorry) this is one of the things available for cheap over here:

(Gonna have to admit the plugs look a little dogy)

 

I tried looking for a DVI to SCART cable, but I could only find VGA to SCART cables.

I don't have a VGA port on my graphics card, and as far as my knowledge goes VGA is only compatible with composite. I don't want composite.

That will not work, that isn't RGB it is "Luma-based analogue".  That adapter may with some specialised devices, but that will not work for most cases. 

 

Get SCART to VGA then a VGA to DVI-I, if you cannot find a straight SCART to DVI-I adapter.

If his screen is Component RCA, then it'll likely be https://en.wikipedia.org/wiki/YPbPr anyway which is what that plug posted looks to be designed for.

Yea it's YPbPr, it shows it on the back.
