The component inputs on most HDTV monitors use the YPrPb color space,
which is different than the RGB colorspace used by a D-sub (VGA)
in/output. The electrical conversion between the two colorspaces
can be done using analog circuitry, but it isn't something as simple as
cutting open a cable and soldering on new connectors. <br><br><div><span class="gmail_quote">On 11/12/05, <b class="gmail_sendername">Steve Adeff</b> <<a href="mailto:adeffs@gmail.com">adeffs@gmail.com</a>> wrote:

<br>><br>> You can tap into the RGB on your vga cable to make a component video cable<br>> (or buy one premade) and it will provide a progressive scan image. I was<br>> reading about this a while back somewhere on avsforums I think.
