Component versus VGA, and the winner is ?

Archived from groups: alt.tv.tech.hdtv (More info?)

My tv can accept VGA or component video from my Samsung DTV receiver. I
know that this might cause a controversy, but which will yield the best
picture ? TV is Loewe. It is for my bedroom and I only need 1 input.
Current set up in family room is VGA in for DTV and RGB for DVD player.
My thanks for the advice.

VGA and YPbPr are both considered analog "component video".

In the PC world, the VGA component-video connector is dominate. VGA operates
in the RGB colorspace, and is biased towards PC resolutions and timings,
including but not limited to SVGA and XGA. The VESA organization
(http://www.vesa.org) is responsible for VGA and its evolution.

In the CE world, the YPbPr component-video connector is dominate, and the
video format of most broadcast and professional physical-media A/V content
is coded in a luminance/chrominance colorspace rather than RGB. It obviously
operates in the YPbPr colorspace, and is biased towards CE and DTV
resolutions and timings, including but not limited to 480i, 480p, 720p and
1080i. SMPTE, EIA and CEA are largely responsible for YPbPr and its
evolution.

While many display/projector vendors have created VGA or YPbPr (3 RCA jack)
inputs that can support both PC-RGB and CE-YPbPr content, you are generally
best off connecting PC oriented source devices using VGA and CE oriented
devices using YPbPr.

In the digital connector world, the same PC vs. CE split exists, with DVI
being PC-oriented and HDMI coming in distinct PC and CE flavors. Crossing
between the two works, but there are known issues.

They are two very different things.

Curmudgeon - if you feel you know the answer, then why not be useful in this
forum and post an educational and informative post.

Rick,

Thanks for the feedback. HP is taking its first deep dive into CE/DE (vs.
PC) devices, and a few of us are getting to deal with the PC vs. CE/DE
cracks first hand :-( I figure we're all in this mess together. As an fyi -
HP now has proposals before 3 industry standards bodies to clean up some of
the PC and CE/DE variances with some of the analog and digital connectors.
