I have seen lots of VGA vs Component for topics for LCD tv's but none for DLP. Has anyone used both on a DLP tv? If so which was better? and why? How was the upscaling with DVD's? Thanks

Personally I think Component would work better on a single chip DLP system then VGA would.

VGA breaks out their colors into the individual elements (red, green and blue) this works well with CRTs which have Red Green and Blue guns as well as LCDs and Plasmas which also have red green and blue elements to display their data.

Single chip DLPs have one chip that creates a black and white image, and from that the color is added with a color wheel. Component video has a black and white image on the Y cable and then the color data is matrixed across the remaining two cables Pb and Pr.

To me it would seem that a component connection is tailored for single chip DLP since it breaks the video data down into chunks that work well to the way single chip DLP systems work.

Of course I could be way off base... and there's a distinct possibility that the way these displays interpret the signal changes from system to system (for instance it could just compile the imagine completely before sending to the chip/color wheel meaning it would depend more on the video interpretation mechanism as opposed to the display output mechanism).

That's just my impression.

Many new (read: expensive) DLP systems don't even have a color wheel. With the older, more common systems, though, I might say "go component". For new systems, though, VGA may be the way to go.

Can we get a bonified expert in here to help? I'm a little confused on this issue as well.

My TV has a color wheel, though it was expensive ($5000) Mitsubishi, go fig, lol. I used it as a monitor for almost a year via the VGA and it was an amazing picture. I am not too worried about the connection being an issue with the color wheel as my TV handles VGA great, my worry is in how the 360 outputs it's signal. I have heard that it looks very washed out on CRT's and LCD's, I am wondering if it is a problem with DLP's. I asume it would be. But I also heard that the problem was cleared up in the last 360 firmware patch, is this true? And how much better is the picture of the VGA cable over component? Thanks for your input.

I have a Samsung 50" DLP with a VGA input and am using the VGA cable, resolution set to 720p. When I switched from the component to VGA I had some friends over, guys went "Holy SHIT!" at the picture improvement.

My Sammy has a 5-color wheel, the newer DLPs are using 5 LED's instead of the wheel. I can't tell the difference and I've got freakishly good eyesight.

I haven't been able to tell the difference in a store setting where I can compare the two side-by-side, but when I'm in a darker room, especially when watching something with a lot of contrast (Underworld, Good Night and Good Luck...etc) I can see a RGB rainbow around the edges of things with a color wheel. Most of the time it is unnoticeable, and the more expensive models have worked around it, or are just plain better at shifting colors.

Some people can see the "rainbow effect," others can't. I cannot, on any DLP. No one has ever mentioned to me that they could see it on my Samsung. However, I can see the "screen door effect" on nearly every LCD projection I've seen.

Heh, and that's funny. I can't see any "screen door" effect on any 1024x768 (or widescreen equivalent) resolution projector on up. It truly proves that people see in different ways

I use a VGA LCD pc monitor for my 360, and it looks fine, no washed out effect, or any other effect.
