S-video (TV) vs CRT VGA display: examples

(1/7) > >>

Gray_Area:
I've seen S-video on some of my own monitors, but was curious whether the effect was similar elsewhere - because I've been confounded when people on here have thought their S-video looked so darn good!

Recently, someone sent me some pictures of their monitor displayed via S-video. Finally, hard evidence! Then I took pictures of the same sequences for contrast. Both monitors shown are 27".

Notice how it looked like the image is inside some fishbowl with pink water.

You are perfectly correct when noticing that s-video will never be as good as a true RGB signal.
Usually the colors are faded, there is bleeding and less contrast and sharpness.
However some TV sets do a pretty good job with s-video too, and it can be playable. But me personally wouldn't do that since the RGB option will kick ass every day IMHO :)

Maybe a comparison between a PC monitor and a TV isn't really fair, but it should still be be easy to see the difference when feeding the same TV with different signals...

bkenobi:
I don't think anyone here has ever said S-video is BETTER than VGA.  I can say that on a decent TV, S-video is noticeably better than RCA.  I can also say that if the monitor supports RGB signals natively, a VGA signal should look much better than S-video.  I have a set that includes RCA, S-video, and component (Y-Pb-Pr).  I've tried all 3 and on my set there is definitely a difference between RCA and S-video, but the difference between S-video and component is negligible.  I believe my set simply down-converts the HD signal down to a SD that's essentially equivalent to S-video.

If you want to know more details, I would think the monitor forum would be a great place to peruse!

Malenko:
are those the same tube? same lighting? same camera?
not a fair comparison.

look at my KI2MAME project, the earlier pix are component , the later are SVideo, there isnt a HUGE difference, especially in MAME

Now I can say that VGA is always gonna look better but to say SVideo looks like crap is an overstatement, its not like we're using composite

The S-Video photos were taken with a flash (which makes the colors appear washed out) and the VGA photos weren't

Here are some S-Video vs RGB (arcade monitor) comparison pics I took a while back (be sure to zoom in)...
