Tv as monitor. S-video vs RGB?

TorS wrote on 3/17/2004, 11:58 PM
I've just been re-reading that great monitor thread of last year, and I don't want to open up the pro monitor vs standard tv discussion again. I am looking for a standard TV (about 20-21 inches) to use for monitoring Vegas work. Some of the candidates have what they call RGB in the SCART connection and some (few) also has S-video separately.
I know I can get a plug that will accept the S-video cable from the camera and plug in to a scart connector on a TV. But is that as good as a true S-video input?

(The TV with s-video has better price but poorer picture than the two sets with RGB I'm looking at.)

My opinion, with a standard tv I don't think it matters a whole lot. With a good monitor ,yes it does. I am using the composite feed on a standard tv and the final results when viewed on the big tube are almost identical except for a small loss in color saturation which I make up for anyway . My problem is the sound, a small background hiss or
inaudable siren not heard on the computer sound card is suddenly heard in all its glory on the bigg boomer system.

RGB Scart or just Scart?

An S-video connector can only cary S-Video.
A SCART connector can accept any or all of the following (and which of
these is supported on a particular TV's connector(s) depends on what
the manufacturer has chosen to implement):

* Composite video
* S-Video
* RGB
* Component

A SCART connector has so many pins on it specifically so it can
handle all of these standards.

Some European models carry three SCART ports on the back. At least one of these can accept all of the above
(ie you can connect S-Video, component, RGB, whatever to it), and the
other two can take everything except component.

In short, there is no reason to avoid buying a TV with SCART connectors because if you want to connect an S-Video device to it check the owner's manual for the inputs that the SCART port(s) support.

What if the SCART supports RGB but not S-Video? Will an S-Video to SCART plug help in any way? (The camera has S-Video out but not RGB.)

I would suggest a smaller external monitor/TV. The larger the screen size the more the electron beams get deflected and the more distortion you can get especially towards the ends of the screen.

Not a big deal for watching TV, but to use to check how you video looks, and to adjust off of it only compounds the problem and also make convergence more difficult and less accurate the further you get to the edges. Plus there is a loss in brightness the larger your picture tube is. Then the price factor. All in all, I would get a small TV or monitor. I used just a little 14 inch which produces a very bright, sharp easy to adjust and calibrate picture.

In addition to what BB said, I think a smaller screen would also be better if you are viewing it at the same distance as you would your computer monitor(s). My 14" external monitor sits in the same viewing plane as my two 18" LCD computer screens; at a viewing distance of about 30 inches it seems quite adequate in size.

BillyBoy and JL,
Are you saying that the possible degradation I might get from a 21" compared to a 14" screen is greater than the loss of signal accuracy I might suffer from having to dump the S-Video connection and rely on a composite signal? You see, I have not seen a 14" TV with S-Video.

TorS, there are few 14" with SVid, for close viewing, a large monitor isn't as desirable unless you are going into the very high end such as the Sony 20L. I'd recommend smaller as well.

I guess its kind of a apples and oranges thing. While you get a sharper and purer better saturated picture with a "S-video" connection, that issue is GETTING the signal to the TV/monitor. Obviously a "S" video is better than a composite signal would be.

I was referring to is what happens once the signal is processed by the TV/monitor or distorion you can't get away from. Its just a personal prefernce but I rather have a less distored image, meaning mimial convergence issues which are increased as the picture tube size gets larger and have nothing to do with the quality of original signal as oppsed to accepting a minor bit of misconvergence and having a stronger signal.

Have you considered a LCD or Plasma? Then you can have your cake and eat it too. Save me a slice. :-)

================
The differences in what you are considering in this topic will not be visible on a 14" screen. That's why it's hard to find a 14"TV with S-Video. If you are getting a larger screen you "might" see a difference in terms of input types.
The TV's electronics will play a much more significant role than the type of inputs.
