AFAIK, yes. It's certainly a LOT better than the RF on my DC in terms of picture
quality. The picture's a lot sharper and the colours are more vibrant.
(Still can't use 60Hz modes, which is puzzling; my TV supports RGB SCART in 50Hz but
chokes on 60Hz?)

It's not impossible for a TV to be able to support RGB but not 60hz I'd have
thought.

It's not impossible, but in practice, there's no such thing. ANY set that
will do RGB (ie any with a SCART socket), will also do 60Hz.

I'd suggest your SCART lead is carrying SVideo and not RGB. Try another one
to be sure.
Does it work in 60Hz mode through the RF socket ?

Yes :)
Since the days of the imported SNES, I've dealt with hundreds of TVs for
people for imports - because either the picture was rolling, or it was
black-and-white. In every single case, we sorted the problem with an RGB
SCART lead. I've never seen a single TV, in the last 15 years (!) that won't
display a 60Hz picture through it's RGB SCART socket.
I have however seen the odd wierd telly that will ONLY display 60Hz through
it's SCART socket (not Composite or RF), and the same with NTSC-colour.
Because of the way RGB bypasses EVERYTHING inside the TV, and goes straight
to the guns, it seems to be a cure-all for any issues that the TV has.
Nom
Agreed, the two things are completely seperate.
I would assume it's either because the RGB signal bypasses the internal's of
the TV, or it's because any TV with a modern-enough tube to accept RGB, will
also be modern enough to sync to 60Hz.

I find that very hard to belive.
I've posted the same statement to some VERY high traffic groups (such as
uk.media.dvd), and nobody's ever questioned it. The odd time that someone
said their telly couldn't do it - it transpired that the TV was displaying
the Composite image from the SCART, instead of the RGB. His particular telly
would ONLY display RGB if it was the only signal - composite seemed to take
preference ! A friend of mine has a v.old Mitsubishi, and it's SCART socket
won't take RGB at all - it's composite only !

composite. I've used this on my brother's TV and got a picture fine, but I
could only run games at 50Hz; 60Hz caused the picture (colour picture,
remember!) to roll.
It's a Ferguson 14-inch. I can't be a lot more specific, it's about 50
miles away now!
Oh, and posting something to uk.media.dvd just means that after an hour
nobody will ever see it again ...

Correct me if I'm wrong, but isn't a DC SCART lead RGB-only? As in no composite or RF
signal at all? Whenever I do the 60Hz test on Dreamcast games with the SCART lead in
place, the picture rolls. If that's not "doesn't work in 60Hz" I don't know what is.

My TV - a piece of low-end Bush crap, not sure about the model number - will NOT
display a 60Hz signal, whether through RF or SCART. I know this due to the
Dreamcast's lack of RF or composite signal when used with a SCART lead, (mine's an
official lead, not a third-party) and the fact that the picture rolls when trying
60Hz through that SCART lead. I've tried SA2, Capcom vs. SNK 1, Soul Calibur, PSO -
the 60Hz tests all have the same results, with or without the SCART lead.

I doubt it. Mine's an official SCART lead. Don't have access to another anyway.

Nope. Can't do 60Hz at all.

There are loads of televisions that support RGB via Scart but do not support 60hz.
My old Sanyo was one of them.
Maybe yours is in the list?

My TV - a Bush 2054T - doesn't even appear on the list it seems. So no clues there.
:/
Col
looks like a small square with rounded edges, inside or breaking through one
of the edges is a symbol.
If it shows a '1' and two arrows <> it's probably composite only, if it has
three raised dots '...' then that is the symbol for RGB.
This logo usually appears on the screen when you first select the scart
channel for a few secs.

What sort of TV do you have, and how old is it ?
Nom
news:2d689e39.02070...@posting.google.com...
Some points :
PAL 60Hz and NTSC 60Hz are not the same - the PAL image has a greater
resolution. The ability to display 60Hz NTSC does not mean it can display
60Hz PAL.
60Hz PAL is not an official standard.
That list makes no mention of RGB capability - 99.99% of the
non-60Hz-capable TVs on that list, won't have a SCART socket, or it won't do
RGB.
Very old TV's had a V-Hold dial, that allowed you to adjust the sync. Modern
TVs do it automatically. 99.9% of TVs that have no adjustable V-Hold, WILL
do it automatically, otherwise, unless your electricity supply was synced
EXACTLY to your TV feed, the picture will roll.
Did you open up your Sanyo to see if it had a V-Hold Pot ? It's 99.99%
likely that it DID, if it genuinely wouldn't sync to a 60Hz image.
It's more liekly that your TV will display a 60Hz NTSC image, than a 60Hz
PAL one.

Since the electricity supply varies a little, that would also cause a bit of
roll.

The automatic V-Hold just obviously didn't have the range to extend to 60Hz.

Okay, rephrase original question; isn't the official DC SCART lead RGB-only?

The TV's a Bush 2054T, as for age I've no idea unfortunately.

difference, but by how much?
I am assuming the RGB signal coming over the SCART produces a progressive
scan image vs. the interlaced SVideo.

You can pass through composite, RGB, and s-video through a SCART lead as
long as it's wired up right (I think - although if that's the case, which
pin passes this signal? I can't work it out....)

RGB is supposedly better though, but I think a lot has to do with your TV I

SVART is not a video standard, it's a cable type. You can send SVideo over a
SCART cable, or you can send RGB. You can send other things too :)
RGB is slightly better than SVideo, but there's not much in it.

No.
Why would it ?
The only way to get a progressive scan image, is to use VGA video - ie get a
VGA box, and connect it to your PC monitor, or get an HDTV.

Which pin ? Um, lots of em ! There's 21 pins in there, and they're all used
for different things. RGB and SVideo share a pin though (can't remember
which one), which is why you can't have RGB and SVideo at the same time.
Your TVs SCART sockets are RGB or SVideo, not both. Your Dreamcast SCART
lead is RGB or Svideo, not both.
Composite is not shared with anything, so usually a composite image travels
down the cable as well as the RGB/SVideo one. There's also provision for
Component video to use a SCART lead - the odd VERY modern TV supports this.

Yeah, I know about the pins, I don't see what you mean by RGB & S-video
sharing a pin though - is the Svideo split out into R, G, B (which are all
carried seperately thru the SCART cable, pins 7, 11, 15 - see link below),
or what? From looking at the pinout descriptions, you can see which pins
are required for RGB, and which for composite, but svideo isn't clear at
all.

Does RGB use a sync pin? Perhaps that's the shared pin between RGB and S-video.

SCART RGB is the best TV picture you can get out of a DC.
When you say SVIDEO do you really mean COMPOSITE (3 phonos)?
Composite AV cables are not so far behind RGB and are a huge improvement on
RF.

RGB uses three pins, Red, Green, and Blue.
SVideo uses two pins, Chroma (Colour), and Luma (Brightness). One of these
two pins is the same as one of the RGB ones - either the Red, the Green, or
the Blue (can't remember which). So you can't send both down the cable at
the same time.
Composite uses a seperate pin (Chroma and Luma), so you can send that down
the cable at the same time as RGB/Svideo.
See ?
Nom
VGA is *VASTLY* superior to SVideo, because it's Progressive, ie
Non-Interlaced. The vertical resultion is doubled.

You can, with a VGA box.

No, VGA is.

No, SVideo is a 5pin mini-DIN, and is VASTLY superior to Composite (1
phono). The sound is the other two phonos, no matter how your picture is
being transfered !

Yes they are.

No, they're barely any improvement.
VGA is best by far. RGB is next, with SVideo a close third.
Composite is complete shite, and RF is worse.

It's Red then. Pin 15 is Red In & Chrominance.

Actually, it seems that pin 20 is Compsite Video In & Luminance. If as you
say S-Video requires both Chrominance (pin 15) and Luminance (pin 20) then
it seems that you can't pass composite & S-Video at the same time either.
Or I'm looking at a crap pinout listing, whichever.

Many HDTV's are coming with pc-like VGA connectors in the back. Mostly the

No, the vertical resolution is the same. But the frame-rate is doubled
making for a vastly superior image.
Interlace uses two *fields* of 240 lines interlaced with each other to
build a 480 line *frame* on your television screen.

Not many.
Most projectors do, and all computer monitors do.
What's your point ?
Nom
You can DEFINATELY pass SVideo and Composite at the same time. IIRC, SVideo
takes it's Luma from the composite feed (pin 20), and it's chroma from a
seperate feed (pin 15). It just "ignores" the chroma on pin 20. Luma and
Chroma = Composite. Pin 20 carries both.

You said that the best TV picture you can get from a DC is VGA, and for

?
Frame rate has no bearing on image-quality.
Your dreamcast outputs the same frame-rate - 60Hz - whether it's in NTSC
mode or VGA mode. It outputs 50Hz in PAL mode.

Exactly my point. At a given moment in time, only 240 lines are displayed on
your TV.
A VGA/Progessive-scan image does NOT do this - in effect the vertical
resultion is doubled.

Irrespective of what the "vast majority" can do, the fact remains that the
best possible image your DC can produce, is VGA.
Every single person on this newsgroup has a VGA-compatible device -
otherwise how can you use your computer to post to this group ?

My computer isn't plugged into a TV.

It's quite simple. You said that the best TV picture you can get out of the
Dreamcast is VGA. This is not true for the vast majority of people. The
best *picture* you can get is a VGA one, but that's not a TV picture. And
it's not feasible for many people.
