SCART nothing more than a connector. This connector supports several different standards. RGB, Composite, S-video.

The A1200 can natively output two of them; RGB (23-pin video connector) and Composite (Yellow phono socket).

As Jope (and I) said the A1200 cannot output S-Video without being modified, or first going through an (expensive?) converter.

Indicates nothing of the sort :] I know what SCART is, and what it supports, and that the A1200 does not output S-video natively. I *do* have a way of converting it, necessitated due to once being in a situation where I had RGB on one device, and only S-video in on another.

Why? You will never be able to buy this exact monitor. It definately does PAL60 (aka NTSC).

What is "Multiscan"?

alewis · 11 October 2006, 22:41

Right, I have my 2100FP's back. Will set up with an Amiga, both native and Cybergraphics, to the various inputs.

And if I can, will post some LCD pron

An AGA monitor in DEVS... basically 640x480 (can be hacked with montools, I use 656x492) 30-31KHz 60Hz native.
Square pixels, not squashed like PAL res.

Possibly being pedantic.. but PAL60 is not the same as NTSC. It has the same refresh rate/resolution but the colour encoding is entirely different.

alexh · 12 October 2006, 16:46

I know. But AFAIK PAL Amiga's dont do NTSC. If you select a Monitor of NTSC in workbench you get an NTSC resolution 60Hz screen. You dont get NTSC colour encoding.

I have had good experience with my Viewsonic VX922 19 inch LCD. It does 50Hz perfectly, so I'd take it that where Viewsonic claim a monitor can do 50Hz, it can. They are pretty cheap and quite good quality.

Obviously it can't do 15Hz, so you still need a scandoubler at least.

Aye, 'tis true...

Bloody stoopid different screenmodes..

CRTs forever. They're much less harsh, have better color depth and the pixels melt together a little to form pure goodness

If I goto ASDA and buy this monitor, do I need anything else to get going to plug it into my A12oo?

This is 100% true for composite and RF signals.

RGB is colour encoding agnostic, it only provides the red, green, blue and sync. Thus the "NTSC" and "PAL" is in terms of refresh rate and amount of lines on screen only, and there is no encoding really.

Amiga RGB SCART cable. (23-pin Video -> SCART)

killergorilla · 13 October 2006, 14:16

Surely something like this is gonna do the same?

Or am I missing something here...

alexh · 13 October 2006, 14:18

Probably. But it may not accept RGB SCART input (only composite).

The features says that it does have the VGA input so you can use it with AGA and RTG at the same time as a BMON which is cool.

If you are getting one, check for the VGA connector and ask if you can return it if it doesnt work with RGB.

The ASDA dual one is confirmed as RGB capable, confirmed having a VGA input, confirmed as having the ability to switch off the sharpening filter on the scaling.

killergorilla · 13 October 2006, 14:36

Ah too true.. it's no good without RGB.

I'm not after buying one as I don't really use anything other than games on my amiga

this looks ok though:

Sound Output?

If it is SCART and not 9-pin CGA then yeah.

If you want to send the sound through the TV and your cable doesnt have them you'll have to wire in two Phono plugs to the SCART cable. The SCART pinout is available online, it will be just 4 solders.

Personally I use my hi-fi for the sound.

Currently I have an old VGA CRT monitor connected to my desktop A1200 via an external Scandoubler.

Are you telling me that instead of replacing the monitor with a LCD one I should instead buy a small LCD tv with a scandoubler built in and use a scart connection instead?

IFW · 16 October 2006, 21:54

ViewSonic monitors support 50Hz.

I just wanted to share this bit of information.

I was trying to use my A500 with a BARCO video monitor that had a SCART input, but it didn't work. I was puzzled, because the same SCART cable worked fine with my 1084 monitor.

Some time later I tried connecting the Amiga and the monitor through the SCART input of a VCR and from the VCR's composite out to the monitor. But that didn't work either, the VCR wasn't accepting (or converting) the RGB signal.

SCART input on the BARCO worked fine when used with the VCR to watch movies and TV (had to use a VCR because the monitor didn't have a receiver).

It then dawned on me that maybe the VCR was sending a composite signal (as opposed to RGB) through the SCART, that's why it worked.
I verified this by using a Composite to SCART adapter from the VCR to the monitor - picture quality was identical to when using the SCART to SCART lead.

So, how to get the SCART on the BARCO to accept a RGB signal directly?

I called the importer of BARCO in Denmark and talked to a tech there, who explained to me that pin 16 on the SCART (also known as the Fast Blanking pin) needs to be fed a small voltage for the BARCO monitor to switch to RGB mode.

So, I connected a 1.5 volt battery to pin 16 and then the RGB signal from the Amiga 500 worked. Crisp and clear! I never found a more elegant solution for this and eventually I got another monitor:
http://salminen.homepage.dk/ (nice, eh!? It's for sale btw)

So if anyone tried this but got a black screen on their TV/monitor, it's because the Amiga doesn't provide the blanking voltage on the RGB output.
You have to find other means of holding pin 16 high.

Hope this helps someone.
