I just bought a second hand Sony multiscan 300 sf, and because of the name "multiscan" I wondered if I could connect a 15khz rgb signal to it. But am I now mixing up multiscan with multisync?
Regards,
Eyso

hm, I guess so: http://www.computer-dictionary-online.org/multisync.htm?q=multisync

How so? :-?
Well, I see it is able to do RGB, (which is scart; RGBHV is vga)

Scanning Frequency Horizontal: 30-86 kHz
Alas, no 15 kHz there.... But it's a pretty good monitor if you have a scandoubler or an A3000

Yes I saw that, but since in my first link states that multisync is equal to mutliscan, maybe there's a scandoubler in the monitor itself :-)
Btw. it's not only Amiga I want to plug on it, also a Dreamcast and an Atari Jaguar.
but, hum, I can't blow things up if I'm wrong, can I? :nervous:

How are you even going to plug the Jaguar in, much less get it to output 30kHz? :crazy: (Dreamcast will work for supported games with VGA adapter).

Negative.... What the multisync (or multiscan, whichever you prefer) means is that it can sync to any signal within the region specified. In other words, anything from 30 to 86khz will be displayable. 15khz will decidedly NOT be displayable.
Pretty much all monitors sold nowadays are "multisync" (meaning that they can sync to anything within their given frequency range). I don't think anyone has built a fixed sync monitor in at least 10 years or so. Very few monitors can go down to the 15khz range, though.

Ok, since I was about to make my own thread asking for monitor advice, but saw this one, I'll ask here.
I've done some google searches for the Sony CPD-G500 21" trinitron monitor and found no details on the refresh rates it supports. (Other than top end)
Does anybody know if this monitor will support 15khz?

As far as I could find out, all Sony Trinitron screens start at 30kHz, so that's a no go as well...
So: does anyone know any common multisync monitor that'll do 15kHz? (I'm looking for one of those myself as well) Or is it better (cheaper) to buy a scandoubler?
-

No, definitely not. I have a SONY MultiscanG200 monitor, which is perfect for VGA screens, but when it comes to AMiGA native Pal modes, it goes "Out of scan range". I have solved this problem with a CV3D-scandoubler module, which is very handy in old apps (non-DOS, won't use the DblPal screenmodes).
You have to transform the 15KHz signal to 31KHz.
-
Thank you guys for your usefull replies :-)
Pity I can't find a cheap solution to connect scart to vga.
Ah well..

@ McVenco
Microvitec makes the only currently availalbe 15KHz monitor that I'm aware of. Unfortunately, it's geared towards hospitals, researchers, and scientists with bulk purchasing power. If I'm remembering correctly, they quoted me a price of around $1000 US for a single unit.
-
The older MultiSync/MultiScans did go down to 15khz. Among them, Sony CDP1302, CDP1303, NEC MultiSync II, Mitsubishi AUM1381, that I am aware of and have tested. There was actually a NOS Mitsubishi AUM1381 on EBay a couple weeks ago. These are hard to get. Just keep your eye open on EBay.
-
I used to have a Mitsubishi AUM-1381 back in 1989. It was a pretty decent monitor that worked with normal 15khz amiga output as well as my microway flicker fixer.
I look for them on ebay once in awhile, but find the same guy trying to peddle these things for ludicrous amounts of money.

Hm, I guess this one (http://www.hificables.co.uk/ProductDetails/mcs/productID/11100/) can do the job, yet it's not really cheap :-/

If you want to plug a SCART plug straight into a monitor go for the Amiga branded Microvitec 1438, 1538 or 1764.
The only disadvantage being that PAL:Hi Res Laced will flicker - not so if you had any old PC monitor that could go to 30Khz and you got yourself a Scandoubler/Flicker Fixer.
What would be cool is an adaptor/hack so that Amiga scandoubler/FFs could be used by all home consoles such as Jaguar/Sega/Nintendo. All you'd need to do I suppose is connect the console's RGB pins to the RGB input on the scandoubler.
The Dreamcast has it's own dedicated VGA box but not all games work with it.
An LCD TV is another option but, as I have just written on another thread, the Samsung SyncMaster 710MP I just bought is a bit crap.
:-(

Exactly what (standard Amiga) screenmodes can the 1438 display? I bought one this week off the internet for a meree 30 Euro, but I'm only able to collect it at the end of this month. Does it also have a standard RGB connector or do I need some converter to hook it up to the A1200?

Every Amiga mode. If Amiga badged, it should come with 23pin RGB plug.

According to the pictures he sent me, it's badged Amiga. He used it with an A1200, so I shouldn't be scared it doesn't work then :-)

That's a good deal!
As far as I can understand the Microvitec 1438 can display ALL Amiga modes as it can sync down to 15Khz horizontal refresh.
The 1438, 1538 and 1764 had a cable coming out the back which attached directly to the Amiga's video port utilising RGB signals. The 1701 wasn't Amiga badged and had a VGA plug but was still Amiga 15Khz compatible if I remember correct.
You won't need a converter but do remember that screenmodes that are interlaced will still flicker like they would on a TV. This is because the image is made up of two seperate interchanging meshes of pixels to form a higher resolution screen. I think this was used because the chipset wasn't powerful enough to handle 640x512 in one field... could be wrong. I know 640x480 in Multiscan:Productivity mode is not interlaced but is dead sluggish.
You might need a set of speakers too as I'm not sure if all 1438/1538 had integrated speakers. If you get PC speakers be sure to get a small 2xphono-3.5mm adaptor.
I don't have a 1438 etc. so can't say for sure what connectors it has... there is one on eBay being used on an A4000/PIV setup which is odd as the PIV had a VGA connector. Maybe someone can clear this up.
