Amigas and VGA

  • Follow


Hi all,
     I've just obtained an Amiga 500 and I'm wondering if anybody has 
had any experience with connecting Amigas to standard VGA monitors, any 
help is greatly appreciated.
Thanx

Aside of the fact that it is probably better to be asked on 
comp.sys.amiga.tech or comp.sys.amiga.hardware - yes. You need a 
ScanDoubler or FlickerFixer hardware add-on to be able to see all the 
Amiga graphic modes on the VGA monitor. Those were also available for 
A500. Also (AFAIR) if you have a relatively late model with the latest 
Denise chip inside, and you have upgraded the software to 3.1 ROMs you 
should be able to get a very limited (in terms speed and number of 
colours) MultiScan mode, which shows up on on the VGA displays. Of 
course to set this up you need to see something first. If your hardware 
consists of plain A500 plus VGA monitor - you need the hardware add-on.

All you need is an external flixker fixer/ scan doubler as the on epower
computing supplied me years ago.

Hi,
   You need two things to make the setup work. First it's an RGB to
VGA adapter. These pop from time to time on Ebay. The other thing is a
VGA Multisynch monitor able to go down to 15 KHz.

Sure, it is possible.

1) 23-pin to 15 pin Amiga/SVGA adaptor
   and a slow scan monitor (15khz!)

a quick search turned this up:
http://www.kme.co.uk/CRT%20Desktop%20Monitors.htm

Please note the UK source (electric differences and such for US)

2) a scan doubler module

I think #2 is the cheaper option (still a bit pricey) but you don't need any
special monitors.

        Hope this helps,
                Dan

I wonder if that small, metal adapter box that came with the Amiga
4000s for converting its display connector to a SVGA would work on an
A500? You might also need Amiga Workbench 3.0.

To be able to use the A4000 silver adaptor, you need your Amiga to output a
videosignal, that the VGA monitor can display (ie. using a DblPAL, DblNTSC
or Multiscan monitor driver. The adaptor itself doesn't convert the signal
in any way, only the monitorplug from 23 -> 15 pins.

I can't remember if you need ECS or AGA chipset and which Workbench version
you need...

You would probably be best off with an external scandoubler/flickerfixer. I
don't have any idea where you can get one these days though... :-(

Best regards,
Jacob

I use the RGB:VGA box that came with my 1200, they're quite common, IIRC 
they actually shipped with the 4000.  Any Amiga accessories vendor should 
be able to hook you up with one.  

But the restriction is that you have to find a VGA monitor that will handle 
a horizontal sync down to 15 Khz. Those are quite rare.  Someone needs to 
develop a box that adapts the hsync to 31 (?) or whatever it is on the 
normal PC.

There are plans on Aminet for an adapter that you can use to go Amiga->VGA, 
but the same sync restriction applies.  I built one for my 500, and it 
works great on my 1942.

S.o.D.

I recall there being a revision "-1" and a "-3" where the "-3" could
be used with any SVGA monitor. Back in the day, I was using my Amiga
4000 with an NEC 3FGx SVGA monitor with the "-3" and had no problems
even though the monitor didn't support 15 KHz.

The Amiga hardware newsgroup is the best bet for an answer:
comp.sys.amiga.hardware
