I have been looking for a ATARI ST/E to buy and they almost always sells
with a monitor. But monitors are heavy and therefore the shipping is
expensive, now I wonder can you connect a PC monitor to the ATARI and
still get high resoultion?

Yes you can, you will need an ST-VGA adaptor and you will only be able to
use High resolution.
Several Atari outlets stock them, the first one that comes to mind is Atari
Workshop http://www.atari-workshop.co.uk or check with you usual Atari
supplier.

I think you can use a ST-high res with a small adapter with a normal PC
monitor, if you want med or low then you will either need a scan converter
box or a multisync monitor which supports 15khz scanrates.

Yes, it is possible to connect an Atari ST(e) to a PC VGA monitor. For use in
color, I use an old piece of Atari hardware called Video Key. It connects to
the ST and has a composite-video out port on it. I just connect that to a
video converter and from there to a PC monitor. It works fine for low and med
res, but for high res there is a simple adaptor that plugs right into the ST
that goes directly to the PC monitor. That works great also.

As others have said yes, you can get hi-res fairly easily.. However if you
want to play games then a CRT based PC monitor is no good on its own. What
you really need is something that runs TV type Video, preferably via RGB.
You can then get (or make) an Atari Video to "scart" lead. I use an Phillips
CM8833, but there are several other monitors available. I guess something
like this

not sure to wacth the response .......

Other options are are an external TV RGB to VGA converter, but these seem
both rare and expensive.You can also use a video capture device to route the
video through a PC. Whilst these work, you don't always get a goos
picture....

Hope this helps,

Dave.

Here's some instructions from a well known Atarian (lightly edited) on
how to make a cable. It is also possible to purchase these from
several sources as has been previously noted.

Atari ST to VGA adapter
-----------------------
Claes Holmerup

You can use an SVGA monitor with an adapter cable (which is rather easy

to assemble) to get a monochrome picture. Some old VGA monitors may
work,
but all SVGA should work as far as I know.

Here's how you make your adapter:

Atari (13-pin DIN) SVGA (15-pin HD D-type)
------------------ -----------------------
11 (Monochrome output) 1,2,3 (Red, Green, Blue inputs)**
12 (Vertical sync) 14 (Vertical sync)
9 (Horizontal sync) 13 (Horizontal sync)
13 (Ground) 4,5,6,7,8,10,11 (Various grounds)
4 (Monochrome detect) short to ground (pin 13 on ST)


The trick here is that the monochrome signal is fed to all the inputs
on
the SVGA-monitor, which gives you a very nice monochrome picture. Even
though the monitor in fact is a color monitor, you won't be able to see

a color picture because of the construction of the computer (and the
monitor). If you get your hands on a monitor which handles frequencies
down to 15kHz, it's a whole new deal - then you should be able to build

yourself a cable with a switch between mono and color (a little more
complicated, involving a 4-way switch, but possible all the same). Just

about no modern monitors go lower than 30kHz, so in most cases there is

no other choice than mono - but since most useful programs (IMHO) run
in
monochrome, it's the best alternative anyway...

Good luck!
Claes

**Editor's Note: The ST output is a bit higher than the 0.7V expected
by the VGA monitor, so some sets of instructions call for an inline 4K7
resistor. If your monitor can handle 1V input (most modern ones can),
the resistor is not needed.

Buy an LCD television with a VGA input on it (most have them). Then with a
little switch box you can toggle between low+med (scart) and high (vga).

But otherwise, high-res is all you will actually be getting on a PC monitor.
All you need is a cable which is wired up appropriately. The mono signal
from the ST goes straight to the VGA RGB lines.
