For a good display you should select the best output from your device. From
lowest to highest quality:
RF, composite, s-video, component, rgb, vga, dvi, displayport, hdmi.    (the 
last few are roughly equivalent)
So, RGB is the highest quality signal available on the Amiga. RGB via Scart is
pretty much the same. A very limited number of VGA monitors can handle RGB at
15kHz, but most VGA monitors only handle 30kHz or higher.
I seem to have misplaced my scart cables, but when I find them I will do some
testing and take some pics. I have Amiga, AtariST and C128 scart cables. C128
RGB is digital (actually RGBI or CGA) so it needs a bit of conversion first.

Duh; of course! Forgot about the main issue, the RGB  Thanks!

520 Video Adapter
Well, like i mentioned earlier, scart is a connector that supports multiple
inputs and outputs; composite, s-video (y/c), component, and rgb as well as
audio in/out. There are also additional control signals for things like
selecting screen aspect and even overlays. Not every scart tv supports all
features though. Anyway, what is useful for Amiga people is the RGB input,
which supports the 15kHz scanning frequency that the Amiga uses. In north
america scart is uncommon, so most people the only option to connect an amiga
to an lcd is to use composite video, which is low quality ( plus the Amiga 500
only outputs monochrome composite, thus the need for the 520 adapter) or use a
scan-doubler to convert the 15kHz to 30kHz for output to a vga monitor. A
scart-capable tv eliminates the need for the scan-doubler.

Yeah, it's obviously passive but cheaper than most cables I've seen.   I'm
obviously missing something; for displaying a SCART signal what makes your TV
worth $100 more than that adapter and an Svideo cable feeding a regular $75 TV?

I have a couple of those. They allow you to either feed composite video into a
scart port or get composite out. Since scart supports composite already, this
is just a passive adapter.

It's an 18.5" widescreen tv from for USD$50 and comes with a SCART input. For
those looking for an amiga monitor this should work nicely via scart. it also
has all the normal video inputs, like composite, component, hdmi and vga. The
only thing it needs is a stand.  Oh, don't bother with the "best offer option"
as it will auto-decline anything below $48. With shipping and money conversion
it'll be about $120 CAD (plus import fees maybe).
I'll give a report on how it works when mine arrives ;-)

Hi, I ended up finding a A520 on EBay for $15 so I thought that was not bad
until he charged me $33 shipping. So yes I would still be interested in the
write up. Hopefully it will stop me from wasting anymore money.

  Yes, I have tested my ntsc Amiga 1200 with a scart cable and it worked fine.
SCART wasn't really known here but the technology is pretty standard. The SCART
cable was just one giant all-in-one connector for composite, s-video, and RGB
analog, along with stereo audio. The Amiga and the old consoles use RGB analog
at 15kHz. Really, you don't need the SCART cable... you could just solder an
Amiga DB-23 cable directly to the SCART-to-HDMI adapter.   Steve

  Hi Steve, can you give me a link to which SCART to HDMI adapter on eBay
would be the correct one to buy. Also would a scart cable work on a NTSC
Amiga?

For about $40 you can get a SCART to HDMI adapter on ebay that works on
the Amiga, assuming you have a nice big HDMI-capable tv. That's gonna get you
the best quality.   Scart to HDMI Video Converter Running with Amiga 1200

    I have one on order to try. You will need an amiga to SCART cable (about
$20) or you could wire up your own cable if you have a db-23 connector. This
adapter also works on quite a number of old consoles like Dreamcast, Genesis,
playstation etc, and should even work for C128 (which I plan to test as well)
and MAYBE even the PET ;-)   Steve       From: "Miraglia, Walter"

  Kipper2k has an rgb2svideo on his site and he is in Canada.  35 bucks.

  Hi Frank, EBay is hit & miss. Either I miss a good deal or they want
crazy money. There must be someone in this group that has  an extra they could
part with.
