Hi Walter,
It can handle all NTSC and PAL modes with 15.60 or 15.72 kHz.
The highest I can see is:
PAL Super High Res Laced - 1280 x 512 @ 15.60 kHz with no flickeringBy
adjusting the overscan I can set it to 1372 x 548
Since that's wider than 1366 of the panel it must be shrinking it down
slightly, but it looks very nice.

Subject: [torontocbm] Re: Commodore Amiga 520 Video Adapter Some followup.
Still playing with the Sole monitor. I reconnected the Amiga 1200HD and sure
enough I had it set to VGA output, which did not work on the SCART connection.
Hooking up commodore's vga adapter and a cable to the Sole gave me a picture.
By adjusting the screen prefs I determined that the VGA supports signals
approximately 24 kHz and up (which is typical). So to support all Amiga
1200/4000 screenmodes you'd have to make a custom cable that connected both
SCART and VGA. Of course if your main reason to use the 1200 is for games then
the 15kHz SCART RGB should be fine. I also verified that the SCART
connection also supports S-Video, giving a pretty good picture. Steve

Subject: [torontocbm] Re: Commodore Amiga 520 Video Adapter Hi, I just
received my SCART to HDMI converter today. I also found my SCART cables. Ya! I
did a little quick testing. First I tried connecting up to my Polaroid TV
with scart. I knew this TV was not the highest quality, but it's on my desk and
has every imaginable input on the back so it's handy to have while
experimenting. Unfortunately I got no picture at all with the converter. I
removed the converter and verified that it was working with SCART directly into
the TV and that worked fine (with C64). I tried the C128 but for some reason
it's not powering on. I don't know if it's the power supply or the computer. It
was actually working earlier today when I was testing the scart cable and
worked fine in 80 column mode, but not in 40-column mode. I suspect the SCART
cable is not wired for 40 column. There were several versions of SCART cables
and I guess I got the wrong one. Will need to pull out another C128 and power
supply... Anyway, moving to the other side of the room is my main computer
with DELL 22" HDMI monitor. Hooking up the C64 through the scart converter to
the monitor hdmi was finicky but eventually I got it to work. Next I moved on
to my Amiga 500... success again! Amiga 1200HD... no go. It boots and I can see
a screen colour change on the monitor, and some streaks, but no workbench. It's
been a while, but perhaps I have the preferences set to some weird video mode.
I will need to pull out a real 1084 or 1950 to check what's going on.
Anyway, I verified that the SCART to HDMI supports composite and RGB. Hopefully
I can sort out the other issues and complete my testing. If anyone wants me to
test a particular setup let me know. Steve

Subject: [torontocbm] Re: Commodore Amiga 520 Video Adapter 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. Steve

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.

Video Adapter 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 ;-) Steve PS: Yes, I'm crazy...

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 From:

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"
