And we don't have it in aus either but that didn't stop me buying an Amiga to scart cable and the scart to hdmi converter.

you really don't need those
if a monitor have HDMI input means that will accept 15hz amiga modes through VGA input
 because those monitors have internal circuitry that do the same that the adapter scart to hdmi
so you will need only a normal Amiga VGA adapter+ a monitor with HDMI input

examples:

Dell U2410
Samsung  syncMaster 2493HM
BenQ G2420

Most monitors and TV's outside of Europe dont support 15khz RGB modes because they dont support scart - the only screen I have that can handle 15khz via VGA is my 50" Pioneer professional Plasma Monitor in my lounge room.

If your monitor supports 15khz modes you only need an Amiga to VGA adapter (amigakit sells them) and a normal VGA cable.

My Samsung monitor supports 15khz modes but only at 60hz and my miggies are all 50hz models.

the vga adapter must work on your monitor...you can try it first you buy another expensive adapter
on amikit they sell those for 15 or 20 u$ I do not remember very well
also you need a vga cable of course

it's not related if the monitor is euro or if support scart...is related to the monitor capabilities
The 3 monitors I listed above are not for the euro zone but guaranteed that support all amiga models through vga adapter
what I calculated is that if a monitor have HDMI input+vga ...there are 90% of chance that a normal vga adapter will works
of course I can't guarantee that all monitors will work...but the HDMI presence is the green flag to try

Ok I got my SCART-HDMI adapter today and initial impressions are very good - I've had it connected to my Samsung 22" LCD Monitor via both HDMI and DVI-D to test out the TV Modes and PC modes using my a1200 running ClassicWB Full with an AmigaKit DB23-SCART Cable.

I've found 720p@50hz via HDMI to be the best compromise so far as my screen isnt native 1080p. There is a very subtle softening effect around the moving mouse cursor and when things appear on screen in WorkBench (might be my Samsung LCD but im not sure yet) but this is not noticeable during during the 1/2 dozen demo's i've tried. Also of note in 720p@50hz, all scrolling is perfectly smooth. :)

The colour from this unit is absolutely superb, the best i've seen from a converter - I did have to turn down the brightness on my screen till the "black" border vanished (was a bit grey), but once I did this I was very impressed with the black levels and colour reproduction. The gradients are perfectly smooth too, firing up AGA tweaked Dopus reveals perfect colour transitions and no banding at all!

Oh and I fired up RSCP (Drive speed test) which gave the VGA converter a hard time and the SCART-HDMI converter easily and almost instantly shifted to the high-res laced mode with no fuss at all revealing a pin sharp display and no wobbly images. :)

Fine patterns, like the one in the WHDLoad "loading" window are also rendered extremely well. Another item of note is that it will convert 50hz to 60hz in the PC modes and scrolling smoothness, while not perfect as in the 50hz modes, is still decent considering.

Im prolly not going to have the time to take some pics for a few days with my prosumer camera so sorry about that, I quickly tried my iPhone 4s but it washes out the Red's and makes them look orange so just doesnt do the image justice.

One problem I have encountered (not the adapters fault) is my 19" Mitsi LCD seems to have a broken DVI-D port which is most annoying - at first I thought my HDMI-DVI-D cable might be faulty but it worked fine on my Samsung LCD. I cant even force the blasted screen to manually switch to DVI-D in the OSD, it just falls back to VGA each time. very frustrating as this is my Amiga Screen! :(

-------------------------------------------------------------------------------------------------

I also found some time to plug the SCART-HDMI Adapter and a500 into my 32" Sony Bravia using HDMI and the results are great - just a superb picture!!! :)

I find myself using the 1024x768@60 mode tho because my TV annoyingly wont let me squash a 720p or 1080p picture into 4:3 ratio!

That said I've been playing SWIV and BombJack on my 32" TV and having a blast!!! :D

The only issue I've found is with my AmigaKit RGB-SCART cable, the left and right channels are swapped around (confirmed with my multimeter) - so other than needing to swap the RCA's over, the sound conversion is excellent thru the SCART-HDMI adapter! :cool:

@ djos : where did you buy your scart-hdmi adapter ?
do you have a link ?

if I want my 1200 on my TVLCD, I have to go through my DVD player/recorder to get a picture (through scart). My Panasonic TV, although it has scart input does not recognize the signal coming from my 1200.

It also converts composite and s-video using a cheap scart plug adapter.

Btw mine came with a travel adaptor and the PSU is multi voltage. Also considering it is only $10aud dearer than a gbs8220 and is in a metal case I think it's very good value.

Ok I found the problem, on all my screens that support HDCP over DVI-D the SCART-HDMI adapter works perfectly via DVI-D or HDMI and my only screen that doesnt support HDCP is the Mitsi and as a result the SCART-HDMI adapter doesnt work.

So before buying a second hand LCD Screen for your miggy, make sure the specs say it supports HDCP over DVI-D (most modern screens do these days).
