External scandoubler for 15KHZ RGB Amiga

I'm using this:

VERY nice quality from Amiga RGB (there is also component version)

and this one:

Cheaper and way worst, especially if you want to work on Workbench. For games, both works fine.

BOTH of them seems to by "flicerfixers" so you can easily use DoublePal etc. modes in Workbench.

Kreciu: I have two Amiga Scart cables, one I bought recently the same as the AmigaKit one, but neither works (only a black screen) with the $40 AUD Scart to HDMI converter I also bought on ebay. I have a 4K TV so I decided it was a bit much and have opted for VGA instead.

I got my SCART cable also from Amigakit.com AND on one of my Amiga1200 it does not work. I suspect that my RGB output is bad... (didn't have time to see what is exact problem).

So, it can be your Amiga problem. I assume you have not possibility try another Amiga?

check if you have enough voltage on SCART pin 16 (blanking signal)

I will most likely do the same for this A1200 that have also problem with RGB/SCART cable.

BTW. SCART to HDMI converter is really nice, only thing what is noticeable is a "haze" around mouse pointer (when it is moving).
