I have an AV cable that connects Atari 1040STE with a AV to VGA converter. For some reason the vertical edges are not sharp, rather jagged or pixelated. I red that old atari would have an issue with modern display, as refresh rate of 15Hz is not supported. I was under the impression the converter would do the trick, but on the other hand, if I recall correctly refresh rate applies to highest resolution output to vga directly. Can you suggest where to look for a clue on how to fix it? Provided is a photo of the issue. Also included the components I used, maybe I went the wrong path. Perhaps any electronics inside is to blame and needs checking? Any feedback welcome as this is my first step in retrocomputing.
