FWIW, i didn't spot anything out of the ordinary regarding picture quality - but as i said, i've no possibility to compare it to a VA1/2.
Do you maybe have screenshots for comparison and/or to show what to look for?
What model or Brand is your VGA box?
I can try. Keep in mind, the screen that I use for these tests is a 27' ASUS LED monitor (same ones used at major fighting game tournaments).
This all originally came about after having purchased a Kaico brand HDMI Adapter. I haven't been too happy with the latest model of the Pound HDMI Adapter I previously own (the colors don't look right and the overall image looks tad blurry). I kept hearing the Kaico HDMI provided better results and to my surprise, it does. It almost looks on par with the system's native VGA output quality (mind you I've tested other brands of the same product and they are terrible).
When I use the Kaico on all my VAO systems, it produced some faint yet fairly visible vertical lines across the entire screen. But not when I'm using it on some of my VO1 systems. At first I though maybe it was the cable itself (and it could very well be). So I decided to test one of my older generic VGA cables and it produces similar results tho not as profound. Since I do own an Official SEGA VGA box I decided to test that as well, but produces an excellent picture quality across all hardware models.
So... perhaps it's not so much the hardware itself, but how these 3rd party video cables are being designed?
