After a long prototyping, testing and validating process, we finally have a perfectly working product without needs for calibration. Secret is that we designed around a gaming console video converter IC. This IC has been around for a long time now and has a perfect, noise free output. It works with both 240p and 480i NTSC formats. It can also work with PAL 50Hz formats. No color bleeding on vertical edges nor flickering in interlaced mode. It’s even better that the original thing on a CRT! My workbench screen of my Amiga 2000 is crisp and bright!
If everything goes well, it’s going into full production by Q4 2017.
