Is that an Extron DSC HD unit? Yeah, I've noticed some of that too in some of the scaling modes. I've been using a Gefen scaler that doesn't seem to have these problems, though it outputs SDI instead of HDMI (though it's full chroma 444).
I think Danexmurder is referencing an Extron Emotia. My biggest issue with those machines are their age, rarity, and price. They are very old machines and require maintenance. They also use obscure power supplies. If you're good at tinkering and enjoy soldering, that's no problem. For people that just want to play video games, the Emotia is going to be inconvenient and expensive to purchase and own.
I never noticed any issues with the Extron DSC 301 HD scaling engine.
Everything comes out clean for me. I do have one complaint; my DSC 301 HD unit does not tolerate off spec signals (arcade PCBs) or Nintendo sync jitter very well. (But, that's an upscaling use case.) If I recall correctly, other people have experienced the same issues.
The DSC 301 HD allows users to program custom resolutions using an "EDID editor" (although, it's not really EDID, because we are programming the DSC 301 HD to actually output a different signal). Unfortunately, it cannot do low pixel clocks and it will not downscale to 240p. So, the 301 HD not a downscaling option. I realize nobody asked or suggested the DSC 301 HD as a downscaler, but this thread is about downscaling, so it's worth mentioning.
