It was, but at 70Hz, not 60Hz. 60Hz drops the horizontal refresh to below 31Khz.

And that explains the mild stuttering I see.

If my numbers are right, that’s 640x400 @ 60Hz, which is definitely not vga standard. If that's the case, then I'd expect when I run a game the MiSTer tries to output a native 320x200 signal which is below the monitor's minimum 15khz, which is why I need to set Low-Res to 4x in the menus. This brings it up to the same 640x400 which my monitor is a...

Well, I have vga_scaler=0 set in my MiSTer.ini. I do have direct_video off (0), but I'm using the VGA port on the I/O board, not the hdmi port, and the direct_video setting is supposed to be for HDMI? vga_scaler=0 and forced_scandoubler=0 as well. At any rate, my monitor is reporting 26.94 khz right now, and it looks like this: IMG_0115.jpeg (https...

It's not integer scaling specific, that is a specific type of scaling that will shrink down to 1:1 or 1:x resolution displayed, that might make the image look better, though shrunk. the core only fully functions when video is output through the general scaler at a fixed resolution. It's not really and Interface IO issue, it's that the MiSTer video...

I have a Microvitec Desk Scan 1501 (15VD4DLS2), which syncs to everything between 15 and 64khz, and it works with this core without the scaler turned on. I do have to set Low-Res to 4x in the MiSTer menus or games lose sync for some unknown and probably bugged reason, but once that's set everything seems to look correct. No scaling artifacts and be...
