I measured the input latency using a time sleuth connected through the Retrotink 4k. It came out to a combined total of 3.8ms, so I overestimated.
Latency is FAR higher however if the monitor is made to do the scaling by connecting something other than a 1920p source. More like 40ms.
The PVM obviously does accept video input through the option slot. That's what the slot is for. Theoretically, it should be possible to design a board that can interface with the slot and send RGB video directly into the PVM instead of requiring an external cable to one of the other inputs?
I would definitely buy such a board if someone made one.
I've never been able to find anything that does size properly, but the RGB 203rxi does h and v position well. Provided you aren't using an interlaced signal.
One thing to keep in mind is that ao486 doesn't output real VGA signals. Everything goes through the scaler and digitally scales to a fixed output resolution. A clunky workaround exists. I think there's a guide somewhere on this forum.
Yes, in theory that should work. I've got one of those Microvitec multisync monitors (though mine is in pretty terrible shape) and it can sync to almost everything the mister does. I haven't tried using it in a couple years now, though.
I wish those monitors weren't so impossibly rare.
The FXPAK Pro flash cart has this now: https://sd2snes.de/blog/archives/1261
I wonder if any of the lessons learned in that project can be applied here.
Oh, interesting. I see.
This is exactly the reason it doesn't work.
