Might be worth also discussing scalers there, yes. Would of course be highly interested to see if he likes the Kramer unit.
I think the wrong assumption here is that a device has to be specifically designed for the OSSC to be the ideal companion for it. Many TVs have basically perfect compatibility with the OSSC and I very much doubt that’s the result of intentionally engineering it to be that way. There very well might be a video processor that just happens to be tolerant to all of the resolutions and refresh rates we need and has no other flaws like high processing lag.
