Hi,

> A native 60Hz TV runs at 60Hz (or 60/1.001Hz).

Yes, apparently some do. But most display controllers I've seen for LCD panels 
were capable of operating to timings that produce 50Hz, 48Hz, 25, and so on 
lower vertical refresh rates. I thought only a 60Hz interlaced CRT would only 
run at 60Hz (or the mains frequency for some units) and nothing else. But I 
recently bought and returned a small monitor that was 30/60/120Hz only, or at 
least only indicated as such via EDID/DDC.

That wouldn't be surprising, but I'm comparing the result of the same 
processing just switching between a 120Hz timing and 60Hz timing. I think it's 
because my laptop is not doing it fast enough to reach 60fps though.

Regards,
Ted Park
