Got a RARE 1081 and 1084S-P here in this 50 Hz RGB country.
Both support very well 50 and 60 Hz modes on the fly.
The 1081 is far supperior to the 1084S-P (even if they look like 2 twins).
But I got B&W when I put my Toshiba HDDVD player (composite out) on the 1081 with HDDVD(60Hz so NTSC...) and color with PAL DVD (50 Hz)...
Both well setted, I don't see crop like a tweaked "MonoFrequency" monitor.
