I've successfully used a Samsung 510T with the PIV SD/FF.
The specs said it works at 56 ~ 75 Hz.
To my surprise it also worked at 50 Hz.
This also goes for my current samsung 206BW monitor.
It happily works at 50 Hz.
Edit: I had to fine-tune the settings though, because the auto-adjust button of the monitor didn't use the optimal settings.
