Im interested in the 50/60 hz motion on it, if its fully smooth as with a TV.
On a CRT monitor the 50/60Hz modes are synced and perfectly smooth (pinball, etc), but depending on the monitor, 50Hz can sting the eyes after a while. No 100/120Hz modes, at least not on the MKI Indivision 1200 I had. The ribbon cable did negatively affect image quality a little bit.
No problem on the few LCD monitors I have that support 50Hz, with a bit of the usual LCD smearing (better or worse depending on the LCD). Also, you'll likely have to tweak the monitor settings and may or may not get an acceptable image.
For old games and demos, I ended up with a few Sony RGB broadcast monitors, and couldn't be happier.
