I think you will need a scan-doubler if you want to use that monitor with an Amiga. Vertical 55-75 Hz will not show PAL at all as that requires 50Hz, but will show NTSC at 60Hz.
Horizontal 30-82 KHz is indeed "multisync" but does not go down far enough to 15.60 KHz (PAL) or 15.72 KHz (NTSC). So either of these will need to be scan-doubled. PAL/NTSC interlaced modes are still at 15.60/15.72 KHz. Doubled screenmodes are also (mostly) not above the 30 KHz minimum of that monitor.
It's a VGA compatible display.
