Having had this monitor since day one (think 1986) I can tell you that it will work BUT it does not work too well. You will have to fiddle with the vertical adjustment and size and when you do that, it messes up the NTSC adjustment. So it does not auto switch the modes like the newer 1984(S)-P monitors do. The boxy 1084(S)-P's work beautifully for switching from PAL to NTSC, but some of the newer 1984's (1984S D1/2) do not.
