There's a bunch of stuff in the devs:monitors directory but nothing for 1084. That's not unusual is it?
Actually it is very unusual. Why did you copy all that stuff there? The Devs:Monitors directory should be almost empty with only those drivers in it your monitor supports. If you put drivers in there which you monitor does not support, you can even kill the monitor.
If your 1084 is NTSC, then put NTSC into Devs/Monitors, if it is PAL, put PAL into Devs/Monitors. Nothing else. And before you put the CF card into your Amiga run Prefs/ScreenMode in WinUAE and select a screen mode the 1084 supports (either PAL:Highres or NTSC:Highres).
