You can but only ECS screen modes will work.  like DoubleNTSC/PAL, Multiscan, Productivity but NTSC/PAL will not work.  So early startup, and games will not display.  Some very rare monitors, like the one I mentioned a few posts up, will scan to all 15KHz screen modes!  Try to find one of those.  I think there are some BenQ LCD's that also work, use Google to find out more on this topic.

This is partially incorrect.  If your monitor only syncs to 31KHz screenmodes (i.e., most modern monitors), DoubleNTSC/PAL, Multiscan, and Productivity modes should work.  Or at least are supposed to.    The only problem is you won't be able to see your Workbench to select those modes, since natively it boots up with a 15KHz screenmode.  Also, as TjLazer said, Early Startup and most games, etc., won't work because they use 15KHz screenmodes.

Now Amiga switch on PAL, but I think, you can switch on NTSC in boot menu.

The A4000 has a PAL/NTSC jumper on the board you can either switch the jumper or make a toggle switch.   iirc there are some games that switching in the early startup menu wasn't good enough.

So putting a toggle sw on these two contacts will keep in in PAL or NTSC depending on where you have the switch set? Now that I have changed the startup and have the reboot line in there to accommodate the new libs PAL wont stick in the early startup menu if booting into workbench so this would be a good workaround.
