Remember that if you order a monitor from the EU you will probably need to buy a voltage transformer.

EU = 220v 50Hz AC
US = 110v 60Hz AC

I do not think either Philips or Commodore monitors are dual voltage (but I could be wrong)


 Alexh is right. C= branded monitors are always "mono-voltage". But they will work with a simple voltage transformer.

 Don't need to worry with the frequency difference on the power supply: the internal voltage circuit of monitors can cope nicely with either 50 or 60Hz (switched power supplies).

 The same could be not true for the video input: image don't fill the screen with Amiga in NTSC in a PAL monitor. Or image "over the edges" of the screen with a PAL Amiga using a NTSC monitor.

 Open the monitor and tweak the trim-pots will fix it, of course.
Goodbye people.

I\'ll pop on from time to time, RL is acting up.

Voltage conversion wasn't a problem.  Waiting for a Commodore 1960 in the mail.  Also does my A4000 (new box I picked up (old but new)) not work with the A520 because it's probably got too late a version of kickstart installed? It's trying to output 31kHz horizontal maybe?

Also I'm going to put in another thread this machine, the A4000/040 has a key on the front.  Like a locking key.  And I was able to open the machine up to upgrade it without owning the key but I'm quite worried I don't have a monitor for this thing yet and I don't have this key thing as the seller didn't provide it with the computer.  It turns on and registers there's a HDD there but I'm kinda worried a bit till I can see a display, because seems like none of my floppies really get properly accessed.  Not even sure if this thing works yet.
it\'s too bad she won\'t live, but then again who does?

It should work fine.

If the screen mode in workbench is a 31KHz mode it could be. Hold down both mouse buttons after a reset to enter the early startup menu. That will be in 15KHz.

Big deal.

You should be able to see just by looking at it if it is in the locked position. Just disconnect it inside. If you really must have it connected, the key is a standard key you can get in loads of places. Most modern HDD caddies use a key that will fit.

By the sounds of things, it doesn't work.
