Hi S0nic :-)

In my experience, an LCD attached to an Amiga is always like a lottery ticket.

Usually  it will not work, because the PAL signal  that comes out the custom  chipset of any Amiga (50Hz) will not sync  any modern LCD (usually around 60Hz). The reason is that historically computers are now attached to a monitor instead of a TV, thus it is cheaper for manufactures to limit the usable range of the monitors to the now standard VGA frequency.

The LCD monitor you want to use must have a proper RGB connection, which is more and more rare these days.

That usually means that you will not be able to play games but only be able to visualize Workbench (provided you have a 23pin adapter-to-VGA and you set a ScreenMode such as PAL, NTSC, DBLPAL, DBLNTSC). Although you are in Europe, if you set NTSC in Workbench you won't break anything, it will simply set a higher frequency ScreenMode that possibly will let you see something on screen (albeit you won't see the lower part of the screen due to the different resolution: PAL is 256 pixels height, NTSC is 200 pixels).

There are notable exceptions: my Dell U2211H, for example, is able to sync anything from 50Hz. That means that I can display output from the custom Amiga chipset, PAL, NTSC and also higher RTG resolutions (through a standard VGA cable).

If you want to use a modern monitor with your Amigas, the other option is buying a Scandoubler/Flickerfixer device: they basically "realign" the video signal. The downside is that these devices are expensive.

A native Commodore monitor is surely the safe way to go and it's the best choice if you like the "retrocomputer" feeling.

Hope this helps.

this is that fixer?

Yes, that's the device I was talking about.

Those from Indivision are the most wanted because they're newly produced and they do both the scandoubler and the flickfixer jobs at once, but they only exist for A1200 and A4000.

I know there's a choice of external SD/FF devices too, but their output quality does not compare well to those of Indivision. While external devices are cheaper, internal devices work better because are physically plugged to the video chip.

In case of A500/A600 there is no internal possibility to plug such a device so the choice is much obliged.

Yes there is

Ouch, you are right, I forgot about the ECS version.
Thanks for pointing me that.
