I want to know how a scandoubler works with an A4000. I have a CyberVision64/3D GFX card with an Arxon Scandoubler fitted in the video slot. Amiga recognises the scandoubler at once, or I need some software for it? I can see there is also a VGA output so to work this I need something like a Switcher right? Any help will appreciated. Thanks.

I have an Arxon Scandoubler, lovely devices.

Quite simply, plug in a monitor and off it goes, I use a Diamondview 31khz. No driver needed.  The Arxon Scandoubler uses the 4000's Graphics slot.

But not all PC monitors support 31khz.

playing games on the PC monitor is a nice touch. (Even though they only run 15khz).

So, the only way to test if the scandoubler working, is to insert a game disk (OCS/ECS/AGA) into the A4000 and switch to scandoubler to see if it shows something right?

Well, with the Arxon, given its usage of the Graphics slot, as long as the 4000 is powered, then its Always on, and yes that means you will get a scan doubled Kickstart screen (and boot menu if you use the mouse button trick to activate it).
