it has a passthrough port. when/if you get a scandoubler for your A2000, you can route the native graphics from there to have a single monitor solution. The CV3d lacks this.
But please avoid Picasso IVs. They are expensive and breaking that scandoubler from the board for a measly A2000 is sacrilege. Believe me you will get fussed and bored with your A2000 soon, and go for a A4000 in the future, and you will regret breaking the scandoubler.
