I have a satellite box which has a SCART for output and I want to connect it to an LG monitor which has a VGA connection and a DVI connection.

Is it possible with a cable or would I need some circuitry to convert the signals?

This isn't a duplicate of this as I want to the output to be SCART and the input VGA whereas that question is the opposite.

This is not possible without additional hardware.

While you may find some articles that have only passive components in schematics, like this one: http://www.idiots.org.uk/vga_rgb_scart/ (sites like this warn you that all you do - you do at your own risk).

The both cables have a separate lines for the Red, Green, and Blue signals. But the synchronization signal is transferred differently in these two standards. VGA uses separate H-Sync and V-Sync signals while Scart has only one composite synchronization signal. Here you may see the schematic of a simple converter that mixes up H-Sync and V-Sync of the VGA cable into the Video sync signal. However I would propose you to find a ready to use solution

Please expand on this answer. It is vague in its current form. –  user3463 Sep 30 '12 at 19:01
