I have a small card which fits over one of the chips of my A1200 and provides a VGA signal. Can't remember the name of the card offhand - haven't powered the A1200 up for about 3-4 years since the last time.

I think that if you use the RGB output, you can get 640x480 at 60 or 70Hz.

Probably an 'Indivison AGA' (Or 'OCS' if you have a 2000/500). Fits over the Lisa chip, and grabs the video output and scan doubles it to work with a standard VGA type monitor either via VGA or DVI. Can support resolutions up to 1280x1024.

  That rings a bell, indeed. Especially the phrase "scan doubler". Thanks! It's been so long since I really concentrated on the A1200/Amiga stuff in general, I've forgotten most of it :)

From the user manual (http://www.primrosebank.net/computers/amiga/documents/A1200%20(Commodore)%20-%20Manual-ENG.pdf http://www.primrosebank.net/computers/amiga/documents/A1200%...): An RGB monitor gives the highest quality picture, and allows you the widest selection of the Amiga's many display modes. Several types of analog RGB monitors can be used with the A1200, including multiscan, 15 KHz, and VGAlSVGA monitors. A multiscan (multiple horizontal scan rate or "multisync") RGB monitor provides the greatest flexibility. A multiscan monitor is required if you wish to use display modes that have different horizontal scan rates. A 15 KHz analog RGB monitor can display only the Amiga's default display mode and other 15 KHz scan rate modes. A VGA or SVGA type monitor can display the Amiga's de-interlaced and higher resolution modes, but not the standard 15 KHz video modes. Connect a 15 KHz monitor with a 23-pin female connector, such as the Commodore 1084 or 10848, directly to the A1200 VIDEO port. For a monitor such as a multiscan, VGA, or 8VGA model that has a small 15-pin VGA-style connector, connect the 23-pin to 15-pin adapter included with the A1200 to the VIDEO port, then connect the monitor cable to the adapter. With the proper adapter cable, a television with a SCART input can be used as a 15 KHz RGB monitor. See the "SCART Televisions" section below for more information.
