Yes, AGA and all Amigas can disply 31khz with software and Workbench......just simply Drag the Multiscan Monitor and DblPAL and DblNTSC monitor icons from your Workbench:Storage drawer............and drop it into the Workbench:Devs/DosDRIVERS drawer, reboot.....and select Multiscan Productivity mode (31khz VGA0 or DblNTSV/PAL (27 - 29khz? but still VGA)
its that easy.
The best solution?

? get the 1942 Commodore monitor.it display VGA and regular RGB...basically all AGA screen modes.
