- I use an 14" VGA Monitor with my A1200. In 1084/TV mode I set the screen
- preferences to some Multiscan Productivity (640*480, it might also to be
- necessary to copy VGAonly monitor drivers if memory serves me correctly)
- and saved it for the next
- reboot. Then I connected it to the VGA monitor and rebooted. That's it.
- Of course you can't run games that take over the machine and force 15kHz.
- And: keep your old 1084/TV and a copy of the workbench with 15kHz startup
- to be on the safe side.
