BVision display of 15KHz screens
« on: October 31, 2008, 11:48:33 AM »
The BVision in the A1200 I'm using seems to display native 15KHz screenmodes. For example, when I'm on the Kickstart screen or the early startup screen, I can see this both on the TV connected to the composite output, and also on the VGA monitor connected to the BVision. How does it do this? Nothing is connected to the custom chips, so where is it getting the 15KHz signal from?
