#ECS to 31Khz how?
If you have the super Denise, and WB 2.1, you have productivity mode. That will
give you 640×480, max 4 colors. You will still need a 15khz monitor for every
other mode. To be honest, get ICD's Flicker Free video 2. It installs under
your denise, leaving you video slot free. Not only will it deinterlace the
high res modes, but it gets rid of the annoying black lines in the lower res
mode. The effect is the same as Mode Promotion on the 4000.
