ECS and AGA could do non-interlaced 400 line scanning. ECS could do non-interlaced 640x480 (+overscan) with 4 colors. In the documentation, 35 nanosecond pixel

AGA same, but with 256 (or 262144 HAM) colors.
- icedchai 2y agoAlmost nobody had a monitor that supported those modes.
- ChainOfFools 2y agoExactly what I was thinking of with respect to kludges necessary for backwards compatibility. I think Commodore made one monitor that supported a bi-modal scan rate, and it was something like twice as expensive as the the regular Amiga monitor range. I also recall a somewhat exotic NEC 17" flat-face CRT monitor that was completely out of the question pricewise for almost anybody except institutions, that also could do it by virtue of having a continuously variable sync clock from 15 khz up to 45 or so.
- vardump 2y agoPeople certainly had VGA monitors back then! The problem is not VGA 31 kHz modes, but old 15 kHz ones.
- icedchai 2y agoYes, I had one on my A3000 (which has a deinterlacer / scan doubler built in, so the old modes weren't a problem.) Most Amiga modes are 15 khz. The average person with an A500 or A1200 would have a 1084S and get zero value out of the new modes.
