Assumptions:
horizontal: back porch = sync pulse = 25% of blanking time

Hi Bernhard

Let me k'now, how to hell you have calculate this Modeline "2048x2048" 257.00 2048 2080 2112 2174 2048 2051 2055 2080 ???
Whats are the correct syntax for Modeline?
i'm not stupid, but anything are wrong!!!!
The corrects value are:

Hper
2816 pixel
Hres
2048 pixel
Hpb
727 pixel
Hfp
11 pixel
Hsync width
30 pixel
Vper
2114 lines
Vres
2048 lines
Vbp
60 lines
Vfp
3 lines
Vsync width
3 lines
Pixel clock
357,181MHz

unfortunately with this Modeline “2048x2048“ 357.18 2048 2059 2089 2816 2048 2051 2054 2114 –Hsync -Vsync my ISIS 471 will not work.
strangely with this Modeline "2048x2048" 257.00 2048 2080 2112 2174 2048 2051 2055 2080 i will get a Picture ---> see Post #25 can you explane me again Post #27 with the new values?
thx patrick
