You should have said that before. With that information you can calculate the correct modeline immediately.

clock=85.800
hres=1360
vres=768
so:
Modeline "1360x768" 85.800 1360 aaaa bbbb cccc 768 ddd eee fff +HSync +Vsync

cccc=clock/hfreq = 85800/47.712 = 1800 (rounded to 8-multiple)
eee = hfreq/vfreq = (85800/1800)/60.0015 = 794

aaaa and bbbb are between 1360 and cccc (determining horizontal position)
same for ddd and eee.

Maybe if you refine your modeline you get sharper results.
