Sorry , it took a while, start here for 1360x768 (you won't get 1366 out 
of a PC, something to do with the width being divisible by 8 I think) 
this works perfectly on my Sharp Aquos LC-32G2M
        Modeline "1360x768"   85.974   1360 1370 1402 1780   768 778 783 
805  -hsync -vsync
you may also gt 1368x768 working with something like,
    Modeline "1368x768"   86.3605   1368 1378 1410 1788   768 778 783 
805  -hsync -vsync
I haven't yet but I haven't tried very hard

The best modeline calculator on the net (that I've found) is

Good luck.
