Re: LCD TV, SuSE 10.1 No valid modes for "1366x768";
Decrease the numbers 1416 and 1448 each by the same amount to shift the picture to the right. E.g. subtract 16 or 32 from both.
You can also experiment with the + and - on hsync and vsync.
When it is not possible to get it OK this way (e.g. because the picture really is too wide) you could try increasing the flyback delay, like this:
Modeline "1368x768" 85.25 1368 1440 1576 1784 768 771 781 798
But that looks more like what you already had.
