I... doubt it?  Standard timing descriptors are a tuple of

* width in character cells (ie, 8 pixels)
* one of four aspect ratios
* refresh rate

So you're only ever going to have 1360 or 1368, and then in integer math
I think you could only possibly ever get:

a) 1360 * 9 / 16 = 765
b) 1368 * 9 / 16 = 769

If you're managing to get something else I'm a little concerned, and
would really be delighted to see the EDID block for it.
