You probably won't be able to go any higher than a width of 720. That said, it looks like either the driver is not responding properly or the application doesn't realize that the driver returned it's maximum field width (the V4L2 API specifies that in the S_FMT call that if the calling application specifies an invalid width, the driver can return a valid width and the application should recognize and use that value).
