Again, given the fact that your display geometry is likely less than 1280 wide, you'll simply lose information for FFTs larger than that.
I one is looking for weak CW signals, in a waterfall, wouldn't a wide bin, make this signal invisible in among the noise? If more bins fit in one pixel, there could be a mode where the bin with the most power is displayed. If this is complete non-sense, how would you implement looking for faint cw carriers, in like EME applications?
