Apparently, it may be possible to get the OS to output a higher resolution than the native one. It requires some config files [tweaking](https://www.reddit.com/r/apple/comments/2ia242/enabling_1920_x_1200_hidpi_resolution_on_the_13/). I can't vouch for this method.

If you just need to show, say, the middle third of the screen, then another possibility is to [zoom in](https://support.apple.com/kb/PH18385?locale=en_US) to provide a larger source for ffmpeg to upscale. Depending on the size of the area of interest, this might not make much difference.

Of course, I dare say, 1680 --> 1920 should be an easy upscale post-recording with hardly much difference in perceptual quality unless your items of interest are very small.
