These days, if you're looking for a laptop with a 3:2 aspect ratio, you're largely limited to either a Surface or Huawei's MateBook line. But laptop makers are always considering new options, and it turns out Lenovo has at least experimented with a 3:2 aspect ratio for its business-focused ThinkPad X1 Carbon.

Lenovo recently showed off a prototype version of the ThinkPad X1 Carbon to Japanese publication PC Watch (via Notebook Check), and it varies quite a bit from what eventually hit the market. Namely, the "proof-of-concept" device included a 12-inch display instead of 14. Lenovo also experimented with a 3:2 aspect ratio for the screen.

Aside from the screen, Lenovo was also experimenting with some other interesting ideas. An expansion kit could be added to the bottom of the device to add more ports; an addition necessitated by the prototype's inclusion of only a single USB-C port. The company also toyed with the idea of adding a webcam into the bezel above the keyboard.
