While the majority of laptops still use the 16:9 aspect ratio, we've seen many companies increasingly embrace taller aspect ratios over the last couple years. Lenovo, while also playing around with the likes of 16:10 laptop screens in other upcoming machines, is taking a wider approach. At CES this week, it announced a laptop with an ultrawide display. Oh, and it has a second screen next to the keyboard, too.

Lenovo says the ThinkBook Plus Gen 3 is the first machine to use a 17.3-inch 21:10 screen. We've seen ultrawide laptops before, but laptops with a screen that's wider than 16:9 are incredibly rare today.
