As 2-in-1 convertibles, both of the laptops in our comparison come with touch screen displays that fold part or all of the way back for major flexibility around usage. The ThinkPad X1 Yoga features a larger display at 14 inches, compared to the 13.3-inch display on the Latitude 7390 2-in-1.
The Latitude comes with FHD (1,920 x 1,080) resolution and 255 nits of brightness, along with Corning Gorilla Glass 4 for durability. The X1 Yoga doesn't have Gorilla Glass, but it has three configuration options with some resolution and brightness advantages.
The base model of the X1 Yoga features the same FHD resolution as the Latitude 2-in-1, but is a tad brighter at 270 nits. The two other X1 Yoga configurations add more pixels and some other flourishes: WQHD (2,560 x 1,440) resolution with 270 nits of brightness, and at the highest end, WQHD resolution with 500 nits of brightness and support for Dolby Vision HDR (for enhanced image quality). Thus, for users that favor the best display quality possible, the top-end configuration of the 3rd gen ThinkPad X1 Yoga may be the better choice.
