The Verge posted a review of one of the world's first 2019 OLED laptops, the HP 2019 Spectre x360 15. The reviewer loves the OLED display: "The Spectre x360 15’s display is tremendous, and I see no reason why someone would pick an LCD over this OLED, given the option. It’s absolutely worth the higher cost (Ed: around $400)."
HP's Spectre x360 15 features an Intel Core i7 CPU, 16 GB of RAM and 512 GB of SSD storage. The OLED display is a 15.6" 3840x2160 panel produced by SDC. HP's Spectre x360 15 laptops are now shipping, the OLED models start at $2,299.
