Product details:

Designed to provide programmers content creators designers and office workers a large and highly flexible viewing space the DualUp stacks two QHD screens atop each other to create a single 2560 x 2880 resolution display with a 16:18 aspect ratio. This vertical design helps to save desk space while offering all the benefits of a dual-monitor setup such as viewing multiple applications and windows at the same time. A built-in ambient light sensor provides extended viewing comfort by automatically optimizing the screen's brightness according to your environment's changing conditions. The screen itself is designed to deliver clear color-accurate images with support for high-dynamic range. Connect the LG DualUp to your system through the two HDMI ports or the DisplayPort input. Alternatively you can reduce desktop clutter by using the USB-C port to transfer video data and up to 90W of power over a single cable with compatible laptops. You can place video feeds from multiple inputs next to each other in Picture-by-Picture mode. Additionally the USB-C connection allows you to take advantage of the monitor's built-in KVM switch to control multiple computers with one mouse and keyboard set. Other features include integrated stereo speakers and a dual-port USB hub.Stack it up
