Today we put an unusual product to the test: a dual-screen accessory that attaches to a 16-inch laptop using a clamp rail, expanding your screen real estate by a total of two additional displays on the left and right. Both additional displays offer 2K resolution, 144 Hz, DCI-P3, all while being foldable and mobile. We test the folding displays in a triple-display setup.https://www.notebookcheck.net/Monduo-16-Pro-Duo-in-review-A-built-in-triple-monitor-setup-for-laptops.717489.0.html
The manufacturer not only needs to calibrate both displays similarly, they need a tool to calibrate the laptop monitor close to said displays or vice versa.
