I’ve always worked with an external monitor. After noticing eye strain with my previous low-resolution monitor, I decided to invest in a quality 4K monitor. Best decision ever. This monitor is also a hub with multiple USB C and USB 3.0 ports. I’m able to connect my webcam, keyboard, mouse, and music keyboard to it, and then run one USB C cable to my laptop. The USB C also sends power to my laptop, which eliminates the need for a laptop power brick!
