I have two computers connected to the same monitor: - MacBook Pro 15 inch 2018 via USB-C to DisplayPort cable - Windows desktop with GeForce GTX 1060 – LG 27GN950 (3840 x 2160, 144 Hz) Both computers use 3840 x 2160 (2160p/4K UHD 1 – Ultra High Definition) at 120 Hz. The MacBook is used for programming and has no stability issues. Windows computer is used for gaming and sometimes shows some static lines or shuts down completely for a second. With a direct connection using a high-quality DisplayPort cable, these problems do not arise. The device is well made. I like the heaviness of the metal body and the LEDs are visible but not obnoxiously bright. I wish the cable routing was simpler so the wires don't stick out on either side. it would be great.
