Review on BenQ Proprietary Ultra Slim AmazonBasics DisplayPort 24", 1920X1080, Frameless, IPS by Joe Burke

This is a very good monitor. However, I needed a monitor with line-in and built-in speakers. An advertisement for the product featured a wire connector. I assumed speakers because why would a monitor have a line in without speakers? However, when I set up the monitor, I didn't find the line-in port where it should be. Even the accompanying documentation in the package lists the line-in port for this monitor model. (GL2580) But he's gone. This is a showstopper for me. I don't understand why the declaration and documentation show a function that doesn't exist.
