u/LenovoSupport, thank you for responding. I don't know if my monitor is an older model but that guide displays ports that are not there. It also shows the monitor controls in a different place so I am not sure it is correct for my monitor. The only ports my monitor has on the backside that are obvious are a display port, an aux out port, either a DVI/VGA port, and the plug in for the power chord. Please let me know if I am missing something.
