Abstract
A computer monitor includes a plurality of screen-control switches, an input/output circuit adapted to be connected to a computer, and a processor connected to the screen-control switches and the input/output circuit, and adapted to detect if a universal serial bus (USB) standard compliant-interface was established between the input/output circuit and the computer. The processor performs a hardware-based on-screen display routine to adjust screen characteristics of the computer monitor when the screen-control switches are operated and the USB standard compliant-interface is not detected. The processor generates a command that is assigned to an operated one of the screen-control switches and that is to be received by the computer via the USB standard compliant-interface when the USB standard compliant-interface is detected.
