Although there is a large variety of peripherals you can use with your system, you only need a few to get started: Plug in your mouse and keyboard. This is what you will use to navigate your PC. Plug in your display cable. This is typically an HDMI, DisplayPort, or in some cases, a DVI cable. If your system has a graphics card, ensure your display cable is plugged into the graphics card for best performance. Plug in your network cable. If wired internet (ethernet) is available, plug in your ethernet cable. If you do not have an ethernet connection available, connect to your Wi-Fi network once the PC is on. Optional: Miscellaneous devices such as printers, scanners, webcams, game controllers, audio hardware, external drives, etc.
