Display Output — CompTIA A+ Core 1 (220-1101) Practice Questions
Display output refers to the video interfaces and ports used to transmit image signals from a computer to a monitor or projector, including HDMI, DisplayPort, DVI, VGA, and USB-C with video capabilities. The 220-1101 exam covers maximum resolutions, refresh rates, and cable length limitations for each interface, as well as adapters needed to bridge incompatible connectors. Technicians must understand multi-monitor configurations and how graphics cards or integrated graphics handle multiple simultaneous display outputs. Troubleshooting display output issues, such as blank screens or resolution mismatches, is a practical skill tested on the exam.
