Display Cable — CompTIA A+ Core 1 (220-1101) Practice Questions
Display cables carry video signals between a computer's graphics output and its monitor or internal display, with common types including HDMI, DisplayPort, VGA, DVI, and the internal LVDS or eDP cables found in laptops. On the CompTIA A+ Core 1 exam, candidates must identify each connector type by appearance, understand the signal standards they support (analog versus digital, resolution and refresh rate limits), and know when a particular cable type is appropriate for a given setup. Damaged or incompatible display cables are a frequent cause of no-image, flickering, or color distortion symptoms, making cable identification a practical troubleshooting skill tested on the exam. The exam also distinguishes between video cable standards in terms of their support for audio-over-cable and maximum bandwidth.
