HDMI connections can enhance video quality, but the actual resolution remains the same as component-video connections. Differences in brightness, color, and crispness may occur, and results can vary based on the specific player and TV. HDMI is often necessary for high-definition output, as many players do not allow HD output through component cables due to copyright protection measures. DVD players do not typically degrade in HD capabilities as they age, although general wear and tear can affect performance. To optimize HD viewing, it's essential to adjust TV picture settings and ensure the player is set to the correct resolution. High-bandwidth Digital Content Protection (HDCP) is crucial for maintaining digital signal integrity between devices. Standard DVD players usually do not upconvert via component-video outputs, while HD DVD players can deliver HD output through both HDMI and component connections, but may restrict upconversion of standard DVDs through component. Quality differences in HDMI cables are minimal unless longer lengths are required, and affordable options are available online.
