A SCART to HDMI adapter converts the SCART analog signal to a digital HDMI format, allowing you to connect older SCART output devices to modern HDMI-equipped displays. While the adapter facilitates the connection between different technology generations, it does not inherently improve the original SCART signal quality. The resulting video quality will largely depend on the source signal and the adapter's conversion capabilities, with the primary benefit being compatibility with newer display technology rather than enhanced resolution.
