Being a CRT television, the KV-20VS40 is bulky and relatively heavy compared to modern flat-panel displays. It supports only standard definition resolutions, lacking HD or digital input support. The 4:3 aspect ratio limits widescreen content display without letterboxing. Analog connection options like composite and S-Video are now largely obsolete. It lacks modern smart features such as internet connectivity or built-in streaming apps. Over time, CRT phosphor degradation and component aging may affect picture quality and serviceability.
