Component video uses three analog signals (Y, Pb, Pr) over 75-ohm RCA leads to preserve color detail. It still serves legacy gear, but HDMI now handles higher bandwidth, audio, and copy protection for modern 4K/HDR content.
An updated explanation of what "HDTV Ready" meant, why the label was useful in the 2000s, and what buyers should check today - native resolution, inputs (HDMI/HDCP), and modern standards like 4K/UHD.
DVI-D is the digital-only DVI connector that brought cleaner, higher-resolution video to older flat panels and PCs. Today it still works well for legacy monitors and basic desktop setups, but HDMI and DisplayPort are better choices for audio, higher resolutions, and modern features.
"HD Ready" originally meant a TV could accept HD signals (720p/1080i) but didn't guarantee a native 1080p panel or built-in tuner. Today, look for native resolution, HDMI version, HDR, and HDCP support rather than legacy badges.
DVI and HDMI use compatible digital video signaling, so passive DVI↔HDMI cables pass video reliably. HDMI adds audio and modern AV features (ARC/eARC, CEC, higher bandwidths) that DVI lacks. Use passive adapters for video-only needs; use active converters or HDMI gear when you need audio or advanced HDMI features.
