The exact origin of this clip is not documented, so it circulates mainly as a standalone reaction sound shared between meme pages and short video edits. Its appeal comes from how specific the phrase is: HD is a term almost everyone has heard, which makes admitting confusion instantly funny and easy to reuse. Creators pair it with pixelated footage, old monitors and pretend tech support scenes, and it has stayed useful because the joke does not rely on a dated reference or a recognisable character voice.
