Yep. You do need at least a sound bar, or a stereo system with these. But most inbuilt TV audio is pretty terrible to begin with, at least on low to mid end tvs.

Actually he got a good deal. Those screens are more expensive because they don’t come bundled with ad riddled toiletware, and they often have a longer lifespan to accomodate being on for so long every day. Depends on how much it got used already though.
