Post-Purchase Truths

Samsung: What to watch for

Software / Apps
Smart TV interface runs sponsored ads and banner recommendations.
Like most modern smart TV platforms, the home menu highlights suggested streaming content and sponsored banner placement out of the box.
Ergonomics
Thin integrated TV speakers lack low-end bass punch.
Ultra-thin modern chassis leave minimal acoustic chamber depth, making a dedicated soundbar or audio system virtually mandatory for movie dialogues.
