Post-Purchase Truths

B4: 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.

G4: What to watch for

Hidden Cost
65" and larger models still omit tabletop stands in the US box.
Buyers planning to place the 65" or 77" on a media console must budget for a third-party or OEM VESA stand.
Software / Apps
webOS home screen features sponsored content & banner recommendations.
Navigating the smart interface prompts promotional banners unless manually restricted via deep privacy settings.
