What reviewers say
TechRadar and Tom's Guide praise rich colours, deep blacks, responsive gaming and the webOS interface. Both warn that limited brightness and reflections hinder bright-room viewing, with little picture improvement over the B4. Both recommend fuller external sound; TechRadar welcomes the AI tools more readily than Tom's Guide.
