LG G4 77" vs Roku Plus Series 55"
The Verdict
LG's G4 77" represents flagship OLED excellence with its MLA technology delivering 2100 nits peak brightness, 1ms input lag, and comprehensive gaming features including 120Hz VRR for next-gen consoles. Its α11 AI processor, 4.2ch 60W Dolby Atmos audio, and webOS 24 create an immersive premium experience justifying the $3299 investment.

Size and technology gap is substantial,LG excels for cinephiles and gamers demanding superior contrast, motion handling, and sound, while Roku suits budget-conscious viewers prioritizing streaming convenience. LG G4 77" is the clear winner for serious home theater; Roku Plus works as an affordable secondary set.
