LG G4 77" vs Samsung QN900D 65" (8K)
The Verdict
LG's 77-inch G4 OLED delivers exceptional picture quality with perfect blacks and outstanding contrast through its Micro Lens Array technology, achieving 2100 nits peak brightness with Dolby Vision IQ support. Samsung's 65-inch QN900D counters with cutting-edge 8K resolution and Mini-LED backlighting that reaches an impressive 4000 nits, plus superior audio with 6.2.4ch Object Tracking Sound Pro (90W vs LG's 60W). Gaming performance slightly favors LG with 1ms input lag versus Samsung's 5ms. However, Samsung's 8K capabilities feel premature given minimal content availability, while LG's larger 77-inch size, proven OLED reliability, and superior contrast make it more practical for most viewers. Pricing heavily influences the decision: LG costs $1,700 less. For mainstream viewing and gaming, LG G4 77" provides better value and more immediately noticeable improvements. Samsung suits those specifically investing in future-proof 8K capability.
