LG G4 77" vs Samsung QN90C 65" (4K Neo QLED)
The Verdict
LG's G4 77" OLED delivers superior picture quality with its advanced MLA technology, achieving deeper blacks and superior contrast than Samsung's Neo QLED approach, plus brighter peak brightness at 2100 nits versus 2000 nits. Gaming performance slightly favors LG with 1ms input lag compared to Samsung's 6ms, though both support 120Hz refresh rates. Samsung's 65" provides excellent value at $1799, using efficient mini-LED backlighting with 32 zones of dimming for strong HDR performance. Audio systems are comparably matched at 60 watts with Dolby Atmos support. However, the 12-inch diagonal difference fundamentally changes the viewing experience,LG's 77" commands a premium that matches its larger screen and superior OLED technology. For cinephiles and gamers with sufficient space and budget, LG G4 77" justifies its $3299 price tag. Budget-conscious buyers seeking excellent performance in a mid-size package should consider Samsung QN90C 65". LG edges ahead due to display supremacy and immersive scale.
