LG G4 77" vs Samsung S90C 65" (4K OLED)
The Verdict
Both TVs deliver exceptional OLED picture quality with 4K resolution and 120Hz refresh rates, but they cater to different needs. The LG G4 77-inch commands attention with its massive screen size, superior peak brightness of 2,100 nits versus the Samsung's 1,500 nits, and advanced MLA technology that enhances contrast. Its 4.2-channel, 60-watt audio system significantly outperforms the S90C's 2.1-channel, 40-watt setup. Gaming performance slightly favors the LG with 1ms input lag compared to the S90C's 6ms, though both support VRR and ALLM. The Samsung S90C shines as a value proposition at $1,999, offering solid picture quality with QD-OLED technology and excellent brightness for its price point. Its 65-inch size suits smaller rooms better, and the ultra-thin 0.5-inch bezel design is sleeker. Wi-Fi 6 on the LG provides faster connectivity than the S90C's Wi-Fi 5. The $1,300 price difference is substantial. Choose the LG G4 if you prioritize maximum brightness, immersive sound, gaming performance, and have space for a 77-inch display. The Samsung S90C makes more sense for budget-conscious buyers seeking proven OLED quality in a more compact footprint.
