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.

Pros & Cons

LG G4 77"

Pros

  • MLA panel pushes OLED brightness to 2,100+ nits — closes the gap with Mini-LED
  • α11 AI processor is LG's most powerful, with superior upscaling and AI enhancements
  • Gallery design meant to hang flush to the wall with no gap

Cons

  • 77 inches is too large for many rooms and viewing distances under 10 feet

Samsung S90C 65" (4K OLED)

  • Wider color gamut and higher brightness than traditional WOLED panels
  • Infinite contrast with no light bleed or blooming
  • Excellent for gaming with 4K@144Hz, VRR, and low input lag

Cons
