LG B4 55" vs Samsung QN85C 65" (4K Neo QLED)
The Verdict
Both TVs deliver excellent 4K gaming performance at competitive price points, but they target different priorities. The LG B4 excels with OLED technology, delivering perfect blacks, infinite contrast, and superior picture quality in dark rooms thanks to its pixel-level light control. Its 1ms input lag makes it marginally better for competitive gaming, and the Dolby Vision IQ processing handles HDR exceptionally well. However, the Samsung QN85C counters with a larger 65-inch screen versus the LG's 55 inches, giving you 18 percent more display real estate for $200 more. Samsung's Neo QLED with mini-LED backlighting achieves slightly higher peak brightness at 1200 nits compared to LG's 1100 nits, performing better in bright rooms. The QN85C also offers superior audio with 60 watts and Object Tracking Sound versus LG's 40 watts and standard 2.0 channels. For gaming, both handle 120Hz and variable refresh rate, though the LG's 1ms response crushes Samsung's 9ms. If you prioritize picture quality and gaming response times in a smaller space, the LG B4 wins. If you want a larger screen with better brightness and audio for general viewing and bright environments, the Samsung QN85C justifies its premium.
