LG QNED80 55" vs Samsung QN90D 65"
The Verdict
LG's QNED80 55-inch offers exceptional value at $699, delivering solid picture quality with quantum dot technology, 700 nits brightness, and native 120Hz gaming performance. Its α8 AI Processor handles 4K upscaling competently, while 20W speakers provide adequate audio for casual viewing. The 10ms input lag serves gamers reasonably well, and webOS 24 with multi-assistant support covers most streaming needs. However, Samsung's QN90D 65-inch represents a different tier entirely. At $1799, it commands premium pricing but justifies it through Neo QLED mini-LED technology delivering an extraordinary 4000 nits peak brightness, drastically superior contrast ratios, and exceptional color accuracy. The 65-inch screen provides 57% more viewing area than LG's 55-inch model. Samsung's 4.2.2 object tracking speaker system with 60W output crushes LG's basic 2.0ch configuration. Gaming enthusiasts will appreciate the QN90D's 5ms input lag versus LG's 10ms, alongside more advanced processing via the Neural Quantum Processor. Budget-conscious buyers seeking 4K HDR gaming on a reasonable screen should choose the LG QNED80. Those wanting premium picture quality, significantly larger screen real estate, superior audio, and cutting-edge mini-LED technology justifying the investment should invest in Samsung's QN90D.
