LG QNED80 55" vs TCL QM8 65"
LG's QNED80 delivers solid mid-range performance with quantum dot technology and native 120Hz refresh rate at a competitive $699 price point. However, TCL's QM8 substantially outperforms it despite the higher $999 cost: its 65-inch mini-LED QLED panel achieves exceptional 5000-nit peak brightness versus LG's 700 nits, enabling superior contrast and HDR performance. Gaming advantages favor TCL with 6ms input lag compared to LG's 10ms, plus Wi-Fi 6 connectivity and Dolby Atmos audio (50W vs 20W). The QM8's larger screen and professional-grade picture processing make it the stronger choice for cinephiles and gamers willing to invest. LG remains excellent value for budget-conscious buyers seeking capable 4K gaming in a compact footprint, but TCL's superior brightness, contrast, and audio justify its premium for discerning viewers.
