LG OLED A2 55" vs TCL QM8 65"
The Verdict
LG's A2 OLED delivers exceptional contrast and perfect blacks at 55 inches, excelling in picture quality for cinema-focused viewing with true OLED technology and Dolby Vision support. TCL's QM8 jumps to 65 inches with Mini-LED backlighting, achieving dramatically higher brightness (5000 nits vs 500 nits), 120Hz refresh rate, VRR support, and superior gaming performance at 6ms input lag. Audio favors TCL with 50W 2.1ch speakers versus LG's modest 20W setup. Gaming-centric users benefit from TCL's low latency and variable refresh rate, while OLED purists prefer LG's superior contrast and thinner profile. TCL includes Wi-Fi 6 and an extra HDMI port. For $100 more, TCL offers significantly larger screen real estate, brighter HDR, gaming features, and stronger audio, making it better for sports, gaming, and bright rooms. LG suits dark-room film enthusiasts. TCL represents stronger overall value.
