LG OLED B3 65" vs TCL QM8 65"
The Verdict
LG's OLED B3 delivers superior picture quality with perfect blacks and exceptional contrast that OLED technology inherently provides, alongside a slimmer design and lower weight at 41.7 lbs versus TCL's 68.3 lbs. However, TCL's QM8 compensates with dramatically superior brightness (5000 nits vs 600 nits), making it significantly better for bright rooms and HDR content, plus its mini-LED backlight excels in gaming with a 6ms input lag compared to LG's 7ms. TCL also offers better audio (50W vs 20W), Wi-Fi 6 connectivity, and Dolby Vision IQ processing at $300 less. For dark room cinematic viewing and design elegance, the LG B3 reigns supreme; for bright environments, gaming performance, and budget consciousness, TCL's QM8 presents remarkable value and versatility. Choose based on room conditions: the LG for premium dark room performance, the TCL for overall capability and brightness.
