LG B4 55" vs TCL Q7 55"
The Verdict
LG's B4 OLED delivers superior picture quality with perfect blacks, superior contrast, and exceptional brightness at 1100 nits thanks to its OLED panel technology and α8 Gen 7 processor. Gaming performance edges ahead with 1ms input lag versus TCL's 8ms, plus LG includes Dolby Vision IQ and Filmmaker Mode for content enthusiasts. TCL's Q7 offers compelling value at $499, featuring QLED brightness (1000 nits), Wi-Fi 6 connectivity, and respectable gaming features at a quarter of LG's price. Both support 120Hz refresh rates and VRR/ALLM. Audio is modest on both, though LG provides 40W versus TCL's 20W. For serious gamers and movie enthusiasts willing to invest, the B4's OLED superiority justifies the premium. Budget-conscious buyers should confidently choose the Q7, which delivers solid 4K gaming and streaming performance without breaking the bank.
