LG B4 55" vs TCL Q7 55" (QLED)
The Verdict
LG's B4 OLED delivers superior picture quality with perfect blacks, exceptional contrast, and 1100 nits peak brightness ideal for bright rooms, plus Dolby Vision IQ and filmmaker-grade processing. Its 1ms input lag crushes TCL's 7ms for competitive gaming. WebOS 24 with ThinQ AI offers more customization than Google TV. However, TCL's Q7 QLED remains impressive for the price,full array local dimming and 1000 nits brightness handle most content admirably, with snappier Wi-Fi 6 connectivity and lighter 31.3-pound design. Both feature 120Hz refresh rates and ALLM support. Budget-conscious buyers accepting slightly higher input lag and less dramatic contrast will appreciate Q7's $650 savings. Serious cinephiles and competitive gamers should invest in the B4's OLED superiority, though premium positioning demands careful consideration of viewing habits.
