LG OLED BX 55-77″ OLED (2020)

This older OLED generation offers pixel-perfect contrast and black levels, but needs a modern receiver for gaming. Two HDMI 2.1 ports hit 4K@120Hz with VRR, but the other two cap out at 4K@60Hz — plan your source placement wisely. eARC runs on one input for lossless audio return to a soundbar. For the 2.1 ports, use Ultra High Speed HDMI cables — standard cables top out at 18Gbps. Here's every port and the cables you'll need.

2020 LG entry-level OLED BX with α7 AI Processor Gen3. Only 2 HDMI 2.1 ports.
