This 2021 LG Mini-LED flagship splits the difference between LED and OLED, with strong dimming and saturation. All four HDMI ports are HDMI 2.1 with VRR and ALLM, but LG rates them at up to 40Gbps, and 4K@120Hz runs on HDMI 3 and 4 only. eARC runs on HDMI 3 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.
2021 LG QNED91 Mini LED with α7 AI Processor Gen4, 120Hz native, first QNED Mini LED generation.

Notes & Compatibility
HDMI: 4x HDMI 2.1 (40Gbps, VRR, ALLM; 4K@120Hz on HDMI 3 and 4 only). eARC: HDMI 3. USB: 3x USB 2.0 Type-A. LG’s own specification sheet for this model rates the HDMI inputs at “up to 40Gbps bandwidth, allowing up to 4K 120Hz 4:4:4 @ 10-bit” — not the 48Gbps the HDMI 2.1 badge permits. An Ultra High Speed (48Gbps) cable clears that comfortably and is still the right cable to buy, but the ceiling here belongs to the TV, not to the lead.
