LG OLED B3

No, the LG OLED B3 maxes out at a 120Hz refresh rate at 4K resolution via its HDMI 2.1 ports. It is the step-down model from the LG C3 and lacks the 144Hz capability found on LG's premium G3 series. For most console gamers playing on a PS5 or Xbox Series X, 120Hz is the maximum supported frame rate anyway.

The LG OLED B3 features four HDMI ports, but only two of them (HDMI 3 and 4) are full-bandwidth HDMI 2.1 ports. This is a notable downgrade from the LG C-series, which typically features four full HDMI 2.1 ports. You will need to plug your next-gen gaming consoles and high-end PCs directly into ports 3 or 4 to utilize 4K at 120Hz and VRR.

The B3 is powered by the α7 (Alpha 7) Gen 6 4K AI Processor, whereas the more premium C3 uses the faster α9 Gen 6 processor. Because it uses the a7 chip and lacks the Brightness Booster technology of the higher-end models, the B3 has lower peak brightness. It performs well in moderate lighting but may struggle to counter heavy glare in a very sunny room.

Yes, the LG OLED B3 features an enhanced Audio Return Channel (eARC) port, typically located on HDMI 2, which supports uncompressed Dolby Atmos audio. You can connect a soundbar like the Sonos Arc or an AV receiver to this port to get immersive surround sound from internal apps like Netflix. It also supports DTS audio formats, which are often dropped by some other modern TV brands.
