The LG OLED55B4PUA 55-Inch 4K Smart OLED TV and the LG OLED B4 55" TV share identical panel technology, 4K resolution, brightness characteristics. And overall picture processing according to public specifications and aggregated user reports. Both models deliver the deep blacks, wide viewing angles, and accurate color reproduction typical of LG’s entry-level OLED lineup at the $1,099.99 price point, with the same smart platform and connectivity options. Differences surface mainly in variable refresh rate support: the OLED55B4PUA includes VRR and G-Sync compatibility for smoother gameplay on compatible consoles. And PCs, while the standard OLED B4 omits these features yet retains the same core visual performance. The short version: choose the LG OLED55B4PUA if VRR. And G-Sync gaming matter to you; otherwise the LG OLED B4 provides equivalent everyday picture quality for the same cost.

Verdict: Pick LG OLED55B4PUA if you need VRR/G‑Sync gaming performance; pick LG OLED B4 if you are fine without VRR and want the same picture quality at the same price. Both cost $1,099.99 and share core OLED specs, so the decision hinges on the presence of VRR and HDMI 2.1 on all ports.
