I didn’t expect to see an LG OLED drop under $500, but here we are. Best Buy has the LG 48-inch B4 OLED TV on sale for $499.99, slicing $200 off the usual price. That kind of discount on an OLED feels suspiciously generous, but I won’t ask questions.

OLED screens are famous for perfect blacks and vibrant colors, and this one delivers over 8.3 million self-lit pixels. The α8 AI Processor automatically sharpens the picture and fine-tunes the sound, so even old sitcom reruns will look and feel like a high-end experience.

Movie lovers will appreciate Dolby Vision, Dolby Atmos, and FILMMAKER MODE, which keep everything looking and sounding like the director intended. Gamers aren’t left out either. NVIDIA G-Sync, AMD FreeSync Premium, and VRR help prevent lag and screen tearing. The 120Hz refresh rate keeps fast-paced games running smoothly, and four HDMI 2.1 ports mean no one has to fight over connections.
