QN90A 75 Neo QLED 4K Smart TV
The LG OLED77B5PUA 77" Class B5 Series OLED AI 4K UHD Smart webOS TV. And the Samsung QN90A 75" Neo QLED 4K Smart TV represent two distinct approaches to large-screen 4K performance. Public specifications and retailer listings show the LG model uses a 77-inch OLED panel with a 120 Hz refresh rate, integrated AI processing. And the webOS platform, currently priced at $2,999.99. In contrast, the Samsung QN90A relies on Neo QLED backlighting technology in a 75-inch size, with details on its exact refresh rate. And peak brightness still pending official confirmation from the manufacturer. Review aggregation sites note the LG’s self-emissive pixels deliver consistent black levels. And wide viewing angles, while early coverage of the Samsung highlights its brightness potential and Mini-LED architecture suited for brighter rooms. Synthesis of available data indicates clear trade-offs in panel type, screen size, and specification maturity between the two sets. Bottom line: choose the LG OLED77B5PUA for its confirmed 77-inch OLED panel, 120 Hz refresh rate. And known pricing, or select the Samsung QN90A if a Neo QLED design is preferred while awaiting fuller specifications.
