The Samsung QN90C/QN90CD QLED is a high-end 4k TV released in 2023, sitting below the Samsung QN95C QLED. It replaces the Samsung QN90B QLED in Samsung's lineup, but it has more in common with the Samsung QN85B QLED. It's available in a wide range of sizes, from 43 to 85 inches, so there's something for everyone. It's powered by Samsung's Neural Quantum Processor 4k, which was first introduced in 2022 and is designed to deliver better upscaling, optimized on a scene-by-scene basis. Like other Samsung TVs, it uses Samsung's proprietary Tizen OS interface, which offers a large selection of apps and games. It's compatible with the Bixby and Alexa voice assistants, and it supports the Matter smart home standard, so you can control all of your Matter-compatible smart devices from your TV.
