LG UBK90 4K Ultra-HD Blu-ray Player Dolby Vision

The LG UBK90 is a dedicated 4K Ultra HD Blu-ray player designed for home theater setups where picture and sound quality are the top priority. At its core is LG's a7 Gen 2 intelligent processor, which applies real-time optimization to both video and audio signals — reducing noise, enhancing detail, and adjusting output to match the content being played. Dolby Vision HDR support means compatible discs and streaming content benefit from dynamic metadata that adjusts brightness, contrast, and color on a scene-by-scene or even frame-by-frame basis, producing a noticeably more lifelike image than static HDR formats alone.

On the audio side, the UBK90 supports Dolby Atmos pass-through, enabling object-based surround sound that places audio elements in three-dimensional space when connected to a compatible receiver or soundbar. It also handles high-resolution audio formats, making it a capable player for music enthusiasts as well as film viewers. LG ThinQ AI integration adds voice control capabilities and smart home connectivity for hands-free operation. Whether spinning a 4K disc from your collection or streaming content from supported services, the UBK90 aims to be the centerpiece of a premium home entertainment system that delivers reference-quality playback across formats.
