Overview

The LG UBK90 is a dedicated 4K Ultra HD Blu-ray player that handles the full spectrum of physical disc formats — 4K UHD Blu-ray, standard Blu-ray, and DVD. Its headline feature for movie enthusiasts is dual HDR support: both Dolby Vision and HDR10, which means it can deliver the best possible picture regardless of which HDR format a particular disc uses. It also supports high-resolution audio passthrough over HDMI, making it a solid anchor for a home theater system with a capable receiver. Built-in Wi-Fi and Ethernet add 4K streaming capability, turning it into a single-box solution for both disc and digital content.

This renewed unit makes the most sense for someone who values disc-based 4K quality — which still exceeds streaming in bitrate and audio fidelity — but does not want to pay full retail. The UBK90 sits in LG's upper tier of players, originally positioned as a premium model. Setup is straightforward: connect HDMI to your TV or receiver, join your network, and you are ready for both discs and streaming. The player is not going to replace a dedicated Apple TV or Fire Stick for app variety, but if your primary goal is the best possible playback from your 4K Blu-ray collection with streaming as a bonus, the UBK90 delivers that at a compelling renewed price point.

👎 Cons

  • The built-in smart platform has a limited app library compared to dedicated streaming devices like Roku or Apple TV
  • Loading times for 4K Blu-ray discs can be noticeably slow, sometimes taking 30 seconds or more to start playback
  • No analog audio outputs — if your setup relies on older RCA connections, you will need an HDMI audio extractor
