What Buyers Say
LG PK640S Series PK640S 86"
The LG 50UM340E commercial TV has received very poor reviews, with users citing extremely limited capabilities such as no scheduling for power on/off and poor third-party app compatibility. One verified buyer had to connect a Raspberry Pi just to get content displayed, and LG's management software was inaccessible. Additionally, one review mentions the TV never arrived, and another is a non-review. The Q&A confirms it cannot be mounted vertically, but does support USB playback.
Pros
- USB playback support
- Built-in digital signage features
Cons
- No power on/off scheduling
- Poor third-party app compatibility
- Inaccessible management software
- Cannot be mounted vertically
- Useless manual
