  • The Best “Entry Level” OLED The Best “Entry Level” OLED
This TV is so good it feels wrong to call it “entry level”. Beautiful colors, inky blacks, infinite contrast, and great viewing angles. The bonus over Samsung is DolbyVision. The B5 is a perfect bedroom TV, and it will great anywhere you can control lighting. I have paired mine with an LG S60T soundbar. Connecting it eARC was effortless, and has enabled WOW! orchestra. Just buy it already. ... show more

  • LG’s new TV remote is awful
This is the eighth day since the TV was delivered. The TV seems to be beautiful and works fine. But the remote that comes with it is nothing short of awful. The problem was I could not turn the TV on or off using the remote. As you can imagine this is a true bummer. There are no manuals regarding the remote. I’m instructed to turn on the television and use the guide provided on the TV. What an absolutely time waste!! If I had known this before, I would not have bought an LG TV. I’ve had over three hours of chats with LG support. I shouldn’t have to pay almost $1000 for a television and then invest over three hours of my time trying to make it work. It should work right out of the box. Perhaps we have finally gotten the problem figured out. I’ll find out tonight. ... show more

  • LG OLED B5 Review: Excellent Picture Quality, But Serious Smart Home and Power Management Issues
I purchased an LG OLED B5 and have been very impressed with the picture quality, brightness, and overall viewing experience. Unfortunately, I have encountered a serious issue involving the television’s advertised smart home functionality that significantly impacts daily use. My television is connected via Ethernet and integrated with Apple HomeKit, Apple TV, and the LG ThinQ app. One of the advertised features of the television is remote power control through these platforms. The problem is that the television frequently powers itself back on approximately 30 to 60 seconds after being turned off. This occurs when the TV is turned off using: * Apple HomeKit scenes * The LG ThinQ app * Smart home routines The television typically returns to the previous Apple TV input, usually displaying the Apple TV screensaver. I have spent considerable time troubleshooting this issue. The following settings have been disabled: * SIMPLINK (HDMI-CEC) * Quick Start+ * Always Ready * Bluetooth wake * Network IP Control The television is connected via Ethernet, and “TV On With Mobile” and Wake on LAN must remain enabled because disabling these settings prevents both LG ThinQ and Apple HomeKit from turning the television on remotely. The result is that owners must choose between: 1. Allowing the TV to randomly turn itself back on. 2. Disabling the very smart home features that are advertised as part of the product. What makes this especially frustrating is that I also own an older LG C2 television on the same network, using the same Apple TV, HomeKit, and Apple Home environment. The C2 does not exhibit any of these behaviors. This strongly suggests that the issue is specific to the B5 or its software implementation. I contacted LG support through the ThinQ support system. After basic troubleshooting, support advised disabling the settings required for remote operation. When I explained that this also disables HomeKit and ThinQ power-on functionality, I was referred to another department without receiving a solution. The picture quality of the B5 is excellent. However, prospective buyers who intend to use: * Apple HomeKit * LG ThinQ * Apple TV integration * remote power control * smart home scenes * Ethernet-based control should be aware that the television may repeatedly power itself back on after shutdown unless these features are disabled. If you plan to use the B5 as a traditional television with the remote, you may never encounter this issue. If you are purchasing the television specifically for its modern smart home capabilities, you should carefully evaluate whether these features currently function reliably in your environment. ... show more
