The LG B4 Oled TV series has four references, one more than in 2023, the LG OLED48B4 (48'', 122 cm), LG OLED55B4 (55'', 140 cm), LG OLED65B4 (65'' , 165 cm) and LG OLED77B4 (77'', 196 cm).
LG B4 Oled TV, light peak higher than that of LG C3 TVs
If LG C4 and LG G4 televisions benefit from the Evo label, this is not the case for the LG B4 models. The latter are therefore equipped with a so-called “classic†Oled panel offering a light peak approximately 30% lower than that of an LG C4 screen and 150% lower than that of an LG G4.
Oled TV LG B4, Alpha 8
We find on LG B4 televisions the chip of the LG QNED85T and LG QNED90T references already presented in our columns, i.e. the Alpha 8. Mix of the Alpha 7 Gen 4 of the 2023 vintage QNED TVs and the Alpha 9 Gen 7 present on the new LG QNED99T 2024 series in Ultra HD 8K, it has many new AI Picture Pro and AI Sound Pro features: Dynamic Tone Mapping process, AI Super Upscaling for the image, virtual surround 9.1.2 sound, AI Clear Sound or Dynamic Sound Booster. Without forgetting of course AI ThinQ and the webOS interface which we will come back to in more detail in a future news.
LG B4 Oled TV, main specifications
For the rest of the specifications, Oled LG B4 televisions integrate the new WebOS interface, which is updated for the next four years (see our CES 24 news > LG WebOS Re:New function, 4 years of updates up-to-date guarantees), HDR Dolby Vision (now active with Filmmaker mode), HDR Dolby Vision Gaming (120 Hz), HDR Dolby Vision IQ, HDR HLG, Dolby Atmos compatibility. All implemented through a native 10-bit Ultra HD 4K flat 120 Hz Oled panel, almost complete coverage of the DCI-P3 color space (99%). We also note the certification with the recent Matter home automation standard.
As for flagship services, GeForce Now, Shadow, Blacknut and Utomik Cloud are still present. Ditto for the 2024 vintage Game Optimizer mode which brings together all the TV settings involved with a video game signal and allows the user to configure them individually as they wish. In 2024, LG B4 TVs will benefit from a preview of VRR G-Sync 120 Hz certification in addition to AMD FreeSync Premium. Namely, LG CB TVs are Intertek certified, a label which guarantees a response time of less than 0.1 ms, coverage of the Adobe RGB gamut greater than 90% and accuracy of the EOTF curve above 90%.
TV Oled B4, Smart TV ThinQ AI
The LG OLED B4 screens of course offer the LG ThinQ AI 2024 function with integrated Amazon Alexa and Google Assistant. These voice assistants are both accessible directly on the remote control via a dedicated button but also through the TV, without the need for the zappette). In addition to communicating by voice directly with its screen, such as with a Google Home or Amazon Echo speaker, it is possible to control other Google Assistant and Alexa certified devices shared on the local network by voice through the television. Everything allows access to the internet and specific services (LG App Store online store, chat on social networks, etc.), or even directly to the web as on a computer. Of course, Miracast, Bluetooth, Wi-Fi 6e, Chromecast (built-in), AirPlay 2 and HomeKit are back on the menu.
Otherwise, ThinQ AI has its own artificial intelligence module to easily and quickly control the TV. But the Conversational mode available on Alexa and even more so on Google Assistant is not appropriate here. ThinQ AI is perfect for giving an order to the TV, for example "Turn up the volume" or "Activate Cinema mode", but it is Google Assistant who takes control during a more in-depth question, on an actor displayed on the screen. screen or more generally to search for information related or not to the content broadcast. We must also not forget that the Magic Remote incorporates a microphone for ergonomics, via voice control, which is always excellent.
Oled TV LG B4, and the rest?
For the rest, we find on LG B4 TVs a simple DVB-T2, DVB-S2 and DVB-C tuner, an Auto Level function (to avoid sudden changes in sound volume when changing sources), Fransat and Canal Ready certifications, HBBTV compatibility, the DVR function to record your favorite programs via one of the three USB Host 2.0 ports on a suitable key or an external HDD, all associated with the Time Shifting function. Of course, a virtual keyboard is available via the LG Remote iOS/Android/Windows Phone application to use suitable smartphones/tablets as remote controls.
Finally, if LG does not give details on the Input Lag of 2024 Oled TVs, it should at least be at the level of that of 2022 TVs, i.e. around 10 ms (6 ms in 4K/120 ) with HDR Game mode.
LG B4 Oled TV, HDMI 2.1/HDCP 2.3
The connectivity of the LG B4 screens brings together two HDCP 2.3 certified HDMI CEC 2.1 inputs, one of which has the eARC function, plus two HDMI CEC 2.0 inputs. There is also an optical output, plus three USB Host ports (including one 3.0) compatible with Fat32 and NTFS, a CI+ port and an Ethernet port. In addition to VP9 and AV1, MP3, AAC, PCM, WMA, VC-1 and Jpeg compatibility are ensured, with the MKV container.
