To make a long story short, the LG C4 Oled TV series offers more or less the specifications of the 2023 vintage LG C3 televisions, with some differences. But the developments of the LG C4 series, compared to those of the LG M4 Evo and LG G4 Evo series, are incremental.
LG C4 Oled TV, light peak higher than that of LG C3 TVs££££
Apart from offering a light peak higher than that of LG C3 screens, it is difficult to know more about the performance of the LG C4 diffusers in the area. We remember that LG representatives, during their presentation of the 2023 range a few hours before the opening of the CES show in Las Vegas last January, had put forward a value for the peak light of LG C3 TVs approximately 20% higher than that LG C2s. To see if it is the same in 2024 with LG C4 TVs Vs LG C3 models. We will also see if LG will provide the information in a few days, as a preamble to CES in Las Vegas 2024, which will be held from January 9 to January 12, 2025.
LG C4 TV, Brightness Booster technology ££££
Of course, as the name of this TV series indicates, we find the Oled Evo panel of the LG C3 televisions, therefore an Oled EX panel from LG Display . Like the LG C2/C3 series 2022/2023, the 42'' and 48'' specimens do not have it. LG Electronics indicates that the reduced pitch size of the 42'' and 48'' Oled panels does not allow you to benefit from the increased brightness of an Evo panel (heating problem?). On the other hand, these screens do indeed include the other key elements of the Evo 2024 label, for example the latest version of the Alpha 9 processor, Gen 7.
This Oled Evo panel benefits from Brightness Booster technology and not Brightness Booster Max as on LG G4/M4 TVs. This distinction in the name indicates the absence of a heat sink (therefore no aluminum plate to cool the organic diodes).
LG C4 Oled TV, what diagonals?££££
The LG C4 Oled TV series has six references for as many diagonals, exactly like the LG C3 in 2023: LG OLED42C4 (42'', 107 cm) , LG OLED48C4 (48'', 122 cm), LG OLED55C4 (55'', 140 cm), LG OLED65C4 (65'', 165 cm), LG OLED77C4 (77'', 196 cm) and LG OLED83C4 (83' ', 211 cm). Precision, as for the LG M4 series, the 97'' model does not have Brightness Booster Max technology (Oled Meta).
Oled TV LG C4, Alpha 9££££
We find on LG C4 televisions the chip of the LG C3 references, i.e. Alpha 9. However, the latter in Gen 7 version benefits from some significant developments by the Alpha 11, for example the Dynamic Tone Mapping Pro, Dynamic Sound Booster, AI Clear Sound processes (without the Voice Remastering mode to improve the clarity of dialogue). Likewise, AI Super Upscaling processing replaces AI Upscaling with new algorithms (Frame + Object Detection Upscaling). Virtual Surround sound reproduction remains identical to that of 2023 TVs, in 9.1.2.
LG C4 Oled TV, main specifications££££
For the rest of the specifications, the LG C4 Oled televisions integrate the new WebOS interface which will be updated for the next four years (see our news CES 24 > LG WebOS Re:New function, 4 years of updates guaranteed), 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 144 Hz Oled panel with 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 C4 TVs will benefit from a preview of VRR G-Sync 144 Hz certification in addition to AMD FreeSync Premium. Namely, LG C4 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%.
Wowcast certified LG C4 Oled TV ££££
In 2024, LG is introducing the Wowcast function into its C4 televisions and many of its soundbars. This allows a wireless connection between a TV and a suitable soundbar (see our CES 24 news > 10 LG soundbars: LG S95TR, LG S90TY, LG SG10T, LG S77TY, LG S70TR, LG S70TY, LG S60TR, LG S60T and LG S40T/S20T…) capable of transferring a Lossless Dolby Atmos or DTS:X signal, a first.
Oled TV C4, ThinQ AI Smart TV ££££
The LG OLED C4 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 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.
LG C4 Oled TV, and the rest?££££
For the rest, we find on LG C4 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, 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 C4 Oled TV, HDMI 2.1/HDCP 2.3££££
The connectivity of the LG C4 screens finally brings together four HDCP 2.3 certified HDMI CEC 2.1 inputs, including one with the eARC function. 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.
