The LG M4 Evo Oled TV series offers broadcasters equipped with a remote wireless box (the black box present on the marble support at the bottom right in the photo at the bottom of this news) bringing together all the connectors and a part of electronics. This configuration is called Zero Connect technology by LG. This makes it easy to place the screen wherever you want in a room without any layout constraints. The transfer of audio-video signals is ensured wirelessly up to Ultra HD 4K HDR Dolby Vision 144 Hz and Dolby Atmos/DTS:X.
Oled TV LG M4 and Peak Highlighter, +150% Vs LG B4
The peak light of LG M4 TVs is announced to be equivalent to +150% of that of LG B4 references. It should be noted that, apart from this value, and unlike last year, the brand does not give a figure “in nits†for the peak light of M4 screens. Assuming that the performance of the Oled panels of the LG B4 screens remains more or less similar to that of the LG B3 on the one hand, and that the peak of the LG M4 is +150% brighter than the LG B4, i.e. twice as much than the LG M3 vintage 2023 (+70% and 2,100 nits as a reminder) on the other hand, this should logically be significantly higher in 2024.
Indeed, to be clear, the value put forward by the brand gives a light peak of LG M4 TVs 2.5x greater than that of LG B4 TVs. We will nevertheless wait for LG to specify this peak in nits to mention it rather than putting forward a random figure. Precision, the peak light of LG M4 TV at +150% compared to LG B4 TVs, thanks to the function called Peak Highlighter, is measured for an APL of 3% (window of white occupying 3% of the surface area of the screen ). Interesting for giving even more pep to reflections or specular lights for example (a starry sky, the reflection of the sun on a windshield or an aluminum bumper, etc.).
Oled TV LG M4 and Highlighter Color, always vibrant colors
In addition to the new Peak Highlighter function, LG M4 Oled televisions also offer the Highlighter Color function for always rich colors even in bright areas of the image. With the latter, LG wants to remedy one of the main defects of White Oled technology, a fading of colors associated with the light peak. The reason is simple, to obtain a significant light peak, the white sub-pixel is used more and takes precedence over the other RGB sub-pixels.
Oled TV LG M4, Brightness Booster Max and MLA
As a reminder, the Brightness Booster Max mode appearing in 2023 on the LG G3/M3 series relies heavily on the MLA process (for Metal Illuminated Lens Array). The latter lies in the addition of micro-lenses to the Oled TV panel, the purpose of which is to optimize the path of the light generated by the diodes, to direct it entirely outwards, i.e. on the panel side. Thus, if leaving the factory a classic Oled panel displays a light peak of around 800 nits and an Oled EX around 1,000 nits, a panel equipped with micro-lenses would reach 2,100 nits in 2023, says LG Display (we repeat , anxious not to be mistaken, we are waiting for the brand to specify the figure “in nits†for the 2024 light peak on the LG G4/M4 TV series to relay it). Another positive point is that this better light efficiency also has an impact on energy efficiency, which is again improving, for lower final consumption. Of course, as in 2022 and 2023, the Max suffix also indicates the presence of a heat sink to cool the organic diodes which are very sensitive to heat.
Oled TV LG M4, what diagonals?
The LG M4 Oled TV series has four references for as many diagonals, one more than in 2023. The LG OLED65M4 (65'', 165 cm) complements the LG OLED77M4 (77'', 196 cm), LG OLED83M4 (83'', 211 cm) and LG OLED97M4 (97'', 246 cm). Please note, if the 83'' model benefits from Brightness Booster Max (Oled Meta) technology in 2024 unlike 2023, the 97'' model does not, like its counterpart last year.
Oled TV LG M4, Alpha 11
The new chip present in LG M4 Oled TVs is not called Alpha 10 (see our LG Oled 2024 TV news, powerful Alpha 10 processor on the menu), as predicted by the Korean press last school year, but Alpha 11. Its power, according to LG, is much higher than that of the Alpha 9: 4x higher artificial intelligence performance, 1.7x higher graphics performance, 1.3x higher noise power and 2.5 gigabytes of RAM.
The latter includes the Dynamic Tone Mapping Oled Pro, Dynamic Sound Booster, AI Clear Sound (with Voice Remastering mode to improve the clarity of dialogue) and Virtual Surround 11.1.2 processes. Likewise, AI Super Upscaling processing replaces AI Upscaling with many improvements (Pixel Detection Upscaling + Visual Detection, Frame + Object Detection Upscaling). We can also cite the AI Directors Processing functionality (to respect the tone of the image desired by the director or the DoP).
LG M4 Oled TV, main specifications
For the rest of the specifications, LG M4 Oled 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 144 Hz Oled panel (except for the 97'', capped at 120 Hz), 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 M4 TVs will benefit from a preview of VRR G-Sync 144 Hz certification (except of course the 97'') in addition to AMD FreeSync Premium. Namely, LG M4 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%.
Oled TV LG M4 certified Wowcast
In 2024, LG will introduce the Wowcast function into its M4 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 M4, Smart TV ThinQ AI
The LG OLED M4 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 modeâ€, 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 M4, and the rest?
For the rest, we find on LG M4 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 M4 Oled TV, HDMI 2.1/HDCP 2.3
The connectivity of the LG M4 screens brings together three HDCP 2.3 certified HDMI CEC 2.1 inputs on the remote box, including one with the eARC function. There is also an optical output, plus two USB Host ports, an antenna socket and an Ethernet port. A CI+ port is also present on the television. In addition to VP9 and AV1, MP3, AAC, PCM, WMA, VC-1 and Jpeg compatibility are ensured, with the MKV container.
Finally, LG M4 televisions benefit from the 5-year Oled Premium warranty ensuring a standard exchange of the panel in the event of a problem. More details at the CES show in Las Vegas next week.
Namely, except for the photo below, the photos in this news are those of the 2023 vintage LG Oled TVs, pending the good visuals provided by the brand.
Availability and indicative prices still unknown.
