The LG G5 TV series (55", 65", 77", 83" and 97", see photo below) and LG M5 (65", 77", 83" and 97", identical models in terms of technical characteristics to the LG G5, but equipped with a Zero Connect Box wireless box ensuring the transfer of audio-video signals to the TV, see photo above) therefore say goodbye to Meta technology (with MLA process for Micro Lens Array or microlenses) and hello (except the 97") to new Oled panels equipped with Brightness Booster Ultimate technology (for a suspected peak brightness of 4,000 nits while waiting for a communication from LG Display, see our news (UPDATE) CES 25 > LG G5 Oled TV: 4,000 nits target). At the same time, they say hello to the new Tandem Oled panels equipped with Brightness Booster Ultimate technology for a (still unofficial) peak brightness of 4,000 nits.
Primary RGB Tandem panel, four layers of Oled emitting materials££££
Behind the name Tandem Oled RGB hides a new Oled panel structure made up of four layers of organic emitting materials including two layers of blue materials. Surprise, the composition of these layers would not ultimately be the one announced at the beginning of January during the presentation of this new technology at the CES show in Las Vegas 2025. LG Display's recent statement on this subject contradicts the information gathered on site (see our CES 25 news > Primary RGB Tandem Oled panel 4,000 nits, have we been lied to?), the blue emitting elements being (late) announced still of the fluorescent type and not phosphorescent. The combination of these two blue emitters, mixed with the other red and green phosphorescent organic emitting materials with deuterium sauce (a material already used since the appearance of Oled EX panels in 2022), refines the wavelength of light and improves the purity of colors to offer increased performance in terms of brightness but also color volume. LG Display has continued to perfect this last point, an intrinsic weakness of White Oled technology. We can't wait to judge the brand's claims for themselves.
Another advantage highlighted by Tandem Oled RGB technology is a reduced risk of marking (pixel burn-in). Again, this is a point that LG Display has been working hard on since the beginning of Oled technology. And while significant progress has been made in recent years, the problem persists during specific use (long video game sessions or broadcasting a news channel with a banner at the bottom of the screen, for example). The Tandem Oled process would be the most significant advance on the subject since the launch of Oled.
Ultimately, thanks to Tandem Oled RGB technology, the peak brightness of LG G5 and LG M5 TVs is three times greater than that of LG B5 TVs (Editor's note: for a 10% APL). Another figure, the LG G5 and LG M5 diffusers offer for a 100% APL (i.e. a completely white screen) a brightness of +40% compared to the LG G4 models from the 2024 vintage: we can therefore hope for a measurement close to 300 nits. All this is set to music by the new Alpha 11 Gen 2 central processor.
Namely, the LG G5 series welcomes in 2025 the 48" (122 cm) 144 Hz diagonal but the latter does not benefit from the Brightness Booster Ultimate function. Similarly, the LG OLED97G5 Evo reference does not offer the performance of the LG G5 55", 65", 77" and 83" in terms of brightness. The same goes for the LG OLED97M5 compared to the LG M5 65", 77" and 83 inches.
LG G5/M5 Evo Oled TV, UL Intertek certifications££££
Another evolution of the LG G5/LG M5 Evo televisions, the UL Intertek Perfect Black Technology and Perfect Color Technology certifications for an environment up to 500 lux. The first guarantees a black level of less than 0.24 nit up to an ambient brightness of 500 lux; the second of the colors constant up to 500 lux as well.
Clarification on LG G5 televisions (except the 97" model), if the latter are compatible with 165 Hz (see our CES 25 news > LG G5 Oled TV, PC gaming objective with Vesa 165 Hz certification) and certified FreeSync Premium/G-Sync, the [abc]VRR[/abc] will not be available in [abc]HDR Dolby Vision[/abc]/165 hertz.
