The LG 77C5 is the 77 inch version of the LG 77C5 that we tested. Apart from their size, their characteristics are therefore identical. You will find a summary of our test below, but we recommend reading our full 65C5 test to find out more:
SDR and HDR image quality
The LG 77C5 TV retains the fundamentals of the C series with an OLED EVO slab which guarantees infinite contrast and very precise colorimetry, especially in FilmMaker mode where the Delta E is measured at 1.2. SDR content benefit from excellent fidelity with natural colors. In HDR, the TV supports the Dolby Vision, HDR10 and HLG standards, and reaches a light peak of 1150 CD/m², in improvement compared to the C4, although still behind in front of the LG G5 and the best mini-LEDs such as the TCL C89B or the Hisense U8NQ. The absence of clouding and blooming And an average reflectance of 25.9 % confirm a very solid visual service, even if the anti -reflective could be more efficient.
Video game
The LG 77C5 is distinguished as an excellent choice for players with a input lag Very low (13 ms, or even 9.2 ms with the enabled reinforcing mode), an almost instantaneous response time (0.1 ms) and full HDMI 2.1: 4K at 144 Hz, VRR, Allm, Freesync and G-Sync. The television offers an intuitive gamebar to adjust the parameters in the game. On the other hand, the colorimetry in SDR in the game mode is disappointing (Delta E of 6.4), although an improvement is possible in HDR by adjusting the settings, which makes it possible to reduce the Delta E to 2,3.
Audio, ergonomics and consumption
The design of the LG 77C5 evolves little, but remains elegant and well finished with a complete connectors and a new more modern remote control, although always without backlight. The webos interface remains fluid, customizable and enriched with some IA features. On the sound side, the integrated system offers convincing performance with clear voices and a good presence of bass, even if a sound bar remains recommended for an optimal rendering. In terms of consumption, the TV has remarkable energy efficiency with 65.8 W/m². Repairability is correct (7.3/10) and several functions aim to prevent burn-instrengthen the sustainability of the device.
