I had the opportunity to test this product for a few weeks (without paying), and here is my experience:
The LG Evo C4, despite minimal changes from the previous model, still delivers the familiar high quality of LG’s OLED TVs. The picture quality is impressive, with improved brightness, color reproduction and shadows. The refresh rate has been increased to 144Hz, which will appeal to PC gamers in particular. The viewing angles are excellent, even at extreme angles, although some users report a greenish tint—I didn’t experience this myself. One thing this model misses is the MLA technology, which could have provided a higher brightness.
As for the sound, the quality is reasonable for TV speakers, although you will notice, especially at lower tones, that a soundbar or external speakers would improve the sound considerably. The TV is solidly built, with a metal front and a plastic back, where the ports are also located. The back of the panel has a stylish black-marble finish. The TV has four HDMI 2.1 ports, three USB 2.0 ports and an Ethernet connection.
The WebOS operating system offers a comprehensive feature set, with many picture quality settings and support for Dolby Vision, AirPlay, Miracast, Nvidia G-Sync and AMD FreeSync. You can control the TV with the remote control, voice, or by making gestures on the remote control, similar to a Wii. A downside of WebOS is the prominence of advertisements and AI features, which somewhat diminishes the user experience, especially considering the price range of this TV.
While the LG C4 is a good choice, the G3 and even the C3 currently offer better value for money. The G3 has better picture quality, a lower price and a 5-year warranty on the panel. The C3 offers similar performance for a considerably lower price. In summary: the C4 is a solid TV, but is currently overshadowed in terms of price and features by the C3 and G3.
