LG C3 & LG B4 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the LG C3 rather than the LG B4.
Why Do I Recommend The LG C3?
- The LG C3 has an advanced α9 AI Processor Gen6 for faster image processing, sharper upscaling, and smoother motion handling compared to the LG B4’s α7 Gen6 chip.
- LG C3 includes Brightness Booster technology for achieving higher peak brightness, which improves HDR highlights and visibility in bright room conditions compared to the LG B4.
- It supports 4 HDMI 2.1 ports for full-speed connections to multiple next-gen gaming consoles and devices, while the LG B4 is limited to only 2 HDMI 2.1 ports.
- The LG C3 features NVIDIA G-SYNC and AMD FreeSync Premium for reducing screen tearing and stutter during gaming, compared to the LG B4’s standard VRR support.
- LG C3 comes with a 2.2 channel 40W speaker system for more immersive sound output, especially for dialogue and bass, compared to the LG B4’s 2.0 channel 20W system.
- It supports AI Picture Pro and AI Sound Pro for dynamically optimizing visuals and audio based on scene detection, compared to the LG B4.
- The LG C3 includes Dolby Vision Gaming at 4K 120Hz for smoother and more vivid gameplay with compatible consoles, whereas the LG B4 is limited to lower refresh rates.
- LG C3 features a premium ultra-slim aluminum frame design for enhancing the aesthetic appeal and reducing bulk on the wall, compared to the thicker plastic-framed LG B4.
Maybe the LG B4 price can make you comfortable because it’s a little bit cheaper than the LG C3. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
