#1 Price

LG B4

LG B OLED TV series is known to be the entry-level product line, so the price should be more affordable. The B4 retails at $1,700 for its 55-inch model, $2,200 for its 65-inch model, and $3,400 for its 77-inch model.

The LG C4, on the other hand, is in the mid-price range and is more expensive than the LG B4. The 55-inch model costs $2,000, the 65-inch model costs $2,700, the 77-inch model costs $3,700. However, the C4 is also available in 42-inch and 48-inch sizes, which cost $1,500 and $1,600 respectively, a more affordable price point for those looking for a smaller screen size.

#2 Design

LG C4

Both TVs look sleek and modern with thin bezels and a minimalist design. When not in use, you can display artwork or photos on both TVs to make them blend in with your home decor.

One noticeable difference between the two is the number of ports both TVs offer. While the LG B4 offers 4 HDMI and 2 USB ports, the C4 provides 4 HDMI and 3 USB ports. A higher number of USB ports can be useful for connecting multiple devices such as external hard drives, gaming controllers, and more. This way, you don't have to keep switching devices every time you want to use them.

#3 Picture Quality

LG B4

LG B4 and C4 boast a high level of picture quality, thanks to their OLED technology, high display resolution of 4K UHD, and high native refresh rate of 120Hz. Both TVs are also equipped with features that allow for cinema-like picture quality, such as HDR, Dolby Vision, FIlmmaker Mode, and more.

However, both TVs are powered by different processors, which in turn affects their picture quality. The C4 model has a more advanced Alpha 9 Gen 7 AI Processor compared to the B4 model with the Alpha 8 AI Processor. This makes the C4 capable of producing a more refined picture quality with better color accuracy and deeper blacks.

Additionally, the Alpha 9 Gen 7 AI chip is also better than the Alpha 8 AI chip at upscaling lower-resolution content. This means, if you're watching something that is not in 4K, the LG C4 will be able to upscale it better than the LG B4, resulting in a clearer and more detailed image.

#4 Sound Quality

LG C4

Both OLED TVs deliver a good audio experience. They are equipped with features that allow for immersive sound, such as Dolby Atmos, which creates a 3D audio effect, and AI Sound Pro, which creates a virtual 9.1.2. surround sound to have you feel like you're in the middle of the action, even without external speakers.

But if you have external speakers or a soundbar you want to connect to your TV, both TVs offer LG Sound Sync and Bluetooth Surround Ready features to make it easy to connect and enjoy your favorite audio content.

Despite the common audio features they have, both TVs also have at least one difference. The C4 is equipped with a 2.2-channel speaker system which consists of two speakers and two subwoofers, while the B4 has a 2.0-channel speaker system with only two speakers. With this difference, the C4 is able to produce a more powerful and dynamic sound compared to the B4.

#5 Smart Features

webOS 24

Both OLED TVs run on LG's webOS 24, which is a user-friendly interface that allows for easy navigation and access to popular streaming services like Netflix, Amazon Prime Video, and Hulu. The webOS 24 also allows for up to 10 user profiles, providing personalized recommendations and content based on individual preferences.

Both TVs are also equipped with a range of smart features that allow for convenience, such as voice control, intelligent voice recognition, MultiView, sports alerts, Magic Remote, and many others. You can also connect both TVs to third-party services like Amazon Alexa, Google Assistant, Apple HomeKit, and Apple Airplay 2.

LG B4 vs C4

Just like the other LG's 2024 OLED TV lineup, the B4 and C4 also add new support for Matter, the smart home connectivity standard that allows smart home devices to work together seamlessly, regardless of the brand. This means, you can have your B4 or C4 TV to become a smart home hub to manage and control all of your Matter-compatible smart home devices.

When it comes to smart TV features, the main difference between the two models concerns the Room to Room Share feature. This feature allows you to share content across different LG TVs in your home. The difference is while the C4 can act as both sender and receiver, the B4 can only act as a receiver.

#6 Gaming Support

LG B4 vs C4

On top of their exhaustive list of smart TV features, both the B4 and C4 are also loaded with gaming features that make them ideal for gamers, including LG Game Dashboard, Game Optimizer, Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), NVIDIA G-Sync, and AMD FreeSync Premium.

The C4 has a slight advantage with its support for a higher refresh rate of 144Hz, while the B4 supports a maximum refresh rate of 120Hz. A higher refresh rate can provide a smoother and more responsive gaming experience, especially for fast-paced games. However, keep in mind that for now, gaming consoles such as the PS5 and Xbox Series X can only output up to 120Hz. The potential advantage of the C4's higher refresh rate may not be fully utilized unless you own a premium gaming PC that has a 144Hz graphic card.
