In the world of TVs, OLED technology has taken center stage, offering stunning picture quality and vibrant colors. LG, a leading brand in the industry, introduced two new TVs to its popular G-series and C-series in the spring of last year; the LG C3 OLED and LG G3 OLED. These products built on the successes of their respective predecessors, as well as incorporated new features that were well received by users. Each of these TVs has unique functions and specifications making it essential to understand the differences between them before making a purchase decision. This article will cover everything you need to know about these devices; drawing a comparasion between the LG C3 OLED vs LG G3 OLED.

Let’s jump right in!

LG C3 OLED vs LG G3 OLED – Comparison


When it comes to design, the LG G3 OLED truly stands out. It features a sleek and modern design with a no-gap wall mount. Unlike previous models, the G3 OLED sits against the wall; providing a seamless look and setting it apart from other TVs like the C3 OLED, which comes with a regular stand (included with the TV). This is a really exciting feature of the G3 and something to consider if you’re someone who prioritizes design. However, it is important to note that the wall mount for the G3 OLED is sold separately as an optional accessory – meaning you would have to spend more money to access the full potential of this TV.

Screen sizes

In terms of screen sizes, the LG C3 OLED offers a wider range of options. Last year’s C2 model was available in five sizes: 55-inch, 65-inch, 77-inch, 83-inch, and 97-inch. In addition to these sizes, the C3 OLED has also introduced a 48-inch and 42-inch option. However, the LG G3 OLED only offers four sizes: 55-inch, 65-inch, 77-inch, and 83-inch. Making the C3 a more versatile choice for those looking for a specific screen size.


Performance is a crucial aspect to consider when choosing between the LG C3 OLED and the LG G3 OLED. With LG’s new Brightness Booster Max technology, which combines the Alpha a9 Gen 6 Processor and lighting algorithm changes, the G3 OLED offers a 70% increase in brightness compared to older OLED TVs. This enhanced brightness results in more vibrant colors and improved visibility in rooms with ambient light.

Both the C3 OLED and the G3 OLED share the same processor, ensuring similar upscaling and motion processing capabilities. As each pixel on an OLED TV produces its own light, there are no concerns about blooming. However, it’s worth noting that the G3 OLED feels like a substantial upgrade from its predecessor, while the C3 OLED offers a more modest improvement over its previous generation.

Connectivity options

Both the LG C3 OLED and the LG G3 OLED offer the same number of HDMI 2.1 ports, providing ample connectivity options for various devices. Additionally, both models have the same inputs and outputs. However, the LG G3 OLED has an added advantage with its inclusion of an ATSC 3.0 tuner. This feature allows users to watch NextGen TV, making it a preferred choice for those who prioritize access to the latest broadcasting technology.

LG C3 OLED vs LG G3 OLED – Price

When comparing the LG C3 OLED and the LG G3 OLED, one of the key factors to consider is the price. Generally, the C-Series tends to be more affordable than the G-Series. For instance, the previous generation LG C2 OLED was priced at $1,799 for the 55-inch model, while the LG G2 OLED came in at $2,199.

The LG G3 55-inch model comes at $2,499, while the 55-inch of the LG C3 OLED model comes at $1,899. Making the C3 a substantially cheaper option for those more concerned with budgeting.

Weighing it up

When buying new tech I’m definietly swayed by products on the cheaper end – who isn’t? However, it’s always important to weigh up the differences and try to gauge the benefits you could be getting in the long term out of a more expensive product.

LG C3 OLED vs LG G3 OLED – conclusion

Choosing between the LG C3 OLED and the LG G3 OLED ultimately depends on your budget and preferences. If you’re looking for a cost-effective upgrade and a wider range of screen sizes, the LG C3 OLED is an excellent choice. It offers affordability and versatility, making it suitable for various needs.

However, if you’re willing to invest a bit more for superior picture quality and advanced features, the LG G3 OLED is worth considering. With its increased brightness, flush wall mount design, and ATSC 3.0 tuner, the G3 OLED offers a premium viewing experience.

In all, both the LG C3 OLED and LG G3 OLED are exceptional TVs with outstanding features – so either way you decide to go will be a worthwhile purchase.
