LG C3 vs. Samsung S90C: A Quick Look

Both the LG C3 and the Samsung S90C are fantastic OLED televisions. This means they offer incredible contrast, perfect black levels, and vibrant colors. However, they achieve this through slightly different technologies, leading to some key differences in performance. Understanding these distinctions will help you decide which one is the perfect fit for your living room.

What are OLED TVs?

Before we dive into the specifics, let’s quickly touch on what makes OLED TVs so special. OLED stands for Organic Light-Emitting Diode. Unlike traditional LED TVs that use a backlight to illuminate pixels, each pixel in an OLED TV is its own light source. This revolutionary approach allows individual pixels to turn on or off completely, leading to:

• Perfect Black Levels: When a pixel is off, it emits no light, creating true black that you can’t achieve with other TV technologies.
• Infinite Contrast Ratio: The difference between the brightest white and the darkest black is theoretically infinite, leading to incredibly realistic images.
• Wider Viewing Angles: Colors and contrast remain consistent even when viewed from the side.
• Faster Pixel Response Times: Pixels can change color and brightness almost instantaneously, which is great for fast-moving scenes.

Now that we know what the core technology offers, let’s see how the LG C3 and Samsung S90C stack up against each other in 2025.

Picture Quality Deep Dive: Brightness, Color, and Contrast

Let’s get a little more specific about what makes these TVs look so good.

Brightness

For OLEDs, brightness is often a critical factor, especially for daytime viewing or very bright rooms. The LG C3, with its ‘Brightness Booster’ technology, is designed to push its OLED panels to deliver more light output, particularly in brighter scenes and HDR highlights. This translates to a picture that can better combat glare and appear more dynamic in well-lit environments.

The Samsung S90C, on the other hand, uses QD-OLED technology. This means it uses Quantum Dots to enhance the light emitted by the OLED pixels, leading to incredibly vibrant colors. While this also contributes to brightness, especially for colored highlights, its overall peak brightness in standard content might be slightly more conservative than the absolute brightest LG models in certain scenarios. However, for HDR content, both TVs are exceptionally bright and capable.

Color

This is where the Samsung S90C truly shines. The integration of Quantum Dots into its QD-OLED panel allows for an exceptional color volume. What this means is that the S90C can display a wider range of colors, and crucially, it can do so at higher brightness levels. This results in colors that appear more saturated, lifelike, and impactful, especially in high-dynamic range content.

The LG C3 (using WRGB OLED technology) offers excellent color reproduction with wide color gamut coverage. Its colors are natural and accurate. However, when you compare the sheer vibrancy and punch of colors at peak brightness, the S90C’s QD-OLED technology often gives it an edge. For many, this difference is the deciding factor.

Contrast and Black Levels

This is an area where all OLEDs, including the C3 and S90C, excel. The fundamental nature of OLED technology, where each pixel generates its own light, means that pixels can be turned off completely. This results in what we call “infinite contrast ratio” and “perfect black levels.”

Both the LG C3 and the Samsung S90C will deliver absolute blacks. What this means for you is that dark scenes in movies will look phenomenally deep and detailed, with no distracting gray tints. The distinction between the darkest shadows and the brightest highlights is incredible, creating an immersive viewing experience that is a hallmark of OLED technology.

When it comes to contrast, the S90C’s QD-OLED might have a slight theoretical edge due to its ability to produce brighter colors alongside those perfect blacks, but in practice, both are absolutely stunning. For the average viewer, the difference in black levels and contrast between these two exceptional TVs will be virtually imperceptible.

Gaming: A Battle of Titans

For gamers, both the LG C3 and Samsung S90C are fantastic choices, packing all the latest features to ensure a smooth and responsive experience. However, there are subtle differences that might tip the scales for certain gamers.

Key Gaming Features

• 4K 120Hz Support: Both TVs can display content at a resolution of 4000 pixels and a refresh rate of 120 times per second. This is essential for next-gen consoles like the PlayStation 5 and Xbox Series X.
• Variable Refresh Rate (VRR): This technology synchronizes the TV’s refresh rate with the console’s frame rate, preventing screen tearing and stuttering. Both support this.
• Auto Low Latency Mode (ALLM): When ALLM is enabled, the TV automatically switches to a game mode with minimal input lag when it detects a game console is connected.
• HDMI 2.1 Ports: Both TVs feature multiple HDMI 2.1 ports, which are necessary to take full advantage of 4K 120Hz and other advanced gaming features. The LG C3 typically offers four full HDMI 2.1 ports, while the S90C also provides them.

Where They Differ in Gaming

Motion Handling: As mentioned, LG often has a slight edge in motion clarity due to its processing. This means fast-paced action games might appear a tad sharper on the C3. This is less about input lag and more about how quickly the pixels can change and how well the TV interpolates frames.

Input Lag: Both TVs offer exceptionally low input lag, meaning your button presses register almost instantaneously on screen. For the vast majority of gamers, the difference in input lag between the C3 and S90C will be negligible.

Brightness for Gaming: If you game in a very bright room, the C3’s slightly higher generally brightness might be beneficial. However, the S90C’s vibrant colors can make games incredibly immersive, especially in darker environments.

Smart TV Platforms: WebOS vs. Tizen

The smart TV platform is your gateway to streaming services, apps, and TV settings. Both LG’s WebOS and Samsung’s Tizen are mature, capable operating systems, but they have different looks and feels.
