Picture Quality

The LG C7P OLED reigns supreme when it comes to picture quality:

  • Perfect Blacks: Thanks to OLED (Organic Light-Emitting Diode) technology, each pixel can completely turn off, resulting in true blacks. This unmatched ability to display inky blacks creates a stunning contrast ratio, making dark scenes appear more detailed and lifelike. Compared to LED TVs, which rely on backlighting, OLED eliminates the issue of “light bleed” for a truly immersive viewing experience.

  • Vibrant Colors and Wide Color Gamut: The C7P boasts exceptional color accuracy and a wide color gamut, exceeding traditional Rec. 709 standards. This translates to a wider spectrum of colors, making visuals appear richer, more lifelike, and bursting with vibrancy. Whether you’re watching a nature documentary or a visually stunning film, the C7P delivers a breathtaking color palette.

  • HDR (High Dynamic Range) Support: Dive deeper into the world of HDR. The C7P supports HDR formats like HDR10 and Dolby Vision. This unlocks a wider range of colors and brightness, creating highlights that appear incredibly vivid and shadows that hold significant detail. HDR content truly comes alive on the C7P, offering a more dynamic and realistic viewing experience.

  • Superior Motion Handling: Fast-paced content appears smooth and clear on the C7P. The TV utilizes LG’s advanced processing technology to minimize judder (a stuttery effect) and motion blur. This is particularly beneficial for sports fans, gamers, and anyone who enjoys action movies.

The LG C7P embraces a minimalist design that remains stylish even by today’s standards. The bezels are thin, creating a near bezel-less look that allows the picture to take center stage. The sleek and modern design complements most living room aesthetics without appearing bulky or outdated.

The TV utilizes a sturdy metal stand that provides excellent stability, ensuring your C7P stays securely in place. While newer models might boast even thinner profiles or more premium materials, the C7P’s design holds its own and prioritizes functionality without sacrificing aesthetics.

Standing the Test of Time: How the C7P Compares to Modern TVs

While the LG C7P is a few years old, it still holds its own against some modern offerings. Here’s a breakdown:

  • Newer OLED TVs: Newer LG OLED models, like the C1 and G1 series, boast advancements in processing power, potentially offering slightly better motion handling and upscaling capabilities for non-4K content. However, the core picture quality strengths of perfect blacks, vibrant colors, and HDR support remain exceptional on the C7P.

  • High-End LED TVs: High-end LED TVs from reputable brands might offer similar brightness levels to the C7P. However, they cannot achieve the perfect blacks and contrast ratio that OLED technology delivers. For viewers prioritizing the ultimate dark room viewing experience, the C7P remains a compelling option.

Brightness and Contrast

As mentioned earlier, the LG C7P’s OLED technology shines (or should we say, doesn’t shine) when it comes to brightness and contrast. Here’s what you need to know:

  • Perfect Blacks and Infinite Contrast: OLED’s ability to completely turn off pixels results in perfect blacks and an infinite contrast ratio. This is a major advantage for dark room viewing, as scenes appear incredibly detailed and immersive.

  • Decent Brightness for Most Environments: While some newer OLED TVs boast slightly higher peak brightness levels, the C7P delivers good brightness that’s suitable for most living room environments. However, if your living room receives a lot of natural light, a very bright TV might be a better choice.

Sound Quality

The built-in speakers on the LG C7P deliver a decent audio experience for casual viewing. Dialogue is clear, but the overall sound can feel a bit thin and lack the depth and power needed for a truly immersive cinematic experience. This is a common limitation with most TVs, especially thin OLED models.

To elevate your audio experience, especially for movie nights or music listening, investing in a soundbar or a surround sound system is highly recommended. This will provide a more robust and immersive soundscape, doing justice to the C7P’s exceptional picture quality.

Smart Features

While the webOS platform on the C7P isn’t the most cutting-edge compared to the latest TVs, it still offers core functionalities:

  • Popular Streaming Services: Access a vast library of popular streaming services like Netflix, Hulu, YouTube, and others. This ensures you have plenty of content to choose from, catering to diverse viewing interests.
  • Voice Control: Control your TV with your voice! The C7P integrates voice control capabilities, allowing you to search for content, control playback, and adjust TV settings using your voice. This adds a layer of convenience to your viewing experience.


The LG C7P boasts excellent motion handling thanks to its advanced processing technology. Here’s what you can expect:

  • Smooth and Clear Fast-Paced Scenes: Fast-paced content like sports, action movies, and fast-moving video games appear smooth and clear with minimal judder (a stuttery effect) and motion blur. This creates a more enjoyable viewing experience, especially for content with a lot of movement.

  • OLED Advantage: OLED technology inherently contributes to smooth motion handling. Since each pixel can turn on and off incredibly fast, there’s minimal image persistence or trailing effects, further enhancing motion clarity.

Gaming Features

The LG C7P caters to casual gamers with features that enhance gameplay:

  • Low Input Lag: Gamers prioritize responsiveness. The C7P delivers low input lag, minimizing the delay between your controller input and what appears on the screen. This is crucial for fast-paced games where reaction time is critical.

  • G-Sync and FreeSync Compatibility (on select models): Some C7P models, depending on the specific model year, might offer compatibility with G-Sync and FreeSync technologies. These technologies help synchronize the refresh rate of the TV with the frame rate of your compatible gaming console or PC. This can further improve smoothness and eliminate screen tearing, creating a more responsive and enjoyable gaming experience.

Durability and Build Quality

The LG C7P OLED TV is known for its excellent build quality:

  • Sturdy Metal Stand: The TV utilizes a sturdy metal stand that provides excellent stability, ensuring your C7P stays securely in place. This is important for preventing accidental tip-overs or wobbly screens.

  • Well-Built Design: The overall build quality feels solid and reliable. With proper care, a pre-owned C7P has the potential to last for many years. While some newer models might boast even thinner profiles, the C7P prioritizes functionality and durability.

Viewing Angles and Screen Uniformity

The LG C7P OLED TV offers excellent viewing angles:

  • Wide Viewing Range: Unlike some LED TVs where picture quality can deteriorate significantly when viewed from off-axis angles, the C7P maintains a consistent picture quality even when viewed from the side. This makes it suitable for living rooms where viewers might not be seated directly in front of the TV.

  • Excellent Screen Uniformity: OLED technology generally delivers exceptional screen uniformity. This means that brightness, color, and contrast remain consistent across the entire screen, minimizing any distracting variations.


The LG C7P offers a good selection of inputs, including:

  • 4x HDMI ports (all support HDCP 2.2)
  • 3x USB ports for media playback or connecting external devices
  • Optical digital audio output
  • Ethernet port for wired internet connection

This selection caters to most viewers’ needs. You can connect various devices like streaming sticks, gaming consoles, Blu-ray players, and external hard drives without any limitations. The HDMI ports support HDCP 2.2, ensuring compatibility with the latest 4K HDR content.

Overall Value

The LG C7P OLED TV offers a compelling value proposition for viewers seeking exceptional picture quality at a potentially attractive pre-owned price point. Here’s a quick recap:

  • Strengths: Perfect blacks for unmatched contrast, vibrant colors and wide color gamut, HDR support for a more dynamic picture, superior motion handling, sleek and timeless design, decent brightness for most environments, user-friendly smart platform with voice control, low input lag for gamers (consider models with G-Sync/FreeSync compatibility), good build quality, wide viewing angles, excellent screen uniformity, and a variety of input options.

  • Considerations: Brightness might not be ideal for very bright rooms, built-in speakers might not be powerful enough for immersive audio experiences, smart platform not the most cutting-edge compared to modern TVs.

The Final Verdict

By considering your needs and priorities, you can decide if the LG C7P OLED TV deserves a spot in your home theater. Here are some additional thoughts:

  • For Value-Conscious Viewers: If exceptional picture quality is your top priority and you’re open to exploring the pre-owned market, the C7P offers a potentially significant cost saving compared to a brand new high-end TV.

  • A Dark Room Powerhouse: For viewers who prioritize dark room viewing experiences, the C7P’s perfect blacks and unmatched contrast remain a major advantage.

  • Future-Proof Considerations: While the smart platform might not be the most cutting-edge, most viewers can connect a streaming stick or smart device for an updated smart TV experience.


The LG C7P OLED TV stands as a testament to timeless design and exceptional picture quality. While newer models offer advancements, the C7P remains a relevant option for viewers seeking a high-performance OLED TV at a potentially attractive pre-owned price point. By understanding its strengths, considerations, and how it compares to modern offerings, you can make an informed decision about whether this legendary LG OLED TV deserves a place in your home entertainment setup.
