    Outstanding Picture Quality and Immersive Experien

    I recently purchased the LG C4 OLED TV, and I have to say, it has completely exceeded my expectations. The picture quality is nothing short of stunning, with the deep blacks, vibrant colors, and incredible contrast that OLED technology is known for. Watching content on this TV feels like you're stepping into a whole new world – the clarity and detail are mesmerizing, and the picture is always perfectly crisp, even in dark scenes. The design of the LG C4 is sleek and modern, fitting seamlessly into my living room. The thin profile makes it look incredibly stylish, and the stand is sturdy yet elegant. It's clear that a lot of thought went into the build quality, making it a beautiful addition to any space. One of my favorite features is the vibrant color accuracy. Whether I’m watching movies, gaming, or just browsing through regular TV shows, the colors pop in a natural, lifelike way. The brightness level is excellent too, ensuring that you get a great viewing experience even in well-lit rooms. Speaking of gaming, the LG C4 OLED TV shines here as well. The 120Hz refresh rate and support for HDMI 2.1 make it perfect for next-gen gaming consoles, offering ultra-smooth gameplay and reduced input lag. Whether you’re playing fast-paced shooters or open-world games, the TV delivers a fluid and immersive experience that really enhances the overall gaming experience. Additionally, the smart features and user interface are intuitive and easy to navigate. The WebOS system is fast and responsive, and I’ve had no issues accessing my favorite apps like Netflix, YouTube, and Disney+. The voice control functionality is also an added bonus for hands-free operation. Overall, the LG C4 OLED TV is a top-of-the-line product that delivers exceptional picture quality, great design, and cutting-edge features. If you're looking for a TV that offers a truly immersive viewing experience, I highly recommend this model. It’s definitely worth the investment!

    Amazing Experience.

    This TV has replaced my monitor for my computer. I can't believe I didn't do this sooner. The visuals produced are incredible. It also displays 120hz (144hz in boost mode which requires HDMI 2.1) which is perfect for my needs. Games look incredible. And using it to watch movies and TV shows is also great. The TV will add more frames to shows and movies so that the picture looks smoother which can be nice for some shows or movies but definitely not all. Overall it's a great TV and I highly recommend!

    Maybe best in size class without breaking the bank

    I've had a C1 (65") as my main tv for several years and I absolutely love it. I decided to upsize my bedroom tv which is primarily used for gaming when aforementioned main screen is otherwise in use as there was a great sale on budget TVs last xmas (I went with a TCL 43" Q6). I thought I'd be fine with a budget tv, but comparing it to the C1 just showed me that it's worth paying for the quality. The C4 has vivid colors, supports both 4k at 120 HZ AND 1440 at 120Hz, making it a perfect gaming display (at least as perfect as you can get without spending a real fortune). Vivid colors, super low latency, and since OLED, perfect blacks. If there's any complaint it's that maybe HDR mode could be a little brighter, but I almost always play in a dark room so for me that's not really a huge issue. The C4 also has shockingly good sound for a modern TV. Audiophiles are still gonna want to use dedicated speakers, but I was pleasantly surprised at how decent it sounded on the occasions I wasn't just using my typical headphones. webOS remains fine. The mouse pointer remote function is as useless as it's always been, and I wish LG would just go directly to Google TV instead, but webOS is quick and responsive and supports pretty much every streaming service I could think of using. Definitely recommended if you want a great tv without getting into the higher end flagship model pricepoints.

    Absolutely Incredible as a Monitor and TV

    I’ve been using the LG C4 42-inch OLED TV as my primary computer monitor for a few weeks now, and all I can say is: wow. This thing is an absolute beast in every way — it has completely transformed my workspace and my gaming setup. First off, the picture quality is jaw-dropping. The OLED panel delivers true blacks, stunning contrast, and vibrant, lifelike colors that make everything pop. Whether I’m editing photos, watching 4K content, or just browsing the web, the clarity and richness of the display are on another level. But where the C4 really shines is gaming. With 4K resolution, 120Hz refresh rate, and HDMI 2.1 support, it’s an absolute dream. Paired with my gaming PC and next-gen console, the gameplay is buttery smooth, incredibly responsive, and visually breathtaking. G-SYNC and FreeSync compatibility also help eliminate screen tearing, making everything feel super fluid. The Game Optimizer mode is a nice touch, giving me quick access to important settings without digging through menus. I also love the 0.1ms response time — it makes fast-paced FPS and racing games feel tight and snappy. The 42-inch size is perfect for a desk setup. It offers all the immersion of a large screen without overwhelming the space, and the pixel density at 4K is excellent even at a close viewing distance. Overall, I couldn’t be happier. If you’re looking for a high-end monitor that can do it all — productivity, media, and especially gaming — the LG C4 is hands-down one of the best choices out there.

    TV for monitor WIN

    After reading reviews and watching a few YouTube videos of this LG C4 as a PC gaming monitor, boy am I impressed! I’ve had ultrawodes 1k, 2ks and this being my first 4k at 42 inches definitely puts immersion on another level! Gsync and 144hz is perfect for 4k and I can’t believe a TV has this! In all 10/10 use it for shooters and adventure games. Browsing the web and documents are easy to read and sharp not blurred which is what I was afraid of. Definitely super happy and sold my other 2 monitors. 42inches as a PC monitor is perfect as 34 or 38 feel big. A 48 inch could have worked as well but I felt it was too big. I would go bigger as it looks amazing for gaming and movies. Best Buy had a nice deal on it too, always buy TVs and big electronics here. Applied and used their financing as well, i appreciate the convinience and made my purchase a no brainer. Thanks BestBuy!

  • Can this television be connected to a roof antenna?

    Hi, Mary. Thank you for your interest. The LG TV (OLED42C4PUA) model doesn't have a built-in coaxial input for a traditional roof antenna, so it can't be directly connected to one without additional equipment. However, you can connect your antenna to an external tuner or a set-top box that has a coaxial input. Then, you can connect the tuner or box to the TV via HDMI for watching over-the-air channels. For more information regarding the product, you may visit https://www.lg.com/us/tvs/lg-oled42c4pua-oled-4k-tv.

  • Does the TV/Monitor have any type of Motion Interpolation or Motion Smoothness features to make 30fps or 60fps content look like it's 120hz?

    Hi. TV manufacturers package Motion Interpolation or Motion Smoothness under different names and on LG TVs and on this LG 42-inch Class LG OLED evo C4 4K Smart TV 2024, Model # OLED42C4PUA, TruMotion is the name LG uses for its motion interpolation algorithm, which minimizes native image judder or stuttering and enables smoother motion representation in fast scenes. It can be found in the settings menu for the TV under Picture > Advanced Settings > Clarity > TruMotion, and under TruMotion, you will also find settings for: Off : Turns off the TruMotion. Cinematic Movement : Adjusts the shaking of the motion on the screen to make it feel like you are in a movie theater. Natural : Sets images with a lot of motions to look natural and clear. Smooth Movement : Softens fast-moving pictures. User Selection : Sets TruMotion manually. De-Judder : Adjusts juddering on the screen. De-Blur : Reduces the blurring effects of motion. OLED Motion / Motion Pro : You can make your video clearer by eliminating afterimages...^Ivan.
