LG OLED evo AI C5 4K Smart TV: Overview and First Impressions

The LG OLED evo AI C5 made a strong first impression the moment we unboxed it. The TV is slim, sleek, and clearly well built. LG has refined the design compared to earlier C series models. The bezels are thin and the stand is minimal, giving the screen a floating look in the room.

Setting up the TV took less than ten minutes. The webOS interface walked us through Wi Fi connection, streaming app downloads, and picture calibration. LG’s AI Sound and AI Picture settings kicked in right away. The TV analyzed our room’s lighting and adjusted the picture mode to match.

The picture quality stood out immediately. We loaded a 4K Dolby Vision demo clip, and the deep blacks, vivid colors, and smooth motion were all impressive. OLED technology gives each pixel its own light source. This means true black levels that LCD and Mini LED TVs cannot match.

The remote control is the familiar LG Magic Remote. It has a pointer function, built in microphone for voice commands, and quick access buttons for popular streaming apps. Alexa is built in, and the TV also works with Google Assistant and Apple HomeKit.

Overall, first impressions were very positive. The LG C5 looks and feels like a premium product. It sits in the sweet spot between LG’s entry level B series and the high end G5 gallery series.

Picture Quality: How Good Does the LG C5 Really Look?

Picture quality is the biggest reason to buy this TV. The LG C5 uses a WOLED panel with LG’s Brightness Booster technology. This means it gets brighter than the previous C4 model. HDR highlights hit harder, and the overall image has more punch in both dark and bright scenes.

SDR content looks great too. The AI Super Upscaling feature takes 1080p and 720p content and sharpens it to near 4K quality. Streaming shows on Netflix and Disney+ looked clean and detailed, even when the source material was not native 4K.

Color accuracy is excellent. The C5 covers a wide color gamut, and out of the box calibration is very close to reference standards. You will not need to hire a professional calibrator to get a good looking picture. However, if you want to fine tune things, LG’s picture settings menu gives you full control over white balance, gamma, color management, and more.

The Filmmaker Mode disables all processing and shows content exactly as the director intended. This is a great option for serious movie fans who want the most accurate presentation. Motion handling is smooth thanks to OLED’s fast pixel response time. There is no ghosting or blur during fast paced scenes.

Viewing angles are wide, which is a natural strength of OLED. Colors stay consistent even when you sit off to the side. This makes the C5 a good choice for larger rooms where not everyone sits directly in front of the screen.

Alpha 9 AI Processor Gen8: The Brain Behind the Beauty

The Alpha 9 AI Processor Gen8 is the engine that powers the LG C5. This chip handles everything from upscaling to sound optimization. It uses a neural network with multiple AI models to process each frame of content in real time.

AI Picture Pro is the standout feature. It analyzes each scene and adjusts brightness, contrast, sharpness, and color. The result is a picture that always looks its best, whether you are watching a dark thriller or a bright nature documentary. The chip also recognizes faces and enhances skin tones for a more natural look.

AI Super Upscaling is another key feature. It takes low resolution content and fills in missing detail using machine learning. The difference is visible. Old 720p shows look noticeably cleaner on the C5 compared to TVs without AI upscaling. It does not turn SD content into true 4K, but the improvement is real and consistent.

The processor also handles AI Sound Pro. This feature analyzes the audio signal and upmixes it to virtual surround sound. It identifies dialogue, music, and effects, then adjusts each element for a more immersive listening experience. The improvement is subtle but welcome, especially if you do not use an external soundbar.

LG claims the Gen8 chip is faster and more efficient than the Gen7 found in the C4. In practice, the webOS interface feels snappy. Apps load quickly, and switching between inputs is smooth. There is no noticeable lag or stutter during everyday use.

Top 3 Alternatives for LG OLED evo AI C5 4K Smart TV

If you want to compare the LG C5 with other top OLED TVs on the market, here are three strong alternatives worth considering.

1. Samsung S90F OLED 4K Smart TV (65 inch)

The Samsung S90F uses a QD OLED panel that delivers excellent color volume and brightness. It is a direct competitor to the LG C5 and edges ahead in peak brightness. It supports 144Hz VRR, Dolby Atmos, and Samsung’s AI Gen 3 processor. However, it does not support Dolby Vision, which may matter to some viewers.

2. Sony Bravia 8 OLED 4K Smart TV (65 inch)

The Sony Bravia 8 is known for its exceptional image processing and natural color reproduction. It uses the XR Processor and supports Dolby Vision and Dolby Atmos. It also has exclusive PlayStation 5 features like Auto HDR Tone Mapping. Sound quality through its Acoustic Surface Audio+ system is better than most built in TV speakers.

3. LG G5 OLED evo AI 4K Smart TV (65 inch)

The LG G5 is the step up from the C5 in LG’s lineup. It uses an MLA (Micro Lens Array) OLED panel that pushes peak brightness even higher. It also comes with a wall mount included and has a slimmer One Wall Design profile. If your budget allows, the G5 offers the brightest WOLED picture on the market.

Gaming Performance: A Dream for Console and PC Gamers

The LG C5 is one of the best gaming TVs you can buy. It supports 4K at up to 144Hz through its four HDMI 2.1 ports. Each port offers full 48Gbps bandwidth. This means you can connect a PS5, Xbox Series X, and a gaming PC all at the same time without any compromises.

Input lag is incredibly low. At 120Hz, input lag measures around 1.1 milliseconds. At 60Hz, it drops to about 4.5 milliseconds. These numbers are among the best in any TV tested. You will feel the difference in fast paced shooters and competitive online games.

The 0.1ms pixel response time means there is virtually no motion blur. Fast moving objects stay sharp and clear. This is a huge advantage of OLED over LCD technology. Ghosting is simply not an issue here.

G Sync compatibility and AMD FreeSync Premium keep the frame rate smooth and tear free. The TV supports HDMI Forum VRR as well. No matter what gaming hardware you use, the C5 adapts and delivers a fluid experience.

LG’s Game Optimizer menu gives you quick access to gaming specific settings. You can adjust black stabilizer, toggle low latency mode, and see real time stats like frame rate and HDR status. Dolby Vision Gaming is also supported, making compatible Xbox Series X titles look stunning with enhanced HDR.

Dolby Vision and HDR Performance

The LG C5 supports Dolby Vision, HDR10, and HLG. These are the three most common HDR formats for streaming, gaming, and broadcast content. The only notable omission is HDR10+, which Samsung uses. For most users, this will not be an issue since Netflix, Disney+, and Apple TV+ all use Dolby Vision.

Dolby Vision content looks fantastic on this TV. The C5 handles tone mapping well. Bright highlights in HDR scenes have plenty of detail, and dark areas remain deep and shadow free. The Brightness Booster technology helps the C5 push HDR peak brightness higher than the C4. Specular highlights on water, fire, and metal surfaces look vivid and lifelike.

The TV also excels at HDR gaming. Dolby Vision Gaming works with supported Xbox Series X titles. This adds dynamic HDR metadata to games, resulting in more accurate brightness and color on a frame by frame basis. The improvement is subtle but noticeable in games with varied lighting conditions.

Bright Room Ready is a feature LG highlights for the C5. It means the TV can maintain good HDR performance even in rooms with ambient light. The OLED panel gets bright enough to fight glare, although it still performs best in dimmer environments. The anti reflective coating on the screen helps reduce distracting reflections.

For movie fans, the combination of Dolby Vision and the perfect black levels of OLED creates a home cinema experience that rivals much more expensive setups.

Sound Quality and Audio Features

The LG C5 has a built in 2.2 channel speaker system rated at 40 watts. This is decent for a flat panel TV. Dialogue sounds clear, and there is enough bass to make action scenes feel impactful. It will not replace a dedicated soundbar or surround sound system, but it handles casual viewing well.

AI Sound Pro is the key audio feature. The processor analyzes the audio in real time and upmixes it to a virtual 9.1.2 surround sound experience. The effect is surprisingly convincing for built in speakers. You get a sense of width and height that makes content feel more immersive.

Dolby Atmos is supported natively. When you stream Atmos content from apps like Netflix, Apple TV+, or Disney+, the TV processes the spatial audio and creates an overhead sound effect. It is not the same as having ceiling speakers, but it adds a noticeable layer of depth.

The Wow Orchestra feature is worth mentioning. If you pair the C5 with a compatible LG soundbar, the TV speakers and soundbar work together. They combine their output for a wider, fuller sound stage. This is a clever way to upgrade your audio without replacing the TV speakers entirely.

Bluetooth audio output is also available. You can connect wireless headphones for private listening. There is a slight audio delay with Bluetooth, but LG’s Lip Sync adjustment helps compensate.

Smart TV Platform: webOS and Streaming Apps

The LG C5 runs webOS 25, LG’s latest smart TV operating system. The interface is clean, fast, and easy to use. The home screen shows a row of your favorite apps and recently watched content. You can customize the layout and pin your most used apps for quick access.

App support is excellent. All major streaming services are available, including Netflix, Disney+, Apple TV+, Amazon Prime Video, YouTube, Hulu, Peacock, and Paramount+. The apps load quickly and support their highest quality streams, including 4K Dolby Vision and Dolby Atmos where available.

LG Channels offers free ad supported streaming content. It works like a traditional TV channel guide but streams over the internet. The selection is decent and includes news, sports, movies, and lifestyle programming.

Voice control works through Alexa built in, Google Assistant, and Apple AirPlay 2. You can ask the TV to change channels, search for content, adjust settings, or control smart home devices. The built in microphone on the Magic Remote picks up commands accurately.

Chromecast is built in too. This means you can cast content from your phone or tablet directly to the TV. Apple users can use AirPlay 2 to stream from iPhones, iPads, or Macs.

The webOS app store also includes a selection of games, fitness apps, and music streaming services. The platform receives regular updates from LG, which add new features and improve performance over time.

Design and Build Quality

The LG C5 has a modern, minimalist design that fits well in any room. The bezels around the screen are extremely thin. From the front, it looks like a floating display. The panel itself is thin at the top, though it gets thicker at the bottom where the electronics and speakers are housed.

The stand is a simple pedestal style base. It supports the TV securely and does not wobble. Cable management is handled through a small channel in the back of the stand. If you prefer wall mounting, the TV uses a standard 300x300mm VESA pattern. The 65 inch model weighs about 40.8 pounds with the stand.

Build quality feels solid. The back panel is made of metal and plastic. The materials do not feel cheap. LG has improved the build compared to earlier C series models, and the C5 now feels closer to the premium G5 in terms of construction quality.

The Magic Remote is lightweight and ergonomic. It sits comfortably in your hand. The scroll wheel and point and click interface make browsing menus and apps fast and intuitive. The remote uses Bluetooth, so you do not need to point it directly at the TV.

Available in 42, 48, 55, 65, and 77 inch sizes, the C5 has an option for almost every room size. The 42 inch model doubles as a fantastic PC monitor, while the 77 inch version fills a large living room with an immersive viewing experience.

Connectivity and Ports

The LG C5 offers a generous selection of ports. It has four HDMI 2.1 ports, each supporting 48Gbps bandwidth. This means all four ports can handle 4K at 120Hz with VRR, eARC, and ALLM. You do not need to worry about which port to use for your gaming console.

There are also three USB ports for connecting external storage devices or media players. An optical audio output is available for connecting to older soundbars or receivers. The TV has an Ethernet port for a wired internet connection, which offers more stable performance than Wi Fi.

Wi Fi 6 is built in for wireless connectivity. Bluetooth 5.1 is also included for connecting wireless headphones, keyboards, or game controllers. The wireless performance is fast and reliable for streaming 4K content.

One HDMI port supports eARC (Enhanced Audio Return Channel). This allows you to send high quality audio formats like Dolby Atmos and DTS:X to a compatible soundbar or AV receiver through a single HDMI cable.

The C5 also supports HDMI CEC, which lets you control connected devices with the TV remote. For example, you can turn on your soundbar and adjust its volume without switching remotes. This small convenience adds up in daily use.

LG C5 vs LG C4: What Has Changed?

If you own the 2024 LG C4, you might wonder whether upgrading to the C5 is worth it. Here are the key differences between the two models.

Brightness is the biggest upgrade. The LG C5 uses an improved OLED evo panel with a more effective Brightness Booster. It reaches higher peak brightness in both SDR and HDR content. The difference is most noticeable in bright rooms and during HDR highlights. RTINGS confirmed the C5 is the brightest C series OLED ever made.

The processor has been updated. The C5 uses the Alpha 9 Gen8 chip, replacing the Gen7 in the C4. The new chip offers better AI upscaling, improved noise reduction, and faster processing. The webOS interface feels slightly snappier as a result.

Design has been refined. The C5 has a slightly updated stand design and thinner bezels. The changes are subtle but give it a more modern look. The build quality also feels a step above the C4.

Gaming features remain similar. Both TVs support 4K at 144Hz, VRR, G Sync, and FreeSync Premium. The C5 has a slight edge in input lag measurements, but the difference is small enough that most gamers will not notice.

If you have a C4, the upgrade is not essential. The improvements are meaningful but incremental. However, if you are coming from a C3 or older model, the jump to the C5 will feel significant. The brightness boost alone makes a noticeable difference in everyday viewing.

Who Should Buy the LG OLED evo AI C5?

The LG C5 is a great fit for a wide range of buyers. Movie fans will love the Dolby Vision support, deep OLED blacks, and accurate color reproduction. It delivers a true home cinema experience, especially in a dim room.

Gamers will appreciate the low input lag, 4K 144Hz support, and full HDMI 2.1 features across all ports. Whether you play on a PS5, Xbox Series X, or a high end gaming PC, the C5 handles it all with ease. The Dolby Vision Gaming support is a bonus for Xbox users.

Casual viewers who stream a lot of content will enjoy the webOS platform, fast app loading, and excellent AI upscaling. Even older content looks good thanks to the Gen8 processor. The built in speakers are adequate for everyday viewing without a soundbar.

The C5 is also a solid choice for bright rooms. Its increased brightness and anti reflective coating help it perform better in ambient light than previous C series models. While OLED still looks best in dark rooms, the C5 holds its own in brighter conditions.

If you want the absolute best OLED picture quality and do not mind spending more, consider the LG G5 or Samsung S95F. But for the price, the LG C5 offers the best combination of picture quality, gaming performance, and smart features in its class.

Potential Drawbacks to Consider

No TV is perfect, and the LG C5 has a few limitations. Burn in remains a concern for OLED panels. If you display the same static image for extended periods, you risk leaving a permanent mark on the screen. LG includes burn in prevention features like pixel shifting, screen savers, and logo dimming. With normal use, burn in should not be an issue for years.

The TV does not support HDR10+. This is Samsung’s competing HDR format. Most major streaming services use Dolby Vision, so this omission affects only a small number of users. Still, it is worth noting if you rely heavily on HDR10+ content from Amazon Prime Video.

There is no ATSC 3.0 tuner. This means the C5 does not support over the air 4K broadcasts through NextGen TV. If you watch a lot of antenna based content, this could be a deal breaker. LG reserved the ATSC 3.0 tuner for its higher end models.

Built in sound, while improved, is still limited. The 40 watt speaker system is fine for casual viewing. But if you watch a lot of movies or play games with intense audio, you will want to add a soundbar or AV receiver. The Wow Orchestra feature helps, but it requires an additional LG soundbar purchase.

The price is still high for budget conscious buyers. While the C5 is cheaper than the G5, it remains a premium product. If you are looking for a large screen TV under $1,000, you may need to explore Mini LED options instead.
