Sony A80K OLED 4K Smart TV Overview

The Sony A80K is a 2022 OLED TV from Sony’s BRAVIA XR lineup. It features the Cognitive Processor XR, which Sony says mimics how humans see and hear. This processor analyzes content in real time and applies intelligent adjustments to color, contrast, and clarity.

The A80K uses a WOLED panel with XR OLED Contrast Pro technology. A heat sink behind the panel allows it to push brightness higher than some older OLED models. The TV supports Dolby Vision, HDR10, HLG, and IMAX Enhanced content.

Sony designed the A80K with film enthusiasts in mind. The Netflix Adaptive Calibrated Mode and BRAVIA CORE streaming service cater to people who want studio accurate picture quality. The TV also supports PlayStation 5 specific features like Auto HDR Tone Mapping.

Pros:

• Outstanding color accuracy and natural image processing
• Acoustic Surface Audio+ creates immersive sound from the screen

• Heavier and bulkier design compared to LG
• Discontinued model with limited new stock availability

Picture Quality Comparison

Picture quality is the main reason people buy OLED TVs. Both the LG C3 and Sony A80K deliver perfect blacks and infinite contrast because each pixel produces its own light and turns off completely for black scenes.

The LG C3 pushes higher peak brightness numbers. Tests show it reaches around 800 to 900 nits on a 10% HDR window. The Sony A80K peaks around 700 to 800 nits in similar tests. This gap matters most during bright HDR highlights like sunlight reflections and explosions.

The Sony A80K wins on color accuracy straight out of the box. Sony’s Cognitive Processor XR applies a more natural and film like look. Skin tones appear more realistic. The LG C3 leans slightly more vivid and saturated, which many viewers actually prefer for casual watching.

Both TVs handle shadow detail and near black performance well. You will see subtle details in dark scenes on either model. The difference in daily use is small, and both rank among the best TVs for dark room viewing.

Gaming Performance

The LG C3 is the clear winner for gaming. It offers four HDMI 2.1 ports, each supporting 4K at 120Hz. This means you can connect a PS5, Xbox Series X, and a gaming PC at full bandwidth without swapping cables.

The C3 supports NVIDIA G Sync, AMD FreeSync Premium, and VRR (Variable Refresh Rate). These features eliminate screen tearing and stuttering during gameplay. The Game Optimizer menu lets you adjust settings quickly and monitor real time frame rates.

Input lag on the LG C3 measures around 9 ms at 4K 120Hz in Game Mode. This is excellent and nearly imperceptible during fast paced games.

The Sony A80K has only two HDMI 2.1 ports. It supports VRR but lacks native FreeSync. Input lag sits around 17 ms at 4K 120Hz, which is still good but not as fast as the LG. Sony does offer Auto HDR Tone Mapping for PS5, which is a nice bonus for PlayStation owners.

Sound Quality

Sound quality is one area where the Sony A80K pulls ahead of the LG C3. Sony uses Acoustic Surface Audio+ technology. This system places actuators behind the OLED panel that vibrate the screen itself to produce sound.

The result is that dialogue and sound effects seem to come directly from the on screen action. This creates a more natural and immersive listening experience. The A80K also includes two subwoofers at the back for added bass depth. Total audio output is rated at 50 watts.

The LG C3 uses a conventional down firing speaker system rated at 40 watts with a 2.2 channel setup. It supports Dolby Atmos and produces decent sound for a flat panel TV. But it lacks the spatial accuracy and richness that the Sony provides.

Both TVs benefit from connecting to a soundbar or home theater system. However, if you want to skip an external audio setup, the Sony A80K offers a noticeably better experience right out of the box.

Smart TV Platform and Interface

The LG C3 runs webOS 23, which is a refined and fast smart TV platform. The home screen displays your favorite apps, recent inputs, and content recommendations. It supports Alexa built in, Google Assistant (via voice), and Apple AirPlay 2. The LG ThinQ app lets you control the TV from your phone.

The included Magic Remote has a pointer function that works like a mouse cursor on screen. Many users find this faster than traditional D pad navigation. App availability is strong, with all major streaming services like Netflix, Disney+, YouTube, Apple TV+, and Amazon Prime Video.

The Sony A80K runs Google TV, which organizes content around personalized recommendations. It supports Google Assistant with voice search built into the remote. You also get Chromecast built in, so you can cast content from your phone or laptop with a tap.

Google TV’s app library is massive, drawing from the Google Play Store. The interface can feel busy with recommendations, but you can customize it. Apple AirPlay 2 and HomeKit are also supported on the Sony.

HDR Format Support

Both TVs support a wide range of HDR formats. The LG C3 supports Dolby Vision, Dolby Vision IQ, HDR10, HLG, and Filmmaker Mode. Dolby Vision IQ uses the TV’s built in ambient light sensor to adjust HDR brightness based on your room lighting.

The Sony A80K supports Dolby Vision, HDR10, HLG, and IMAX Enhanced. The IMAX Enhanced support is a Sony exclusive advantage. It allows optimized playback of IMAX certified content on streaming platforms.

Neither TV supports HDR10+, which is Samsung’s competing dynamic HDR format. This omission matters only if you watch a lot of content encoded in HDR10+ from services like Amazon Prime Video that offer it.

For most users, Dolby Vision is the dominant format, and both TVs handle it beautifully. The LG C3 displays slightly brighter Dolby Vision highlights, while the Sony A80K renders Dolby Vision colors with a more restrained and natural palette.

Design and Build Quality

The LG C3 features a sleek and minimalist design. The panel is extremely thin at the top, roughly 4 to 5 mm, with a slight bulge at the bottom for the electronics. The bezels are narrow and modern. The flat pedestal stand is sturdy and unobtrusive.

Wall mounting the LG C3 is straightforward. The slim profile sits close to the wall and creates a clean look. The TV weighs around 16.8 kg (37 lbs) for the 65 inch model without the stand.

The Sony A80K has a slightly thicker and heavier build. It weighs approximately 19.1 kg (42 lbs) for the 65 inch version without the stand. The stand offers two positions: a standard centered position and a narrower tabletop position for smaller furniture.

Sony’s build quality feels premium and solid. The materials have a refined finish. However, the LG C3 wins on slimness and weight, making it easier to mount and move.

Connectivity and Ports

Port selection matters for anyone with multiple devices. The LG C3 provides four HDMI 2.1 ports, one USB 2.0 port, an Ethernet port, an optical audio output, and a tuner input. All four HDMI ports support full 48 Gbps bandwidth for 4K 120Hz content.

The Sony A80K has four HDMI ports total, but only two are HDMI 2.1. The other two are HDMI 2.0. This limits you if you have more than two devices that need 4K 120Hz. It also includes two USB ports, an Ethernet port, an optical audio output, and a tuner input.

Both TVs support Wi Fi (802.11ac) and Bluetooth 5.0 for wireless connections. The LG C3 also supports Bluetooth Surround Ready, which lets you pair LG wireless speakers for a surround sound setup without extra cables.

The LG C3’s four full HDMI 2.1 ports give it a significant advantage for users with a gaming console, Blu ray player, and streaming device all connected at once.

Upscaling and Motion Handling

Both TVs do an impressive job upscaling lower resolution content to fill their 4K panels. The Sony A80K is widely praised for its XR 4K Upscaling technology. It adds detail and texture to 1080p and 720p sources, making them look remarkably close to native 4K. Sony’s processing retains natural textures and avoids the oversharpened look some competitors produce.

The LG C3 uses AI Super Upscaling 4K powered by the a9 Gen6 processor. It does a very good job sharpening lower resolution content. Edges are clean, and noise is well controlled. However, side by side, the Sony produces a slightly more refined result with fine details.

For motion handling, both TVs support a 120Hz native refresh rate. The Sony A80K uses XR Motion Clarity to reduce blur and judder. The LG C3 uses OLED Motion Pro with optional black frame insertion. Both deliver smooth and clear motion for sports and action content.

Value for Money

Price is a key factor in this comparison. The LG C3 65 inch launched at around $1,799 and has dropped significantly over time. You can often find it well under that price now. The LG C3 is widely available from most major retailers.

The Sony A80K 65 inch launched at $2,499 and has also seen big price cuts. As a 2022 model, it can sometimes be found at clearance prices that bring it close to or below the C3’s current street price. Stock is more limited since it is a discontinued model.

Considering the feature set, the LG C3 offers more for your money. It has newer processing, better gaming capabilities, and broader availability. The Sony A80K is the better pick if you find it at a steep discount and care most about cinematic picture quality and sound.

Both TVs represent excellent value in the premium OLED segment. You cannot go wrong with either choice at their current prices.

Which TV Should You Buy?

Your ideal pick depends on how you plan to use the TV. If you are a gamer who owns a PS5, Xbox Series X, or a gaming PC, the LG C3 is the smarter purchase. Four HDMI 2.1 ports, lower input lag, and VRR support across G Sync and FreeSync make it the best gaming OLED in this comparison.

If you are a movie and TV enthusiast who values accurate color, natural motion, and better built in sound, the Sony A80K deserves your attention. Sony’s image processing has a cinematic quality that film lovers appreciate.

For a bright living room, the LG C3’s higher peak brightness gives it a slight advantage with HDR content. For a dark home theater, both TVs perform beautifully, but the Sony’s more accurate processing may give it a subtle edge.

If you want the most future proof option, the LG C3 is the better bet. It is a year newer, runs a more recent processor, and has a broader set of modern gaming and smart features.

Final Verdict

The LG C3 OLED Evo and the Sony A80K OLED are both exceptional televisions. They share the same WOLED panel foundation and deliver the deep blacks, wide viewing angles, and rich colors that make OLED technology special.

The LG C3 wins overall for its superior brightness, complete gaming feature set, four HDMI 2.1 ports, and newer smart platform. It suits a wider range of users, from casual viewers to dedicated gamers.
