Specs and performance comparison
Sound Quality
The LG C4 is decked out with a suite of audio enhancements including Dolby Audio, Dolby Atmos, and DTS:X, ensuring that every auditory detail is delivered with clarity and depth. Its AI Sound Pro feature further enhances this experience by tailoring the audio output to match the content, ensuring that whether you’re watching a fast-paced action movie or a dialogue-heavy drama, the sound is always optimized for the best listening experience.
In contrast, Sony’s A90J introduces a novel audio concept with its Acoustic Surface Audio+ technology, where the TV screen itself doubles as the speaker. This innovative approach offers a uniquely immersive audio experience, with sounds emanating directly from their corresponding actions on the screen, adding an extra layer of realism to your viewing.
Combined with Dolby Atmos and other high-quality sound technologies, the A90J not only matches the C4 in terms of clarity and depth but also surpasses it with its ability to deliver a more robust bass response, making it a strong contender for those prioritizing sound in their TV selection.
As previously mentioned, the main difference between the two TVs is connectivity, which can play a vital role when considering a consumer’s intended use. Gamers who hope to connect multiple devices or consoles during gameplay would find the LG C4 with its 4x HDMI ports the more useful option. Conversely, the Sony A90J with only 2x HDMI ports definitely lacks the versatility of its competitor.
Performance and brightness
At the heart of Sony’s A90J lies the Cognitive Processor XR, outshining the LG C4’s Alpha a9 AI processor with its superior image processing capabilities, designed to deliver a more natural and accurate viewing experience. This processor is finely tuned to complement the TV’s OLED panel, enhancing the overall picture quality.
Where the Sony A90J further distinguishes itself is with its XR Motion Clarity technology, adept at minimizing motion blur. This technology, which manipulates the OLED panel’s backlight, ensures smoother and more defined visuals during rapid scene changes, a feature particularly beneficial for fans of action-packed movies and sports.
Coupled with its exceptional brightness, the A90J stands out as a formidable choice for brightly lit environments, offering vivid and dynamic imagery where other OLED TVs might falter.
On the other hand, the LG C4 doesn’t lag far behind, boasting the Alpha a9 AI processor that actively works to polish the image quality by reducing noise, improving brightness levels, sharpening vibrant colors, and amplifying deep blacks. It also incorporates AI-driven enhancements, pushing the boundaries of what’s possible with picture quality.
Price comparison
The LG C4 OLED and Sony A90J find themselves closely matched in terms of pricing, each presenting compelling choices within the same ballpark. For the 55-inch models, both TVs are tagged at $1,999, making them equally attractive from a financial standpoint. The differentiation comes into play with the 65-inch models, where the Sony A90J asks for a slight premium at $2,999, just $200 more than the LG C4’s $2,699.
| Sizes | LG C4 OLED | Sony A95L |
|---|---|---|
| 55 inches | $1,999 | $1,999 |
| 65 inches | $2,699 | $2,999 |
This marginal price increase for the Sony model might be justifiable for users prioritizing superior image processing and sound quality offered by its Cognitive Processor XR and Acoustic Surface Audio+.
LG C4 OLED vs Sony A90J – which is better?
When it comes to choosing between the LG C4 OLED and the Sony A90J, the decision is nuanced. The Sony A90J edges out with superior brightness and overall quality, making it an attractive option for those prioritizing visual excellence. However, the LG C4’s advancements in AI technology and its greater connectivity options present a compelling case for users with specific needs, such as gaming or a home theater setup requiring multiple inputs. Ultimately, while the A90J may hold the title of the better TV in a general sense, the C4’s unique features ensure it remains a highly competitive and suitable choice for certain audiences.
When is the LG C4 coming out?
There has been no official confirmation from LG as to when the LG C4 will be released.
