Sony A90J Vs LG G1 – Features Face to Face

Panel Technology

OLED panel technology is excellent for color accuracy, contrast, and other essential features that can increase user experience. OLED TVs have extremely thin screens due to very advanced technology. 

Both of these TVs use OLED technology. The technology allows individual pixels to emit their own light. So, these panels have perfect blacks and fantastic motion handling. The downside to these panels is low brightness. 

The LG G1 has an OLED Evo screen. The panel has enhanced brightness levels and has no increased risk of burn-in. It is an incredible technology that gives the LG G1 TV an advantage in this segment.

Winner: LG G1

Image Processor

More people every day are opting for smart TVs which follow the latest technological innovations. However, you can use your favorite applications such as Facebook, Netflix, or Youtube by using a smart TV. Most importantly, a built-in processor makes the TV image clearer and optimized. 

The LG G1 uses the α9 Gen 4 AI Processor. This processor upscales the image to 4K from HD or even lower resolutions. So, whether you want to watch 720p or 480p content, this TV can deliver a perfectly optimized picture! The disadvantage is the face handling because it can have a reddish hue. 

The Cognitive Processor XR, a part of the Sony A90J, divides the screen into hundreds of zones. The processor identifies every individual object in the zones and allows them to communicate with each other. This is called cross-analyzation.

As you can see in the picture above, color and clarity are significantly improved. Therefore, this processor makes the Sony A90J ideal for watching movies.  

Winner: Sony A90J

Motion Technology

Refresh rate is one of the most important features you should pay attention to. This number shows you how many images your TV can show per second. More images per second mean better motion handling. When the refresh rate is low, you can expect blurring and ghosting. 

The LG G1 has a 120 Hz native refresh rate and supports variable refresh rates. The Sony A90J also has a native refresh rate of 120 Hz. However, the Sony A90J doesn’t support a variable refresh rate

So, the LG model is a better choice for you if you want to play video games, especially if we consider that this model also has FreeSync, which Sony doesn’t. 

Winner: LG G1

Picture Quality

The number of pixels displayed on the screen is another feature you need to consider when choosing a TV. Some basic TV models have full HD resolution, which is enough to watch TV shows and movies. 

But, if you are a true fan of watching movies and playing video games, the best resolution is 4K. As we said earlier, another important factor that, together with the resolution, determines the image quality is the refresh rate. 

Both of these models have a 120 Hz refresh rate and 4K resolution. However, the most significant difference between these two is that the LG G1 model can achieve 1440p resolution at 120 Hz, while the Sony model can’t.   

ResolutionLG G1Sony A90J
4K/120HzYes (native support)Yes (native support)
1440p/60HzYes (forced resolution)Yes (forced resolution)
1080p/120HzYes (native support)Yes (native support)

Contrast Ratio/Black Level

Since both of these TVs use OLED technology, they produce perfect blacks. The perfect deep blacks are achieved thanks to an infinite contrast ratio. So, if you plan to watch a lot of movies, each of these two TVs can be a good choice. 

Winner: Draw

Local Dimming

The OLED screens don’t have any backlighting. It means they also don’t have local dimming features. Instead, their individual pixels emit their own light so they can turn on and off individually. It results in perfect blacks and no blooming around objects. 

Winner: Draw

Peak Brightness

Even though the LG G1 model has an OLED Evo panel with enhanced brightness, these TVs are similar. The LG G1 has a maximum brightness of 850 Nits. The Sony A90J has a maximum brightness of 890 Nits, which is slightly better. But overall, in terms of peak brightness, these TVs offer similar performance. 

Winner: Sony A90J  


OLED TVs have vivid colors and perfect blacks. They are great at displaying dark colors, and sometimes they have a slight problem with displaying brighter colors. 

Both of these TVs have a good color volume. But, the Sony A90J is slightly better when it comes to color gamut and gradient handling, even though it has some banding in green and grey. The LG model has some trouble with banding in darker shades. 

Winner: Sony A90J

Viewing Angle

In general, OLED TVs have fantastic viewing angles. These two models are not an exception. So, if you want to view your TV at wide angles, you will not experience any color washout or brightness loss. 

Even though the best angle to watch a TV is straight in front of it, these two OLED TVs people can watch from any angle. 

Winner: Draw

Reflections / Anti-glare

OLED Evo panels handle reflections very well. Since the LG G1 has this type of panel, the reflection handling should not be an issue. Although, you might experience a little bit of purple tint. The Sony A90J has excellent reflection handling, even though it has an OLED screen. 

Winner: Sony A90J

Sound Quality

The LG G1 has 60 Watts speakers and 4.2 channels. The Sony model has 60 Watts (20W + 20W + 10W + 10W) speakers, as well. But it has 2.2 channels. Both of these support Dolby Atmos and Dolby Digital and neither have an integrated soundbar. 

What both of these models have in common when it comes to sound quality is the lack of bass. The Sony model has weak bass, whereas the LG model hardly has any bass. If you opt for the LG G1, investing in an LG soundbar and pairing it with a subwoofer is recommended. 

Since the LG G1 has more audio channels, it has a slight advantage in this segment. But keep in mind that both models don’t have good bass. Therefore, check out our list of the best soundbars under 300.

Winner: LG G1

Smart TV Platform (Operating System)

The LG G1 TV uses the WebOS 6.0 operating system. You can expect a smooth, easy-to-use interface with a beautiful design. It supports all of the most popular streaming services like Netflix, HBO Max, Hulu, Amazon Prime, YouTube, and more.

But, since the LG G1 comes integrated with both Google Assistant and Amazon Alexa, it is better in this segment. 

Winner: LG G1

Wireless technologies

The LG G1 and Sony A90J models support the Wi-Fi-connection, 2.4 GHz and 5 GHz. In addition, both TVs support Bluetooth, as well. But, the LG G1 supports Bluetooth 5.0, whereas the Sony A90J supports the 4.2 version of Bluetooth. 

Winner: LG G1

Standout features

The LG G1 TV model stands out in the market for one thing – stunningly beautiful design. This model has no backlighting, so the screen is very thin. Thin gallery design allows the LG G1 to sit flush against the wall, just like a painting

It is made mostly from metal and has a cable management system. For the people who prefer beautiful design and those who want to keep the TV on the wall, the LG G1 might be a perfect choice. 

However, the LG G1 doesn’t come with a stand. Therefore, if you want to put the TV on the stand, you will need to purchase the Gallery Stand.
