5 facts to compare: LG vs Vizio TV

LG and Vizio use different types of technologies, panel types and shows different Smart TV performance. This section will focus on the 5 major dissimilarities between LG vs Vizio.


How well a TV manufacturer thinks about its internal technologies will affect the picture quality. The number of local dimming zones, local dimming type, or panel type will change the final image displayed on the screen.

Panel technology

Different TV manufacturers focus on different panel technology. This will affect how the display allows the picture to look.


LED/LCD display is the most common technology used by all TV manufacturers. The LCD display uses LED as a backlight. The backlight can be of different types:

  • Edge-lit
  • Direct-lit
  • local dimming
  • Full-Array Local Dimming (FALD)

Among the techniques above, FALD delivers excellent image quality where the TV can control the number of zones. Vizio has some decent models in 2016, 2017 and is making these LCD/LED TVs till now. For the 2016-2017 Vizio M series, they use 64 zones in the full array backlight.

You will find this in models like the M65-D0, M55-D0, M60-D1, M70-D3, M50-D1, M80-D3. Vizio D series also use this technology and will be available in the following models: Vizio D70-D3, Vizio D65U-D2, Vizio D55U-D1, Vizio D50U-D1, Vizio D39H-DO, Vizio D32-D1

In Vizio V series 2019, some models like the V505-G9 or V605-G3 don’t have any local dimming zones while others like V656-G4 have 12 local dimming zones.  In LG, there are several models like the LG 22LJ4540 IPS LED TV.


IPS panels are famous because of their wide viewing angle. Since TV is a medium of entertainment people often want to watch with friends and family so a broad view angle is important. IPS rearranges the molecules of the liquid crystal layer.

IPS panels are well-known for having excellent color contrast and picture quality compared to VA or TN panels. While they have outstanding color contrast but they have slower response times and are very expensive. Vizio E75-F2 or the LG 55UK6700PVD UK6700 series are some of the IPS models.


OLED TVs don’t need backlight technology. They have perfect blacks and accurate color reproduction. In OLED each pixel is independent and produces its own light. The picture quality and design are better compared to LED panels. The color contrast is infinite and the view angle is broad. They also have a faster response time that reduces blur.

Comparing LG vs Vizio TV, Vizio just released their first OLED TV last year in 2020. And the displays are made by LG which is the only company to manufacture them. Some examples of TV models with OLED are the  Vizio OLED55-H1, LG GX 65” OLED65GXPUA, and LG G1 OLED65G1PUA TV.

Nano cell

Between LG vs Vizio TV, the LG uses Nano cell technology. With the help of particles, it can improve the color production of red and green shades. They ensure color accuracy when viewed directly or from an angle. The LG Nano cell UHD TV delivers excellent image quality with Dolby Vizio, HDR 10, and HLG.

These TVs also use Dolby Atmos to give you room-filling audio. you can choose the LG Nano cell 86NANO90UNA 90 Series.


Vizio released its QLED TVs in 2018. Comparing LG vs Vizio TV, the LG TVs have OLED TVs whereas the Vizio has QLED TVs along with OLEDs. Between LG vs Samsung, all OLEDs are manufactured by LG whereas, all QLEDs are manufactured by Samsung. Vizio renames the QLED as Quantum color which deploys the Quantum Dot technology.

QLEDs brighten up and make colors look vivid. These Quantum Dots are responsible to release red and green shades. Vizio Quantum color technology is found in M-series, P-series, or P- that has a wide color gamut. Scoring 85% in rec2020, Vizio claims the QLED has the ‘widest colorspace in the industry

AI ThinQ

Comparing LG vs Vizio, both use Artificial Intelligence to improve TV features but LG emphasizes and advertises its LG ThinQ or LG Picture more. LG uses its own algorithms to help produce innovative consumer products. You will find AI ThinQ in 4k UHD TVs and OLEDs.

They use AI in refrigerators, smartphones, and speakers as well.TVs with Alpha 9 Gen 2 Intelligent Processor also uses AI.  By studying ‘content and ambient light’, the AI helps to improve the clarity, sharpness, and minute details of the objects.

With the help of AI Sound Tuning, it can detect your position and despite the room arrangement, you will hear the best sound. Last year Vizio mentions the use of AI to improve image quality. you will find the IQ Ultra processor in Vizio SmartCast models where it uses Artificial Intelligence and machine learning.

We recommend: OLED pane is the best overall compared to all others.

Image quality

Having a 4k TV isn’t enough because a 4k resolution is the standard now and is available on every TV set. To have impressive picture quality other things like color contrast, upscaling, HDR, and dynamic range matter. Between LG vs Vizio TV’s picture quality, we see that they use different techniques and panels to make their displays look better.

Vizio rules out other TVs in terms of performance at a cheaper price. Their TVs have excellent color and contrast, decent to a high level of brightness and the evenness of black and gray is good in most TVs. Overall, at this cheaper price, you will be more than happy with the Vizio TV picture quality.

For LG, they are a step ahead compared to Vizio. With various panel technologies and AI techniques, LG always wants to maintain quality. Models like LG CX OLED is one of the best TV with excellent picture quality. these TVs have superior contrast, deep and dark blacks, impressive uniformity, vivid color as well as broader view angle.

We recommend: LG is best for picture quality

Audio quality

LG vs Vizio TV, which one has better sound quality? Usually, TV speakers are moderately good for listening. We always recommend adding a soundbar if you want an immersive sound experience while watching movies or playing games. The LG sound quality can get decent loud and they have audio reliability.

This means the overall sound quality of LG is better. The speakers don’t get distorted and have less signal noise. The dialogs and voices are crystal clear which is similar for Vizio as well. For Vizio, the audio quality can get loud but it should improve in terms of clarity. Check out LG soundbars here.

For soundbars, you can choose the LG GX soundbar or Vizio M21D-H8 soundbar.

We recommend: LG

Build Quality

When we buy a TV we want it to use it for at least 10 years. That’s why the sturdiness of the TV material is important. Comparing LG vs Vizio TV build quality, the LG is comparatively stronger than Vizio. In some Vizio models like the Vizio V series 2019, the TV wobbles and becomes unsteady on its feet. Others like the P series Quantum X remains stable.

Most Vizio TVs are entirely made out of plastic whereas the LG includes metals along with plastic. Both brands have sleeker TVs with an excellent design but LG is quite sturdy in terms of TV material and TV feet. LG also suffers from less build quality issues.

We recommend: LG

Smart features

Between LG vs Vizio, the TV best Smart TV is the LG with its OLED and webOS. The main reason to buy LG with webOS is that the user interface is faster and smoother compared to the Smartcast in Vizio. This means you can easily move from one app to another and it will take a shorter time to open an app. LG takes only 2s to open YouTube whereas Vizio takes 10s.

LG also comes with thousands of apps and content. You can edit and rearrange contents and LG also has ThinQ AI, Google Assistant, and Alexa built-in. there is a new thing known as the Sports feature with which you can stay updated with the news of your favorite team. You can also watch content from Netflix and YouTube in 4k.

Although SmartCast is not very smooth to use, it is quite decent. Similar to webOS, it will support all the major apps and contents. What makes SmartCast special is the built-in Google Chromecast with which you can cast or mirror almost anything to your TV. The interface shows three rows showing suggested contents, shows, movies, and your apps.

We recommend: LG with webOS
