Connecting your Vizio soundbar to an LG TV is straightforward for most models using either an HDMI or optical cable. Optimizing the setup ensures you get immersive audio to match the brilliant LG picture quality.
This comprehensive guide provides beginner-friendly instructions for seamlessly integrating Vizio soundbars with LG smart TVs. Learn how to connect soundbars via HDMI ARC or optical cables, adjust audio settings for the best sound quality, and resolve common troubleshooting problems between LG televisions and Vizio sound systems.
Why Add a Vizio Soundbar to an LG TV?
LG manufactures innovative, cutting-edge 4K and 8K UHD televisions for stunning visuals. However, even high-end LG OLED and NanoCell TVs still rely on small built-in speakers which limit sound performance.
Adding a Vizio soundbar significantly enhances audio quality with dedicated woofers and tweeters for deeper bass, clearer dialogue, and a wider, more immersive soundstage.
Key benefits of connecting a Vizio soundbar to an LG television include:
- Enhanced clarity and detail – Hear every line of dialogue crisply without straining
- Thunderous bass – Feel the action from blockbuster soundtracks and effects
- Surround sound experience – Get drawn into movies and sports with 3D audio
- Compact, clutter-free setup – Avoid complicated receivers and speaker wires
- Easy installation – Connect in minutes with a single cable
- Universal compatibility – Works seamlessly with the latest webOS LG smart TVs
- Value pricing – Quality sound upgrade at budget-friendly prices
Vizio makes it simple to boost your LG television’s built-in sound through various soundbar models ranging from 2.0 channel designs with crystal clear audio to 5.1 channel systems with wireless surrounds for a complete home theater configuration.
Do LG TVs Work With Vizio Soundbars?
Absolutely – Vizio soundbars are completely compatible with LG smart televisions, making these a popular audio upgrade for enhancing both TV shows and movies.
The key is connecting the devices properly to transmit sound. Modern LG television models include dedicated ports just for pairing soundbars, streamlining the integration process.
You have two main options for hooking up a Vizio soundbar to an LG TV:
HDMI ARC – The HDMI Audio Return Channel allows digital audio to be sent over the same HDMI cable used for video. This method provides higher resolution sound and convenient control features.
Optical Audio – Optical cables, also called SPDIF or TOSLINK, offer an all-digital signal to transmit sound as well. This is the simplest connection option if HDMI ARC is not available.
As long as you choose the appropriate connection method for your specific models, setup is quick and seamless between LG and Vizio.
In some cases, you may need to adjust TV settings to route audio output to the soundbar correctly. But overall the process is straightforward even for beginners.

FAQs About Using Vizio Soundbars with LG TVs
Still have some questions about pairing Vizio sound systems with LG televisions? Here are answers to the most frequently asked questions:
What is the best way to connect a Vizio soundbar to an LG TV?
For full integration including 4K HDR passthrough and convenient volume/power control of both devices, use the HDMI ARC ports. This carries digital video and audio over a single cable. If HDMI ARC connections are not available, default to an optical/SPDIF audio cable for TV sound transmission to the soundbar.
Do you need HDMI for Vizio soundbar to work with LG?
No, Vizio soundbars will function when connected to an LG TV using either HDMI or optical cables. However for the latest models, HDMI ARC delivers higher resolution audio and metadata for the full Dolby Atmos/DTS:X decoding by the soundbar.
Should audio output be Bitstream or PCM from LG TV?
We suggest leaving Audio Format/Digital Sound Out on Auto first, which outputs Dolby and DTS bitstreams when supported by the content and connected audio device. Alternately trying PCM mode can resolve sync issues in some cases but is limited to basic stereo.
Why is there a delay between LG TV and Vizio soundbar?
A/V sync problems typically arise from outdated firmware or incompatible settings between components. Beyond factory resetting and updating to the latest firmware on both TV and soundbar, turning SIMPLINK On often minimizes lag by better coordinating devices over HDMI connections.
Do you need a subwoofer with a Vizio soundbar for an LG TV?
While premium Vizio soundbars include a built-in sub for powerful bass, many compact models can pair wirelessly with a separate external active subwoofer for added low frequency effects. This brings a fuller soundstage to movies and music. Place the wireless sub centrally below or beside the entertainment center.
Can any Vizio soundbar connect to an LG TV via Bluetooth?
Vizio produces various soundbar models ranging from older wired systems to the latest offerings with integrated Bluetooth. Bluetooth support enables conveneint wireless pairing with LG smart TVs. Just remember bluetooth connections can introduce slight A/V delay. Optical or HDMI wired configurations provide synced sound.
Review all connection options for both your LG television and Vizio soundbar. As long as the devices include common ports such as HDMI ARC, optical audio, or Bluetooth, they can interface successfully.
