What is a Vizio TV cache?

A cache is a storage solution for temporary application files such as settings, images, preferences, and other data that help the application run to your liking.

These files enhance your experience by remembering your logins, preloading common assets, and offering a quicker performance (with some limitations).

Every time you open a new app, you are loading more of these settings into your TV cache. If you commonly use multiple apps, then eventually the cache size will increase.

Once the cache is nearly full, you can experience a sluggish performance from your device, this is why we recommend the occasional clearing of your Vizio TV cache.

Why should I clear my Vizio TV cache?

The number one reason for clearing your cache is to enhance the performance of your TV.

If your TV is left running for an extended period of time, your cache becomes full of data from the apps you run and also the internet browser.

When the cache becomes full, you will experience the sluggish performance from your TV, poor streaming, and even occasional app crashes.

By clearing your TV cache on a regular basis, you ensure that your TV is running at peak performance.

You should notice the controls are more responsive and your streams perform better.

Contact Vizio Support

If none of our tips have helped in resolving the Vizio TVs’ sluggish performance, then it might be time to consider contacting Vizio support to help you troubleshoot the issue further.

Vizio may be able to advise you of other things to try or help diagnose the root cause of the issues.
