About TV Firmware:

By upgrading your TV firmware version, you will benefit from improved image quality, fixed various noise issues, enhanced Internet connectivity (if available), boosted stability and usability level, as well as from several other changes.

However, you should first check that this release is compatible with your TV model and that it specifically resolves a problem that you have been encountering or makes changes that you deem useful.

In addition to that, since there are numerous TV models and manufacturers, as well as several methods for updating the software version, we recommend that you refer to the product guide, familiarize yourself with the procedure, and initiate the upgrade only when you have completely understood the steps.

Bear in mind that, in the event of an update failure encountered by trying to apply an improper firmware or if you don't successfully succeed to install the new software, the TV can suffer serious malfunctions.

Therefore, if you wish to apply this release, click the download button, get the package, and refer to the update guide to upgrade the TV firmware. Also, if you want to stay up to date with latest releases, check with our website as often as possible.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
