I purchased three D-series Vizio "Smart" TV's for our motorhome in the spring of 2023. They worked well until the latest mid-2023 software update introduced "WatchFree+".
With the mandatory software update Vizio imposed on their "Smart" TV's which integrates Vizio's "WatchFree+" channel guide, conflicts are created that makes the TV very difficult to use or view, especially with Over-The-Air antenna or cable box inputs.
I've spent 2-1/2 hours on chat with Vizio tech support and have thoroughly tested all three of model D TV's based on their recommendations. The results were clear: Vizio has broken their smart TV's.
With Vizio "Smart" TV's, the only way to get effective OTA or cable channel use functionality is to re-set the TV's to Factory Defaults. Then,
NOT ENABLE WiFi Internet integration and streaming capability during the TV set-up process. This essentially "bricks" the streaming capability you may want to use through the TV. If you want to stream directly to the TV, use a Roku or Firestick.
