Hello Bjall, this TV uses our SmartCast Platform which offers a host of built in apps, as well as support for Google's Chromecast, Apple's AirPlay 2, and voice support for SIRI, Google Home, and Alexa. You are not able to manually download additional apps, however new apps are added to the platform often. If you find there is an app you want to watch that is not on SmartCast you may be able to cast it using Chromecast or Apple AirPlay from your phone or mobile device. If you’d like any help taking advantage of all the options VIZIO has to enjoy your content, our customer service team would be happy to speak with you at 844-254-8087.

Hello Rainbows4all, at VIZIO we pride ourselves on our highly rated picture quality. To make sure you’re getting the most out of your VIZIO TV, we’d recommend making sure your devices are connected with an HDMI cable, and are set to broadcast in 4K (2160p) or Full HD (1080p). You can also individually adjust your picture settings in the menu. For brighter rooms, try using the ‘VIVID’ picture mode for a brighter, more colorful image. If you’d like any assistance adjusting these settings, our customer support team would love to help you dial in the TV to your preference, you can reach them at 844-254-8087.
