Hello Steven, 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. 

Hi there Raogo, this is indeed possible by customizing your app row, you can find more information on this by searching "How to Customize your App Row" on the support.vizio.com website. If you're still having a hard time with that, I would like to offer the assistance of our award-winning technical support team with this issue. Please visit support.VIZIO.com and click on ‘Contact Us’. We’ve got agents ready to chat, text message, or speak with you on the phone.
