Hello Dianna, 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. 

Hello Hf, sorry to hear you are not having a smooth experience. I would love the opportunity to have our technical support team learn more about the issues you are experiencing. When you have a free moment, they’re available through text message, chat, or over the phone. Just go to support.VIZIO.com and click on ‘Contact Us’.
