JAB00: Thank you for purchasing the Samsung TU7000 and for your review. We value your feedback regarding your TV's picture quality. There are several settings you can adjust to your liking such as Picture Mode and Expert Settings. Please see this guide for complete details: https://www.samsung.com/us/support/answer/ANS00079295/ There are several preset picture modes and many custom settings that can optimize image quality for your viewing scenario. Go to HOME > SETTINGS > PICTURE > PICTURE MODE and choose: 1) Dynamic: Makes the picture brighter and clearer in bright viewing environments. 2) Standard: This is the default mode suitable for general viewing environments. 3) Natural: Reduces eye strain for a comfortable viewing experience. 4) Movie: Suitable for watching TV or movies in a dark room. 5) Filmmaker: Watch the source content (e.g., movie) as it is. In addition, the image quality on your screen depends on the source and the connection. HDMI cables are recommended for optimal HD viewing; and when possible, 4K content will provide the best picture quality. The TV will upscale as best as possible any content sent to it. The closer the signal is to 4K, the better it will look coming out. The quality of the streaming content depends largely on the speed of your internet, as most content providers have adaptive streaming that will automatically adjust the image quality based on the network bandwidth. We also recommend you check that your TV is running the latest firmware. Using your TV's remote, navigate to Settings, and select Support. Select Software Update, and then select Update Now. New updates will be downloaded and installed on your TV. Updates usually take a few minutes; please do not turn off the TV until the update is complete. When the update is finished, the TV will restart automatically. If there aren't any new updates, select OK to exit. You may want to enable automatic updates for conveniences. Select Settings- Support- Software Update, then select Auto Update.
