Thank you for sharing your thoughts on the picture quality of your TV. To ensure you’ve got the latest image quality updates, please confirm that your TV is up to date with the latest firmware version. You can check by going to: Home > Menu > Settings > Support > Software Update. If the picture you’re seeing is still not to your liking after updating firmware, there are several picture settings you may want to try adjusting. Go to Home > left direction button > Settings > All Settings > Picture > Picture Mode ...and select the mode that best fits your usage: 1. Standard: Is the default mode suitable for general viewing environments 2. Dynamic: Makes the picture brighter and clearer in bright viewing environments 3. Eco: Provided to save energy 4. Movie: Suitable for watching TV or movies in a dark room 5. Filmmaker Mode: Provides source content just as the creators intended. If the image is defined as Filmmaker Mode, it’ll automatically switch to Filmmaker Mode while watching. You can also fine-tune your picture with expert settings such as brightness, contrast, sharpness and more (All Settings > Picture > Expert Settings). There are also several sound settings you can adjust to suit your personal preferences. • Sound Modes may better meet your personal preferences. Go to: Menu > Settings > All Settings > Sound > Sound Mode, or Expert Settings to fine-tune and customize your sound. • Adaptive Sound will also further optimize sound quality by analyzing the viewing space and the acoustic components of the content. Go to: Menu > Settings > All Settings > General & Privacy > Intelligent Mode Settings.
