Hi Vivian, Thank you for sharing your experience with low volume. There are several volume features you can adjust, which may improve your audio experience. 1) Auto Volume automatically adjusts the sound to a certain level when changing channels or switching to another external input. Go to Settings > All Settings> Sound > Expert Settings > Auto Volume. 2) Adaptive Sound automatically adjusts to a specific volume level while watching TV. The TV analyzes your volume usage history by time period to automatically adjust the volume when you use an app or switch to an external input source. Go to Settings> All Settings> Sound> Sound Mode> Adaptive Sound. 3) Several Sound Modes are likewise available to meet your personal preferences: Home > Settings > All Settings> Sound > Sound Mode. Also, some sources have their own volume control, which might need to be set higher. Please check the volume control of the external device (cable box or satellite box, DVD, Blu-ray, etc.) connected to your TV. Also, check the cable connection between an external device and the TV and then try the cable connection again. If you need more help, Samsung is here for you!

Hi Easy Riter, Thank you for sharing your thoughts on your DU7200 TV’s image quality. The TV will upscale any content sent to it as best as possible. The closer your content is to 4K, the better the image will look on the screen. Here are some tips to help improve picture clarity: 1) HDMI cables are recommended for optimal HD viewing. 2) If you have an analog cable box or satellite box, upgrade to a digital cable box or satellite box. 3) Change the output resolution of your devices, such as digital broadcast receivers, IPTV, and set-top boxes, to UHD or HD. 4) You can further adjust your sharpness, brightness, contrast, color, and more by going to Settings > All Settings> Picture > Expert Settings 5) Choose a Picture Mode by going to Settings > All Settings> Picture > Picture Mode and choose from Dynamic, Standard, Natural, Movie, or Filmmaker Mode. 6) For optimal motion image performance, you may want to adjust the picture clarity setting by going to Settings > All Settings> Picture > Expert Settings > Picture Clarity Settings.
