Hi Christy, Thank you for sharing your thoughts on your CU7000D TV’s image quality. The TV will upscale as best as possible any content sent to it. The closer your content is to 4K, the better the image will look on the screen. Here are some tips to help improve picture Sharpness: 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. Should you ever have questions or need help with TV features, specs, or operations, we are here to help. You can call us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week.

Hi Nath, We appreciate your feedback on the Samsung CU7000 TV. I'm sorry to hear you are experiencing issues with your Wi-Fi being slow and the YouTube app not performing well. Please try the below troubleshooting steps to help resolve these issues. First, let's ensure you are running the latest Firmware. Go to Settings> Support> Software Update. To ensure you do not miss any Firmware Updates, I recommend enabling Auto Updates. Go to Settings> Support> Software Update> then select Auto Update. Next, let's try running a cold boot on your TV. To do so, hold down the Power button on the Samsung TV remote until the TV turns off and then on again. This should take about 5 seconds. I hope these tips help resolve your concerns. If you need more help, Samsung is here for you. Please call us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week.
