Thank you, Khaled419! We love to hear positive feedback and we’re delighted you’re enjoying your new Samsung TV. 

Paul: Thank you for your review of the Samsung TU7000 TV. I am sorry you are finding your image to be too dark when watching Netflix HDR movies. Your TV supports HDR allowing you to enjoy a wide spectrum of colors and visual details, even in dark scenes. It automatically matches the dynamic range of the content to the TV on a scene-by-scene basis to maximize the capabilities of the TV, providing the best possible picture. To check, go to Settings > Picture Mode. The icon in the Quick Settings Menu will change to show the “HDR” on it. If you’re watching a streaming app, give it some time for the Internet to stabilize for UHD & HDR signals. You can also manually adjust brightness by going to: Home> Settings> Picture> Expert Settings> Brightness You may also want to adjust the Contrast, Sharpness, Color, or Tint (G/R) in the Expert Settings. I hope this helps to solve your issue.
