Pedazo, I’m sorry to hear you’re not fully satisfied with the DU6900 TV’s picture quality. If the image is too dim, try adjusting Picture Mode, Contrast, Brightness, or Sharpness settings. First, let’s ensure you are running the latest Firmware Update. Go to Settings> Support> Software Update. Next, If the colors on your TV are correct but just a little too dark or bright, you can try adjusting Picture Modes, Contrast, Brightness, or Sharpness settings. For darker scenes, I recommend Dynamic Picture Mode, which makes pictures brighter and clearer in bright viewing environments. Go to Settings > All Settings> Picture > Picture Mode > Dynamic. Or you can manually adjust the Brightness by pressing the HOME button on your remote, then navigating to Settings > All Settings> Picture > Expert Settings. You may also want to disable Power Saving Mode, which automatically adjusts the brightness to reduce the TV’s power consumption. Go to Settings > All Settings> General > Eco Solution> Power Saving Mode. I hope this helps to improve your picture.
