Hi Mac dogg, Thank you for sharing your thoughts on your TU690T 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 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 > Picture > Expert Settings 5) Choose a Picture Mode by going to Settings > Picture > Picture Mode and choose from Dynamic, Standard, Natural, Movie, or Filmmaker Mode. You may also want to disable Power Saving Mode, which automatically adjusts the brightness to reduce the TV’s power consumption. Go to: Settings > General > Eco Solution> Power Saving Mode.
