Hi. On my Hisense 65" H9F, the picture clarity and quality looks fantastic when streaming Netflix videos with the built in Apps over wifi. However, for some reason the clarity and sharpness of HD cable channels coming from my Fios box, appears more blurry and pixelated than native Netflix App content. Also on Fios channels, "Color Space" is fixed on auto, and doesn,t let me select native. HDMI dynamic range is fixed, and color tempature does not allow me to select "mid-low" setting. I am using a HDMI 2.1 8K cable which is backward compatible on the Fios box, and video output is 2180p resolution. Also, I was forced to upgrade the OS from the factory installed version, and after a reset it still remains on the latest version. I have no idea how to get the OS back to the factory default for comparison testing. Does anyone have an idea what is causing the difference in clarity and pixelation, and how to fix it?
