I bought a new 2160 pixel TV. When I go the Menu, Options, and Screen Resolutions screens, it has a circle to check 720 or 1080 pixels. There is no circle to check 2160 pixels. Why? Shouldn't the Screen Resolution screen have a 2160 option? The 2160 is supposed to give four times the clarity and sharpness of the 1080. Since you don't have the 2160 option, does this mean I am not getting all of the clarity and sharpness that I paid for when I bought my new TV. Please tell how to get the most pixels. Is there another screen or do you need to upgrade your system to keep up with the new technology? Please let me know.
