Make sure to check your TV settings to confirm that it is set to display the highest resolution available, and ensure that you're using a compatible HDMI port on your TV that supports UHD (HDMI 2.0 or above). If everything is set up correctly, you should have a great UHD viewing experience with your Sky Q and Panasonic TV.
