HTS must be more then width, so the 1080 value clearly is wrong, this is then corrected with some weird math dividing clocks in to_pixels_per_line() which results in the hts getting multiplied by 2, resulting in 2160. Instead just directly set hts to the correct value of 2160 and drop to_pixels_per_line().
