Sony started selling the TV with no support for 4K120 feature claiming they will implement it in the future firmware updates, which they did. However, their implementation was very deceptive towards the consumers because the effective resolution this TV can display when outputting 4K120 content is 3840 vertical and '''1080 horizontal pixels''', even though TV is reporting 3840x2160 resolution in this case.

A very simple visual inspection or a thorough pixel counting will prove this reported resolution wrong. | ||
This issue is ultimately manifested as vertical blur, because every 2 vertical pixels are duplicated instead of being unique. | This issue is ultimately manifested as vertical blur, because every 2 vertical pixels are duplicated instead of being unique. |
