Sony never fixed the blur issue in their X900H TV. It was advertised as supporting 4K120.<ref>https://web.archive.org/web/20210111215436/https://www.sony.ca/en/electronics/televisions/xbr-x900h-series/specifications</ref><ref>https://www.avsforum.com/threads/owners-thread-for-the-sony-x900h-no-price-talk.3125278/page-1819</ref>
Sony claims this TV it supports "4K120" feature defined in HDMI2.1 specifications<ref>http://web.archive.org/web/20201112194107/https://www.hdmi.org/spec21sub/eightk60_fourk120</ref>, but the feature is not fully supported, at least not exactly how it's defined in the referenced HDMI 2.1 specifications nor how an average person/buyer would expect, which states that ''4K@120Hz enables ultra-fast motion UHD images to be crisp and razor sharp'' and [http://web.archive.org/web/20201106145004im_/https://s3-us-west-2.amazonaws.com/hdmi-web-shared/public-web/static-images/1080vs4Kvs8K.jpg this image] from the same source defines the 4K Ultra HD resolution as 3840 vertical pixels and '''2160 horizontal pixels''', which is crucial for this case.


Following this they decide to band-aid hoping nobody would notice by applying a sharpening filter as claimed in this article [https://videocardz.com/newz/sony-fixes-4k120hz-blurriness-on-x900h-xh90-tvs-by-applying-a-sharpening-filter]
=== The 4K120 blur issue ===
 
 
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 by 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.
