      Subsampling   Visual impact
PC          4:4:4   Major
Movies      4:2:0   None
Video games 4:4:4   Minor
Sports      4:2:0   None
TV Shows    4:2:0   None

Artifacts from chroma subsampling are at their most noticeable with text atop a flat color. The impact is far less visible in videos and photos. This matters when connecting your TV to a computer as you don't want your text to be blurry to the point of being unreadable.

As you can see, the lack of detail is clearly apparent in the bottom two rows. The text is all muddled together, and a lot of it is completely unreadable. While 4:2:2 fares better than 4:2:0, it still isn't what most would consider acceptable. While this pattern showcases an extreme case, similar side effects are visible in normal usage as well. It usually makes standard text look fuzzy and reduces its clarity. It's also important to note that subsampling on a PC requires using the YCbCr/YUV format as RGB does not support it.
