Hello Anonymous! I spent a great amount of time trying to find an answer for your question. I entered several search terms on GOOGLE and YouTube for this topic--among them => "Is 4:4:4 Chroma Subsampling compatible with 1080p HDTV sets" and "4:4:4 Chroma Subsampling." I really believe that the entry entitled "Chroma Subsampling 4:4:4 vs 4:2:2 vs 4:2:0" which is located on the website RTINGS.com gave a lot of insight into this topic and I ask that you check it out--after entering the search term "Chroma Subsampling 4:4:4 vs 4:2:2 vs 4:2:0" into the GOOGLE search bar. It indicates verbatim and in part that "color subsampling is a method of compression that greatly reduces file size and bandwidth requirements with practically no quality loss. Unless you are going to use your TV as a primary PC monitor where lots of text is going to be read, there shouldn't be a need to worry about it." This aforementioned entry also shows which types of viewing that subsampling has the most impact on and the degree of that impact in categories such as PC use, movies, video games, sports, and TV shows. I "did" notice that the only types of televisions which were mentioned in this entry (to the best of my knowledge) were 4K television sets.I am sorry that I did not have a better answer for you Anonymous; however, you might want to phone Insignia tech support at 1-877-467-4289 between the hours of 8:00 A.M. and 9:00 P.M. Central time seven days a week and ask them for an answer or someone at Best Buy's home theater department who is knowledgeable about this matter.
