I do not even understand how previous users were not able to notice. Similarly, I also will complete by saying that there is indeed a difference between picture and sound. Although minimal, less than a second, but enough to be noticeable. To watch TV ca can pass, but it is very inconvenient for those who need a short lag time as musicians. I wanted to use to connect my electric piano to my speakers.
In short, very disappointed and now very suspicious of the opinions given by other 'users' ...
