Having now played about with my U8QF am very happy. SD is okay obviously this is very dependant on the quality of the original. HD is very good and the 4k is stunning, well I would hope it would be never having experienced it before. One point of note which is mentioned in this review of the U7QF is the viewing angle. Stated anything over 20 deg off axis results in noticeable degredation well I must say I have not noticed it that bad. I can sit 45 deg off axis and find the picture satisfactory, certainly watcheable without a doubt. Finally I like the remote is silver but does not look like a bit of plastic sprayed silver.
