The title says it all.
My personal favorites are:
Killer Queen (TOTP)
Don't Stop Me Now
Save Me
Crazy Little Thing Called Love
Somebody To Love
Tie Your Mother Down
Good Old Fashioned Lover Boy
Radio Ga Ga (the best one in widescreen)
I Want To Break Free
Breakthru
Scandal (don't like it too much)
Who Wants To Live Forever
The Miracle
It's a Hard Life
Las Palabras De Amor
Hammer To Fall (Looks incredible in letterbox)
Princes of the Universe
Back Chat
All the other videos look crappy.
4k televisions are just a gimmick at the moment and before long something else will take over so unless Queen Dvds are updated they will look kind of bad.
@Benross; I think gimmick is the wrong word. It's just the current state of progress in televisions. And the speed of progress of any technology has drastically increased over the years. Now and in the future upscaling techniques embedded in televisions will also progress to include A.I. and deep learning which could increase image quality of old SD (DVD) quality video.
Having said that.. new scans of the original footage/negatives is what we need in any case.
