Is it just me or do you agree that 1080p video looked awful when being seen with a 27” iMac? I went to BB and view some HD trailers from iTunes like Baraka and Finding Nemo. The movies looked soft. They are actually much sharper with my 12.9” iPad Pro. Is it because the movies need to be scaled up 7 times their original resolutions? How about standard 480p? How bad does it look like when watching standard definition video with a 5k monitor?
