You would have scaling issues there too, because scaling a 720p signal
to 2160p would have to create pixles "out of nowhere", which is only
just asking for noise. Sadly, there is no perfect solution other than
a display that can output at whatever framerate it is given and for
all sources to be of the same pixel resolution. I vote 1080p for
everything ;-)
