Interesting. I also noticed that when I selected the movie today which happened to be 3D it was immediate in asking me the mode I wanted. Usually it would take 5 seconds or so. I also have to try some more 4k movies on this box. It’s connected to a projector and it was always hit or miss whether a 4k movie would start properly while it was trying to adjust the refresh rate. I have a hunch this is fixed as well.
