Hi, my X1 Yoga Gen 3 has a WQHD internal display and my external TV is 4K. I found that I need to rescale the size of Windows and browsers often when dragging them back and forth across the two screens. I don’t recall clearly but I think I did not have to do such resizing when I was using a X1E with 4K internal display. Am I correct that if both laptop and external display have the same resolutions, there is no need for resizingas the mapping is 1:1. Otherwise, need to do the inconvenience of scaling.
