I use a dual monitor combination of a full HD and a retina screen.
Videos on the Full HD screen fill the entire video window and resize nicely to whatever video window size I desire.
Videos on the retina screen however show up only on the bottom left corner and make weird glitches when resized.
Full HD 27"
Macbook Retina 15"
Resizing glitches on Macbook Retina 15" (works fine on the other screen):
P.S.: the scope and analyzer have nothing to do with this. They just happen to be in the first video I could grab.
