Sometimes, we get 4K footage to check playback.
If everyone have 4K or 5K monitors, we can check pixel by pixel.
But a lot of users still have typical HD monitors.
In Switch, there are "Zoom Out" and "Zoom In", but it depends on monitor size.
When I have 4000 x 2000 movie file on HD monitor (1920 x 1200), Window size will be expand up to 1920 (Width) .
There is "Double size" in View Menu.
But Window size will fit up to Monitor resolution.
Sample Image for zooming.
Zoom In (such as Pixel by Pixel and more zoom)
