Selecting the moment of switching to the next frame
The transmission of screen data in not synchronous to the screen change of the graphic card.
Normally, the transmission is terminated during displaying a frame on the screen. If the
device switches to the new frame during the displaying period of the old frame (somewhere
on the screen), it’s possible, that you can see horizontal screen breaks in the moment of
switching. On the other hand the device must idle, until the actual frame is displayed
completely (until VSYNC) -> the number of frames per second transmitted sinks.
Moment to switch JP3 behaviour
