After unscrewing and opening the upper shell, place the device so the CATx connectors are on the right and the electrical
connectors are on the left. The main circuit board then will look like this:

Selecting the moment to switch to the next frame
The transmission of screen data is not synchronous to the screen change of the graphics card. Normally, the transmission is
terminated while a frame on the screen is displayed. If the device switches to the new frame while the old frame is being
displayed (somewhere on the screen), it is possible that you will see horizontal screen breaks during the switch.
terminated while a frame on the screen is displayed. If the device switches to the new frame while the old frame is being
displayed (somewhere on the screen), it is possible that you will see horizontal screen breaks during the switch.
On the other hand, the device must idle until the frame is displayed completely (until VSYNC) -> at which point the number of
frames per second transmitted may be reduced significantly. In this case, it is possible that you will see a stepping of the frames.

Higher frame rate, but horizontal breaks may
possibly be detectable.
Lower frame rate, but no horizontal breaks
detectable; possibility of stepping pictures.
