The deduction is available for the fact that the monitor does not notice, in which channel it is last operated. In addition, he needs to start long. The result is that my PC already shows the Login Screen (for SSD), and I only have to turn on the HDMI channel to see the image.
The one day I have to wait longer for the monitor to boot than on my PC, I did not think until then.
I have to keep him still and therefore forgiving 4 **** :)
