Windows: This helps when the screen has no signal

If the screen of your Windows PC has no signal, this can have several causes. First, check if the screen is properly connected to the PC and all cables are firmly seated in the connectors. If this is the case, please continue as follows:

1. Make sure that the screen is connected to the power supply and switched on.
2. To rule out a defect in one of the connection cables, take another cable as a test and connect the PC and screen to it.
3. If the screen can be switched on but remains black, it may be that you have selected the wrong source. To switch between the different inputs, please press the appropriate button on the monitor.
4. Sometimes a defect in the graphics card is also the cause if the screen has no signal. To check this, simply connect the screen to another port of the PC.
