Explanation

If no image is displayed on the monitor or projector, first make sure that the display device is plugged in and turned on. Check that the monitor is not in standby mode (press a key or cycle the power to the monitor to activate it). You may also need to use controls on the monitor itself to adjust the image or select the appropriate data source or input channel. For example, if there is no image on the screen, check that the monitor is set to use the HDMI port that the computer is connected to, rather than an empty DVI port. These o n-screen display (OSD) menus are operated using buttons on the monitor case. As well as input control, you can usually find settings for brightness, color/contrast, and power saving.
