I need to switch my monitor from using VGA to HDMI. It is one monitor, not two. Currently, it is using the VGA port. I want it to use the HDMI port. Unplugging the VGA and plugging in the HDMI cord does not work. It will be black until the VGA is plugged back in. The monitor port and the HDMI cable are fine (they work with consoles). I assume this is only a problem with driver, windows, or bios settings Any help would be greatly appreciated.
