Please check the cables connected between your CPU and monitor are not broken and fixed correctly. If cables are ok and connected correctly, check if CPU is running. All new monitors are capable of detecting input signals from multiple sources, if only one signal source is present when monitor is powered on. Else manually change which source to be used by monitor for display.

When you use a VGA cable coming out of the monitor, the monitor is giving out an analog signal through the VGA connection. For the monitor to give out a digital signal, you need a DVI or HDMI cable. The VGA to HDMI cord just converts the analog signal into a digital signal so it's not completely useless, however the quality will not be as good as an HDMI to HDMI or DVI to DVI or HDMI to DVI
