Currently I have an LG monitor running a PC via DisplayPort.

Just bought an old office PC to convert to a Home Media server the only output is VGA. The PC boots as I can hear the USB sound when plugging in peripherals and Mouse/Keyboard light up.

However no signal is showing on the monitor. I have used both VGA to Displayport and VGA to HDMI. I know the monitor and ports work as it used for my main PC. So far I have:

  • Powercycled the monitor.
  • Left the PC to POST.
  • Reset the monitor.
  • Used an old mobo kit with both onboard and discrete graphics.
  • Plugged and unplugged multiple times.
I don't want to buy another monitor as I am planning to run a headless media server.

Anything else I can do?

As I said the PC works fine as I can hear it posting and the peripherals light up no problem. I also know the monitor works fine as I can display my main PC via HDMI and DP.
