check your cable got plug in correctly or lossen.. go tighten it
so the problem lies solely wif the cable? not other problems of video/graphic or whatsoever?
If you connect it to other monitors and still no signal, it could be the video card, the mainboard, or the video cable.
VGA cable connection pins can bend or even come off if handled improperly.
Graphics card, cable, motherboard can all cause problems. It could be the monitor itself.
