Hi,

So I have had a dual monitor setup for a while now, one monitor via HDMI, and one via VGA (because it is an old-ish monitor and doesn't support HDMI).

All of a sudden today the VGA monitor has stopped working. When I turn on my PC my main monitor (HDMI) is working fine, however my second one isn't. The second one (VGA) turns on and shows the "on" light however is just blinking at me, and will sometimes flash part of the screen for a second and will disappear again.

What is the likely cause of this and are there any fixes? I find it strange that all of a sudden the monitor decides to not work, and am pretty sure its not to do with the monitor itself, as it is fully functioning etc.

Any responses to my problem are appreciated.

Kind regards,

Alex.
