After Windows update 2nd Viewsonic monitor will no longer display
Just performed windows update on my Dell Inspiron Desktop 560MT - Intel(R) G45/G43 Express Chipset. I am running Windows 7 Home Premium - 64 bit. I have been using dual monitors on the system since purchase. After performing windows update today my second monitor (connected by HDMI) will no longer display. The other monitor (the working one) is connected via VGA. The system does not recognize it is even connected. At start up however it will display up until login window. I am using two ViewSonic VX2453 Series monitors. I am desperate as I have to have both monitors for work. I have tried unplugging and replugging, restarting it with it unplugged and plugged. I uninstalled the update and have tried autodetect on the system all to no avail. Help!!
