Windows 7: After Windows update 2nd Viewsonic monitor will no longer display

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!!

KChristians, welcome to the Seven Forums.

Sounds like you have WU set to automatically download and install updates, and it updated either the video or monitor driver. If that is what happened check your update history and you can uninstall it from there and should get you back to the previous drive.

Also if that s what it was you might want to set WU to not download and install drivers automatically, step #4 here,

Not working --

Uninstalling the update was the first thing I did before I even posted but unfortunately that did not help. Any other suggestions???

Not sure where to find it or how to do it. Monitors didn't come with disks.

Was it the monitor or the video driver that WU updated?
