    Cannot extend the monitors on new install


    Because of a crash, I am in the process of re-installing 8.1. All is well except, my 2 monitors are not recognized in device manager. Only 1 PNP monitor is recognized. Scan for hardware changes makes no difference. If I disconnect 1 monitor, W8.1 will recognize the connected monitor by brand name, and same for connecting/disconnecting the other, but not when both are connected. One is DVI and the other is VGA. Detect didn't find another display, yet both monitors are in the mirror mode. This setup works fine with all the W10 builds I have been testing on this machine and was fine before 8.1 decided to not boot/crash a couple of days ago. Appreciate any suggestions.

    I just reinstalled the whole system again and both monitors are recognized as previous. Why the 1st reinstall did not work is unknown. I seem to be having an awful large amount of Win updates to deal with. One was 117 and after install and did a windows update check 28 more, last update was 13.

    I am still working with the original 8.1 install SSD, but it is in a loop trying to boot and then restart.
