I used to have my computer running Windows 8.1 32bit (upgraded from Win XP Pro) and both my monitors were working great with an extended desktop.
After a hard drive problem (replaced the HD), I managed to get Windows 8.1 64bit installed (after a very long and involved and difficult route now that XP is no longer supported) but both my monitors now show the same image.
Samsung 710N (recommended resolution 12080 x 1024) connected via VGA cable
LG Flatron E2240V -PN (recommended resolution 1920 x 1080) connected via HDMI cable
I have managed to change the monitor driver from Windows generic Microsoft Basic display to LG E2240V (HDMI).
But I cannot get Windows to see a second monitor as a different monitor. When I click on Detect under Display in the Control Panel, it does nothing. When I click on identify, both my monitors display a 1.
I have tried:
* http://www.eightforums.com/graphic-cards/33996-windows-8-1-cant-do-extend-display.html
* unpluging each monitor in turn from the computer and from power and waiting a couple of minutes then plugging in and booting up.
* Unpluging each monitor in turn from the computer and from power and waiting a couple of minutes then plugging in again while Windows was running.
* Doing a full shutdown before restarting to see if Windows would pick up both monitors
* Looking for new drivers from Samsung's website and LG's website.
* Trying to install drivers that were not specifically designed for Windows 8.
What else can I try?
Forgot to say - just using onboard graphics. Motherboard is Gigabyte 880GA-UD3H
