So I have a ASUS UX31 Laptop and I have it hooked up to an HD TV via a micro VGA adapter to the VGA port in the TV. It duplicated my desktop as soon as I plugged it in and it was going fine, then the next day I was messing around with the screen resolution and now it has stopped working. I have tried putting it pack to the other settings with no luck. It works fine if I extend my desktop to it or only display the desktop on it where my laptop screen is black. Whenever I go into my screen resolution settings (right clicking on the desktop and hitting screen resolution) I try to set it to Duplicate this display where the two monitors on screen combine with a 1 and 2 together, I then hit apply and it asks me if I want to keep these changes, I click keep changes, but then it resets to only show desktop on 1 anyway... I am very confused by this. Is there anyway to reset it to default or some other fix? If i am being unclear let me know. Thanks.
