    (Windows 10) - 2nd Monitor won't turn on


    Okay I've had this problem before (with Windows 8.1) and this is generally the reason and solution (I'm using a notebook and an external display for extended desktop):

    At Location 1 I have a Dell E2414H Monitor that is 1920x1080 resolution.

    At Location 2 I have a 26" Samsung TV I use for a monitor.. I forget the resolution but it is not 1920 x 1080.

    Neither supports the other's resolution so the first time I plug into the other display I have to go to settings and change it to a supported resolution to get it to work, however, this has always worked.

    So, the Dell monitor was working just fine on Windows 10. I upgraded a week or two ago, and it worked just fine. Then I went to Location 2 and plugged my notebook into the Samsung TV. I changed the resolution and it worked. Now back at Location #1 I plug into my Dell monitor and change it to 1920 x 1080 and it does not turn on. The monitor always says "Going into Power Save Mode" as soon as I plug it in to the computer or turn it on / off..

    Here is an interesting tid-bit that might help troubleshoot this: Windows 10 settings obviously sees the monitor is plugged in because instead of showing 1 screen in the setting it shows 2 screens and gives the normal "Extended Desktop", "Duplicate Displays" etc. etc. options. However, I'm also getting the message that there is no signal from the VGA cable.. I don't think the cable went bad nor the port on my computer. I mean the Dell monitor was working up until the second I unplugged it to go to Location 2. And the Samsung TV worked up until the second I unplugged it to go back to location 1. This is the first time I've switched back and forth between displays on Windows 10.. maybe it's a bug in the OS...

    Any ideas how to fix this?

Ok, I have it set up just like I did with Win7. Screen saver set for 10 minutes, monitor power off set for 15 minutes. The problem is, the monitor doesn't turn off! To be more accurate, it DOES turn off at the 15 minute mark, for about 1 minute. Then it turns back on and the lock screen shows. ...
