i was having the same problem, and i found my fix... turns out i was using slideshow for my background as well as lock screen...
turned that off on both, and POOF now the screen sleeps again!
Just because it was not mentioned here, I have solved my problem and the solution was not posted anywhere. My issue was with a programme that prevented the monitor from turning off. It's DS4Windows. The tool that allows you to use your PlayStation controller with Windows over bluetooth. You can't leave that tool just on, you have to hit "Stop" when you're done.
I tried many solutions posted on TenForums which did not work on my Windows 10. A promising one was LCD.exe (found by googling "turn off LCD.exe"). It worked fine for a while and created a very dark screen, but then occasionally would not resume without a cold power-off reboot. What finally worked is to set the Screensaver to "blank" and create a desktop shortcut to C:\Windows\System32\scrnsave.scr.
My problem is the very opposite, my monitor allways goes blank when the computer is innactive for 5 minutes, and i can't get it to stop doing that, messed in the configs in the monitor benq2430xt, changed to never goes OFF
In windows 10 i did the same thing in two different places(power management and monitor options) and it didn't help.
Still no fix, I presume? I'm having the same issue. I'm using three monitors and often leave my desk for a while just to come back and monitors are still on...it's driving me nuts.
Edit: Closed out Google Chrome and my Corsair program and now it's working just fine.

Hi everyone, same problem here upgrading from win7 to win10
in my case at the extabilished time the ""shutdown procedure"" of the monitor starts correctly, the display show me for a second "no signal" that is correct (the same in win7 that worked fine) and then just a millisecond after the monitor don't turn off but it seems that detects immediately a signal from hdmi input and is stays turned on
my video setup.. sapphire amd radeon R9 380 dual-x and asus vn247h monitor
i don't have usb joypad or similar plugged in
i tryed almost everything in my knowledge and found that using an hdmi -> hdmi cable the turn off function works fine
my setup was hdmi -> DVI cable (boundled with my asus monitor). don't know why windows10 has this issue because with the same hardware (and cable) in windows7 all was working great
I had this issue, and couldn't figure out the answer. Anyways, I had a portable bluetooth speaker plugged into the USB port charging, and while it was plugged in my computer would not sleep, and the monitors would not turn off. Anyways, I just unplugged it, and now they work as they did before. So charging this portable bluetooth speaker via USB is what was causing the problem.
