This may be a duplicate of this post, though the answer there doesn't help.

My monitor will "blank" (disconnect-ish) from my computer after maybe 2 minutes of idle.

  • The monitor light still signals that the screen is on.
  • Moving my mouse or keyboard does nothing.
  • Putting my computer to sleep (with the power button) and the monitor responds showing that it's been disconnected. I then press the power button again to wake it and works normally.
  • Clicking the button on the monitor (switching input and then switching back) will "wake" it up.

I've always had an issue where my monitor would blank after 2 minutes (even though my screensaver was set to 10) and when I pressed on my keyboard it would wake it, though it would take a couple seconds to respond (and I would quickly enter my pin, only to re-enter it because it didn't all get entered).

Lately (last week or so), it won't even respond to my mouse or keyboard.

Note, the computer isn't going to sleep - I disabled it. Also when it sleeps my monitor shows it isn't connected.


My monitor is: Samsung IT LC24F390FHNXZA 24"
My computer is: Intel NUC mini PC kit NUC7i7BNH

My power options are set to maximum performance in all.

  • Fairly sure its a nuc/intel problem. The gpu/driver is what takes care of displaying stuff on the monitor. You can make sure Windows is updated and the gpu driver is updated. I think besides that you need to talk to intel. I do not think this is a monitor problem but maybe its possible. Testing a 2nd monitor would answer that. – CmosBattery Mar 6 '19 at 5:08
  • @CmosBattery I'm assuming it's related to my computer, because I've always had the issue with the Mouse and Keyboard delay after only a couple minutes of inactivity. – WELZ Mar 6 '19 at 12:24
  • Well, you would have to ask if they all do that of that product. When you resume/go to login or whatever there's going to be some point where the accessories input might get delayed.. if the computer is busy. – CmosBattery Mar 6 '19 at 15:39
  • Maybe you should check for a bios update or switch out the hdd/ssd and try a new os install. For all I know you need it. The accessories are attached vis usb which is bios/hardware/driver. And then you have possible os problems after that. – CmosBattery Mar 6 '19 at 15:41
  • I recently updated bios, I have an ssd. Entire build is less than a year old. :S – WELZ Mar 6 '19 at 15:43

Try updating your HDMI firmware. This is separate from the BIOS firmware and this update is not detected by Intel's driver update utility.
