Windows 10: Easy fix for black screen on HDMI monitor after update.

Shutdown everything. Don't just switch your monitor off. Unplug it and plug it back in. Presto, problem solved.

External Monitor is detected, but black

My monitor was working perfectly this morning. I left for lunch and came back to a black screen. I've tried installing updates and the hdmi cord, but nothing has fixed this.

The monitor is detected, as I can drag windows over to it. It's just black. Any suggestions?

 

Laptop monitor is black but HDMI to TV works

So, I seem to be having the opposite problem of most. After updating my laptop to windows 10 the laptop monitor basically does not work - it's as if the graphics card does not see it. When I turn the computer on it shows me the dell logo with options to
open the boot settings, and it starts to show the graphics for loading windows and then just goes to a black screen. Like others I thought maybe it's the issue with thinking there's 2 monitors when there really are not because it's acting like my dual monitor
work computer at start-up, but none of the listed fixes worked. I tried to plug the computer into the TV via an HDMI cable and that does work but the laptop monitor goes from a 'light' black to an 'off' black. Of course the computer at that point only thinks
there's one monitor which is the TV when I go into the settings. I've tried every combination of plugging in and pulling out the HDMI at different points in the reboot process but I always end up in the same place of having to plug the laptop into the TV to
use it. It's as if the Intel graphics doesn't see the laptop monitor as an option. I also tried to update the graphics drivers but it says there are no available updates. Anyone else have this problem and a suggested solution so I can move my laptop away
from the TV?!

 

Black borders on screen

Hi Lyn,

It is true that the challenges that you’re having with the black borders on your computer screen might be related to the Display Settings of your monitor just like what DaveM121 was suggesting. To better assist you with your concern, we need you to answer
the following questions:

• Which type of display cable are you using? ( VGA, DVI, HDMI cable).
• Were you able to update your display adapter drivers?

Looking forward to your response.
