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?!

 

Laptop problem: Black vertical "sidebar" [Update]

I will try that... do you think I have complete access to replace the monitor cable without dismantling the laptop from step 1? *Eek!
Tbh it's a bit scary.

Hi Frank,

Thank you for your interest in Windows 10.

I understand the you have tried to resolve the issue and tried many steps. I really appreciate your efforts in resolving this issue. As you have mentioned that switching the cables make both the monitor
work so I believe its not the driver issue. I would suggest you to try connecting another cable and check if the issue persists.

Below is the Microsoft help article on How to connect a second monitor/ Multi monitors.

Note: The steps for Windows 8/8.1 applies to Windows 10.
