The purchased 1 year warranty on this XPS 8900 expired on December 10, 2016. The main problem is when trying to use multiple monitors the XPS 8900 can't pick up the other monitor in the settings, but the monitor is still receiving a signal from the XPS 8900 as it's a different shade of black that is on the screen. So I'm left with one monitor having a constant black screen. I have troubleshot this myself for hours attempting to locate the problem and I have found that the graphics drivers on my computer aren't allowing the connection as there is a problem with them. Both monitors are connected via HDMI cables.

My troubleshooting:

• Restarted my computer
• Shut it down
• Shut it down via plug
• Switched HDMI cables
• Re-installed related drivers
• Troubleshooting software

And still no fix. But when looking at my graphics drives I found this there is an issue with the display adapter drivers. But reinstalling them changed nothing until I reinstalled the monitor driver this fixed both monitors for a split second, then left me with a frozen black screen with a frozen loading cursor on the screen. 

I'm still trying to fix this problem, and possible solutions would be welcomed as the broken display adapter drivers are causing the overall performance of the computer to suffer.
