I'm having problems with the monitor of my Dell XPS13 laptop. It's been behaving like this ever since I upgraded to Windows 10. I never thought much of it, as switching my laptop to sleep mode and turning it on again would usually fix it.
I'm not sure how to describe the issue I'm having with my laptop, but basically, sometimes when I try to turn on my laptop, 3/4 of the screen would be black. When this happens, I can't see much on my laptop screen. I would usually apply the method mentioned above to fix it, and it would work most of the time. If it didn't, I would force shutdown my laptop, and usually 1-2 would do the trick. (I tried not to perform force shutdowns though. It's only when the 'sleep mode' method doesn't work that I'd use it)
So today, when I turned on my laptop, the issue came back, and it's much worse than before. The same screen problem happened, but my method of fixing it just wouldn't work anymore... I tried force shutting down a few times (not much of a choice, as I can't see much on the screen) and turning my laptop back on, but the issue just wouldn't go away.
I don't really know how to go about fixing this, so I would really appreciste it if anyone here could help me resolve this issue. (I know force shutting down is bad, but I'm at my wit's end )
Update: My screen is almost back to normal. The black area is smaller; it can be found at the bottom and it flickers.
I actually tried going to Dell's website to try out the online diagnostic tests, but they did not detect any issues; My laptop passed all of the diagnostics tests.
What is the exact system model? Did the issue start immediately after upgrading to Win10? Do you happen to use the Auto / Manual sleep mode? Does the system shutdown / restart fine?
Update the BIOS - http://dell.to/1n3X2po - enter the service tag and download the BIOS, update and restart the machine and check.
As advised by ejn63, test the system with an external monitor.
Check for distortion in diags - Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us.

Check for distortion in BIOS - Restart the system and press f2 key to enter BIOS - see if the distortion is seen in BIOS.
If the distortion is seen only in Windows, then reinstall the video drivers from the support site - restart and check.
