Display port not working after updating to win10

[Kylothian]

Morning Guys

Last night I have updated my laptop (Alienware mx17r3) to Win 10 Tech build 10041, updated all my drivers now my display port is not working, When booting I can see it showing BIOS and post screen but once I am in windows just goes dead with a msg no display port detected. Running my laptop screen, dell ultrasharp-u2913wm (Display port) and dell S2340L (VGA) port. On VGA both screen works fine no problem but as soon as I try running on display port dead as a doornail. I checked device manager its not even detecting the 3rd screen. Have updated latest drives from intel and ran windows update but to no avail. Not sure if I am missing something silly here or if anyone have similar problems, have read other forums they mentioned was something to do with power settings after changing all that still same problem,

thanks for the time

regards

Energy saving mode enabled?

 

AMD CCC (since I think that model has AMD) detect the DisplayPort at all?

 

Try just the DP monitor and not the VGA one. Does that work or still no?

quick update, ran sfc scan found some problem, sfc phone. ran dism /online /cleanup-image /restorehealth then sfc all went smooth got that working. Did intel update and sigh sitll no change

 

My model runs Intel/Nvidia Graphics. Going to download the intel gpu utility app and try that. Currently just the monitor is plugged in on dp, VGA is unplugged only detects my laptop screen no second screen.

 

Will report back shortly

bleh okay no change no luck updated all that is a driver, vga works fine but for the love of me cant get DP(if you laugh you are immature...although i giggled a bit:P). Although I see as soon as I plug in the cable it tells me. Entering Power Saver Mode. Does not even detect the monitor under device manager, VGA works fine.

 

At this pace Im going to reinstall windows and go back to windows 8.1 and wait until windows 10 is released

Try this and see if it helps.

 

1. Click Start > Run.
2. Type cmd and press Enter.
3. At the command prompt, run this command: Note: In Windows 7 and later, open the command prompt using the Run as Administrator option.
   • set devmgr_show_nonpresent_devices=1 Note: If this command does not work (a possibility in Windows Server 2000 and 2003), you may need to add the parameter to Windows and set its value:
     1. Right-click the My Computer desktop icon and choose Properties.
     2. Click the Advanced tab and select Environment Variables.
     3. In the System variables section, click New.
     4. Set the Variable name to devmgr_show_nonpresent_devices and set the Variable value to 1 to enable the parameter.
     5. Click OK to add the variable to Windows.
4. Start the Device Manager by running this command from the same command prompt:
5. start devmgmt.msc
6. Click View > Show Hidden Devices.
7. Expand the Monitors tree (click the plus sign next to the Monitors entry).
8. Right-click the dimmed Monitors, then click Uninstall.
9. Once all of the grayed out Monitors are uninstalled, reconnect your monitor.

Thanks BP9801 one of the very first things I tried but did not want to work. Lol Braegnok when it comes to computers nothing surprises me I'm willing to try everything,

 

but after 2-3 hours of more struggling I decided screw it to much headachiness formatted with windows 10 half my drivers refused to work went back to windows 8.1 now my machine is working 100%. I will wait a few months until windows 10 finally releases. One thing that I did discover is when I booted windows 8 screen still showed Entering energy saver mode, after all drivers was updated and pending reboot I unplugged the power of the screen rebooted as the pc came back online I plugged in the power and the screen came back online. I did not think to do the same for Windows 10 ( it was a long day don't judge me )

 

Thank you for all the help, im tempted to become an amish farmer without tech seems easier

 

Thanks again

I am pretty sure this is a problem with the driver not being fully tested

I believe I have heard of this problem before, you should check at guru3D
