After upgrading to Windows 10 from Windows 7 suddenly my Dell 2715K no longer displays any sort of picture until after Windows 10 boots and displays the login screen. this only happens when trying to drive the monitor at 5K using dual display ports. If I am on the mini-display port only using 4k I can see the boot process.
I believe this is some sort of clash with the EUFI boot process but would like to know if there is any sort of workaround or if a fix will ever be made available.
