Windows 10: Unable to reset display settings

A family member recently 'changed something' related to the Windows 10 display settings (don't ask !)
Ever since the PC boots into Windows and shows a black screen.
I'm reasonably technical and have tried some things I've found by searching, but nothing works.
I can boot into Safe Mode with low resolution, but changed display settings are not saved when the PC is rebooted.
System restore points, etc have all failed.
I've connected to alternate monitors and they show 'Out of Range', but again I can do nothing but boot into Safe Mode.

I'd be quite happy doing a regedit if I could find where windows stores the display adapter settings, but so far I've been unable to find where these are stored.

Does anyone know how I can boot into Safe Mode and then update things so when Windows restarts normally it just uses some really basic display adapter settings / low resolution ?
...seems like it should be an easy thing to do but I'm pretty close to just giving up and reinstalling (I really don't want to do this ! )

How to factory reset Cisco 1700 Router

Hopefully I can help you here....its a very common thing to happen.


First, I take it you dont know the passwords for console access or telnet/ssh?

I will assume that these devices belong to you.

step 1. Plug a cisco console cable into a serial port on your pc
step 2. Plug other end into Cisco console port
step 3. Using hyperterm or putty or similar connect to the serial port
step 4. boot router, and make sure you clearly can see the output (this confirms you have good serial comms)
step 5. if this fails, adjust the comm port settings (9600, 8,1,n are the default)
step 6. now you have to do the only hard part...send the break command:

Break command list: Break Commands

Go down the list and match your OS and SW and try the sequence suggested.

If this fails several times do what I do: Install putty (free) and then to send a break so you can get into rommom just hit "ctrl-a b".
