Can't picture out anything on garbled laptop display

[elyn03]

I cannot picture out anything on my laptop screen after selecting 'microsoft basic display adapter' to update driver software of display adapter from the device manager. I did this as I was trying to fix my issue with brightness control (cannot decrease nor increase it). After I select that option my display went black, no actual display at all so I shut it down, maybe i shouldnt have since the driver might have been still updating?

Anyway, laptop is still working, I tried running devmgmt.mcs by typing windows+R, then clicking the arrows hoping it would get to the display adapter and hoping I could update the software by clickng the right click option in the keyboard but I cant really make sense of what's really happening in the view so I end up just shutting it down and restsrting using the alt+f4 option.

I've connected it with an external monitor (vga connected) and trying my luck with the FN+display option but didnt work. Nothing was displayed in the external monitor.

Laptop is samsung, 4yrs, 36bit, 2gb ram, running on windows 10 (the free upgrade).

Havent brought to a tech shop, will do if I can't manage to solve it by reading online. Ive thought of using safe mode, but i don't know how.

Any advice, tips, help, is appreciated.

Thank you!

Have you tried, while the external monitor is plugged in, uninstalling the display driver you installed and then installing a new one?

If you can see on the external display you should be able to do that.

OR you could try using "System Restore" to restore the computer to a point prior to the driver change.
