Windows 10: Brightness settings useless, screen dark with a black band, how do I fix this?

I am ashamed to admit that I was desperate enough to believe in an advertised scheme for one of the driver updaters while looking for a solution to an issue I have involving connecting to the primary DNS server (this may be another question in the future). I updated my drivers through it (Tweakbit) and restarted my computer. Now my screen is incredibly dark with a darker vertical band just off centered on my screen. I his the brightness buttons, and no matter what the screen does not change. I even lowered the brightness settings, and there was no darkening - it is as if there is an overlay I cannot get rid of.


I have uninstalled the offending software. What further steps should I take to fix this and maybe undo the damage I may have caused?

Black Screen after Log on

Laptop or Desktop (Very important) Windows 10 build 14.586 has a very annoying BUG: That causes Black Screen after login:
To date there is no cure until Microsoft send Update to fix the problem: OK here goes: When you Login and the Screen Goes Black ==>
Go to your Function Keys for Screen Brightness Chose to Lighten the Screen (This will make the screen Bright) so that you can view it.
The BUG is that they reversed (via Software) what the Brightness button does -- So it is currently reversed -- "Lighten" makes it Dark -- "Darken" makes it Bright ==> Go figure Microsoft screw the pooch on this one. . . .

This is for LAPTOP -- I have never seen this on Desktops but they are fixed rather than adjustable

 

screen brightness on windows 10

Hi,

Some computers can let Windows automatically adjust screen brightness based on the current lighting conditions.

To manually adjust the screen brightness, we suggest following these troubleshooting steps:

• Click Start, then select Settings.
• Choose System, then select Display.
• Under Brightness and color, move the Change brightness slider to adjust the brightness.

Feel free to post back if you have other concern.
