Hi thanoskokos , 

 

Welcome to the Community Forums.

 

Was the brightness worked on Windows 10 before you had the drivers updated?

If so then going back to the device manager , you may do a drivers rollback .

 

Update us how it goes.

Similar discussions here.

Hi thanoskokos , 

 

Greetings. 

 

Do try doing a driver rollback from device manager.

 

While on device manager , on network adapter wifi right click to choose properties. Click on power management tab and uncheck box "allow to turn off to save power" . This would help on the disconnection issue . 

 

For the original display driver issue try this steps (tdr delay set to 9)  :

a. Press the ‘Windows + R’ key on the keyboard.

b. In the ‘Run’ windows type regedit and hit enter.

c. Browse to and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\GraphicsDrivers

d. On the Edit menu, click new, and then select the following registry value from the drop-down menu specific to your version of Windows (32 bit, or 64 bit):

 

For 64 bit Windows:

a. Select QWORD (64-bit) value.

b. Type TdrDelay as the Name and click Enter.

c .Double-click TdrDelay and add 9 for the Value data and click OK.

e. Close the registry editor and then restart your computer for the changes to take effect.

 

Update us how it goes.

 

Regards
