When I connected my laptop to the screen, my screen did not show 100% brightness even though it was set on the screen.
I still see everything on the screen, however, the brightness is on felt 20%.
Does the screen have any defect and if so, can I fix it?
Check if he is in energy saving mode then 100% really only about 50% performance.
If it is not because I would like to see if the battery has something, so pc s.einen cable and battery to remove.
If that does not help, unfortunately, I can't help you because I do not have the device in my hand.
Press the menu button on the monitor and adjust the brightness to the desired height.
