So I wanted to reinstall my display driver but when I did I managed to get a really small screen but I figured out to maximize it . But whenever I want to launch games now it says I need to update my Graphics Driver. I have tried updating it with the graphic drivers on my computers support site but they came up with an error: This computer does not meet to minimum requirements. But my friend has the same laptop and it uses Intel HD Graphics 4000, which was my one befire I uninstalled it. Also another problem without this driver is that my brightness keys are not working and I can not adjust the brightness.
