My Display Adapter couldn't be installed normally on my computer, what to do? Following this article, I will show you my way to troubleshoot my Display Adapter driver installation issues. Then, I went to the Computer Management to check for my Display Adapter, I found there is an exclamation (!) symbol on it. I went to the display settings to change the settings to normal, but the next day when I open my Windows again, the screen displays in the abnormal way again. When I started my Windows 7 PC, the icon and text on desktop were so big that was not displayed well. A few days ago, there was something wrong with my display screen.
