Ok this has to be one of the strangest problems i have ever seen

Ok i just bought laptop recently and booted it up every time i can see bios screens just find on the lcd but when it booted up to the windows setup the screen went black. I connected a external monitor to go through the process and then when i get through with it i finish and i still have no screen. I restart to no avail reinstall drivers reinstall with the dell ctrl f11 nothing works til i try to boot into safe mode then wow my screen works perfectly. I then tried restarting and have done just about everything to get this thing to work. Now i just uninstalled video card drivers and rebooted it and i get picture until i mess with the monitor drivers or restart again. The monitor drivers are all called default monitor and there are four of them. I guess i am going to be sending this back to dell :(
