ok you can check to see If u have multiples of the same monitor device. Keep in mind that you are supposed to have two of the same monitor in Hidden devices. One is for when you uninstall your video card driver. The second is for when you do install your video card drivers.
open command prmpt with Admin. privileges
type: SET DEVMGR_SHOW_NONPRESENT_DEVICES=1
Next, type devmgmt.msc and hit Enter to open the Device Manager.
From the View tab, select Show hidden devices. You will see some additional devices get listed goto Monitor.
Delete all but 2 of the same monitor. Only delete the grayed out ones.. Just save 1 grayed out monitor of the same type and one active monitor of the same type.
