OS Windows 7 x64 10GB RAM
Video card RX 550 4GB
Monitor HDMI LG Ultrawide 25" 2560*1080
The video card thinks that there is a monitor on the DisplayPort, but I never used this output, and there are no settings to this ghost monitor, one month now with this video card and I can't even play games, because it keeps making a sound of a disconnected usb device, the screen blinks, the computer hang for some seconds, and then a sound of a usb being connected, the screen stop blinking and a ghost monitor appears on the monitor settings.
Even if I uninstall this ghost monitor in Device Management, it comes back after 3-5 minutes, making that annoying sound of usb, blinking the screen and locking the pc.
Making the video setup to only show the desktop in the monitor 2 (my only monitor is shown as 2) I can use internet, hearing the annoying sound of usb all the times that this ghost appears, but I cannot play games.
If I uninstall the graphic card drivers, it stops to appear and disappear the ghost monitor, but without these drivers the pc is slow.
Is there a way to delete only the driver of the DispayPort?
Is there a way to disconnect forever the DisplayPort output?
