I've a problem in the last few weeks is that windows detects a second monitor named Generic non-pnp monitor. It had it from long time but I selected my real display as the main one and I had no issue with it, but in the last 2 weeks it sometimes keeps detecting that I installing and removing it continuously and make that sound you hear when you plug and unplug a usb device and it also cause a little freeze to my pc and stuttering.I've tried to install a fresh windows and to uninstall my GPU driver completely and installing the newest one and then go back to 19.9.2 driver, I also tied another display, cable and HDMI port of the GPU but nothing changed and hope you can help me.
my PC specifications:
CPU:AMD Ryzen 5 1600AF stock
MOTHERBOARD: ASROCK B450M-Steal legend
GPU 1: ASUS ROG Strix RX 480 8gb stock
RAM: XPG Gammix D10 8gb 3200 DDR4
PSU: seasonic s12ii 520w 80+ bronze
I tried your method and I tried display driver uninstaller before and the same problem always there.
before installing the driver everything is fine, just after installing it that ghost monitor pops up.
I'm using the latest driver right now
+ Download DDU and run it.
+ Disable Windows driver update and enable safe mode (removing vulkan and monitors driver) in the settings of the DDU, and re-run the program again.
+ Uninstall old drivers using safe mode by choosing DDU option.
+ Delete C:\AMD and C:\Windows\SoftwareDistribution\Download folders.
+ And install the latest display driver.
If you are seeing the nonexistent monitor again despite all these attempts, you can try reinstalling Windows with an USB stick.
I did exactly as you said and still the same problem
I had this problem with my previous windows then I downloaded a new windows 10 iso from windows creation tool and installed it so this is a fresh one. any other ideas?
and thank you for your help
Do not install chipset driver. Just try a clean Win10 installation and display driver installation. I don't know why the problem is happening. Maybe the chipset driver...
