Windows 10: Windows 11 with dual RX580 GPU installed , secondary GPU's monitors not detected

Hi, I have two RX580 installed, worked like a charm in Win10 with no patches. I've just upgraded from Win10 to Win11, monitors connected to the secondary GPU do not work.I've tried to run SFC, reinstall drivers, reconnect monitors, change graphic settings - nothing works. At the same time I can see both cards in Device Manager and in AMD Radeon Software, so I believe this problem is not driver-related and definitely not hardware-related have secondary OS installed on the same PC - still no issues there. Noticed that there are quite strange Graphics options: What's the point of power saving/h

GPU not detected

Hello,

I have been slowly rebuilding my old desktop. Some of the parts are old, but I have currently upgraded the RAM, mobo, CPU and hard drive. I would like to try and keep it where it is at instead of spending more money on it. I am experiencing an issue with
detecting the graphics card. I have a monitor hooked up to the graphics card and, obviously, I can see what is going on. So I know that the GPU is being detected, but when I got to device manager, I cannot find the GPU anywhere. I have also typed in the
command

into command prompt and it also says that the only video card I am using is the Windows Basic Display Adapter. I have checked online and the GPU is compatible with the motherboard so I know that isn't an issue. For reference the GPU is a GTX 560 Ti. I
know it is a bit older, but I don't really need to update for the games I play. I just need it to work. Are there any other suggestions as to what I should do? I have listed my current build below.

OS: Windows 10 home edition 64 bit

Mobo: ASROCK x370 Gaming k4

RAM: EVGA DDR4 16GB

CPU: AMD Ryzen 5 1600x Six Core Processor

Again, any suggestions on how to solve this so my GPU is detected would be greatly appreciated! Thank you very much and have a great day!

GPU is fine.... Bios is fine.... Why can't Windows 10 detect my second monitor?

Now my second monitor isn't even cloned... no signal... windows 10 cannot detect a second monitor and suggests a different GPU... My GPU can support up to 3 monitors... again... ran every diagnostic on my BIOS and GPU know to man. Thank you for your assistance...
very irritated by this simple problem.

 

Second monitor streamed using Elgato HD60 Pro not detected

Hi,

Thank you for writing to Microsoft Community forum.

• How is the setup done? Do you mean to say that the monitor streamed is not being detected?
  

Standard graphic cards that do not have the special DMS port will not be able to send out two separate display signals to two different
monitors. Seems like the monitor is attached to the onboard GPU port instead of NVidia, if the display is not being detected despite of the GPU supporting dual monitors. You may plug the
monitor into the NVidia GPU port and check if it’s being detected.

If the issue persists, it could be due to faulty drivers. I suggest you to install the latest drivers from
NVidia.

Regards,
