I am trying to extend my monitors to 3. I can see the three monitors in the Intel Graphics Command Center but I can't get the 3rd monitor to enable. I have yet to find a solution. Intel 630 graphic cards Windows 10 pro

What is the model number of your laptop or system/motherboard?

What version of WIndows 10? 1909?

What is your processor model number?

Have you tried better cables?

It is an I5-8400 processor, Motherboard AsRock H310M-HDV/M2, windows 10 pro 10.0.18363 build 18363. I have one connected hdmi, one vga, and one dvi. All three monitors work I can use any two of them but I can't get the third to extend or enable. I can switch which two I am viewing at any time so I don't believe it is a cable problem. From what I have read the graphics card supports 3 monitors.

Your processor supports three monitors:

How AsRock implement support for monitors on their board is a question you have to ask them.
