Dual monitors error message "Didn't detect another display"

Some motherboards have hybrid Crossfire, which will let you run both at the same time. You won't know if yours supports it until you install the correct drivers. If it doesn't, you move the video cable from the motherboard connector to a free one on the dedicated video card. Depending on what connectors are there, you nay have to switch cables or use an adapter. My GT 640 has two DVI and one HDMI. My 3 monitors are all DVI so I use a HDMI to DVI adapter on one monitor.

My computer only has HDMI outputs - no DVI or VGA:s. I don't suppose using an adapter would make much of a difference in this case.

Are there two separate groups of video connectors n the back? It may not have a built in GPU, not all motherboards have them. Two display adapters listed in Device manager implies it does though?

The only video connectors are the HDMI outputs, which are spaced about a quarter inch vertically, so not sure if you would consider this two separate groups?

Is this link showing the PC you have? https://www.advice.co.th/product/des...l-n4r92aa-akl-

If so it looks like it is on board graphics rather than a separate plug in card. You do need the proper driver for the AMD Radeon R5.

I have the 152L, but the back looks identical. What is the proper driver, since the one I have is supposedly up to date? And once I have the proper driver, how do I switch to the AMD since it currently seems to be running on the Microsoft Basic Display Adapter? Or am I missing something?

You need to install the latest Catalyst Driver for AMD Radeon which you will find on the AMD website. Once loaded W10 will then automatically use it.

It didn't work at first, and so then in pure desperation I downloaded a bunch of things from HP Support Assistant and took a nap, and lo and behold, when I woke up, I had an extended screen. Right now I don't even want to make any changes, but one new thing that downloaded is "AMD Gaming Evolved," which I suspect is somehow involved.

Damn it. Display #2 stopped working today. This time, it is not picking up a signal at all. Strange thing is, instead of the Microsoft Basic Display Adapter, I am now seeing Intel(R) HD Graphics 530 under "Display adapters." When the second monitor started working earlier this week, I don't remember checking and am thus unsure whether this changed before or after monitor #2 stopped working.
I now have an Intel HD Graphics Control Panel, and the menu has a "Multiple Displays" alternative, but when I click on it, the only option given is "Single Display" with a supremely annoying check mark to the left, as though I have any choice.
If anyone has a clue what is going on, please share.
