Hi all!

I am trying to get video output to my main monitor from my GTX 1050 ti and output for a secondary monitor from my motherboard. When I select PCIe as my primary graphics adapter, I my primary monitor (and graphics card) work. When I select onboard, only the secondary monitor works. So both of them work, but I can't get them to display together.

I have the IGPU Multi-Monitor setting enabled. According to various souces on TH and the ASRock forum, this in combination with setting the primary graphics adapter to onboard should do the trick. Only it doesn't.

I should mention that some sources mentioned a BIOS item "onboard enabled" or "onboard always on." I don't seem to have that.

Any help with this would be greatly appreciated!

It is possible that your on-board (I'm assuming "on-CPU") video doesn't have enough RAM to drive both monitors.
A way to test this is... just swap the monitor cables to the other connector. See if that monitor works.

Thanks, but I am already using the appropriate settings (and have played with a bunch of alternatives).

Well, the other monitor is plugged into a 4 GB graphics card, so it just has to power one small monitor.
