[SOLVED] How do I run both integrated APU and a GFX card together?

[ChristopherB78]

I have an ASRock Phantom Gaming 4 X570 with a Ryzen 5 3400g running 2 monitors. I recently put in a Radeon HD 7000 series gfx card to try to run a 3rd monitor, but am having trouble getting it to run simultaneously with the integrated gfx. Any suggestions?

Normally you are not able to run the Integrated GPU (iGPU) and the dedicated GPU at the same time. Why would you want to run the monitors on separate cards anyway? It would be best to run all the monitors from the GPU itself, and avoid the iGPU.

I also just realized that you put in a 7000 series, which are quite old. What do you use this PC for? Why such an old piece of hardware?

Typically, if it is possible, there is a setting in BIOS/UEFI that allows you to run both, simultaneously. Reading through your motherboard manual, I did not see such a setting, so it may be likely as @ttower2020 states and that you cannot run both on that motherboard.

Specifically, which HD 7000 series card do you have (make and model number)? It may be possible to run all three displays from the card.

My iGPU is substantially better than the Radeon card that I put in. I honestly just wanted to run the gfx card to my TV so that I could watch movies and stream stuff without giving up the Hdmi ports on my mobo. I stream football games, TV, etc while I'm playing games on the other two monitors. Was just hoping that putting in a card would let me run a 3rd monitor, but I'm starting to think I can't.

Looks like you would need to purchase a new card that supports at least three displays.

All of Intel's i-series that have an IGP are perfectly fine running IGP+GPU concurrently, only need a motherboard that has the option to keep it enabled, I'd expect things to be the same on Ryzen. As for why use the IGP, The 3200G's IGP would be better than HD7000 era graphics, so it makes sense to use the GPU only for extra outputs.

I'm using the IGP on my i5-11400 to run Chrome and Firefox. It prevents them from hogging my GTX1050's VRAM and causing tons of glitches in games.

Interesting that you guys are saying that it is possible to run both the iGPU and dedicated GPU together. In my personal experience, it has never worked when I (or a friend) have tried in the past. I first tried on my AMD FX series, which could explain that, but two friends with Intel systems were never able to get that working properly. Doesnt mean its not possible at all, just odd.

Depends on what you are attempting to do with it. Back then, AMD was trying to do IGP+GPU crossfire, that never worked particularly well.

What I'm doing on my i5-11400 (and discovered I could also do with my i5-3470 while I was in the process of moving all of the hardware I wanted to reuse over) is having the IGP enabled so I can tell Windows to steer applications towards the IGP to stop them from clogging VRAM using Windows' "Graphics settings" config page. There were some driver stability issues until a few months ago which caused Nvidia's drivers to reload (at least for me) but things appear to be pretty stable now.

Not exactly surprised my old i5 could run its IGP concurrently with a GPU. Back in the Sandy/Ivy Bridge days, one of Intel's IGP selling points was QuickSync to alleviate live recording and streaming bottlenecks.
