multimonitor Dual Monitor setup issue

[kubilay.buday]

Hello,

I've been trying to setup dual monitor for my pc.

I've got a 2k monitor for gaming etc. and i've got 720p old monitor for discord, whatsapp web etc.

I didn't want to use external gpu for that so i've plugged old monitor to motherboard hdmi. (iGPU enabled in bios, iGPU multi monitor enabled in bios.)

I don't want to use external gpu like desktop windows manager, chrome, explorer.exe etc. So I've chosen iGPU for that programs. But it didn't work out. Everything still using eGPU instead of iGPU.

2nd monitor working properly and plugged into motherboard. I really don't get it how it's even possible. 

Could you help me for that

Best regards

I'm not super familiar with this particular issue, though I do know that once a dedicated GPU is installed the iGPU in desktops is usually disabled, I honestly don't know if it's even possible to use both at the same time for different monitors, and if it's even possible as there is no reason to not just have both monitors plugged into the dedicated GPU. I would honestly just plug the monitor into your dedicated GPU as well, it's not going to affect it's performance just running a 720p secondary display. I think you're trying to jury rig something that doesn't even make a difference. Just plug both monitors into the dedicated GPU and be done with it.

Thats how its supposed to be. Not many you can have actually use it. Only time I noticed it working is watching a video of some kind, but even then it isnt solely done by the igpu.

Which monitor is set as the primary monitor?

There are ways to select specific GPUs for certain tasks. But in this case it's much easier to just plug in the GPU for both of them. From my experience related to this. I hooked two GPUs up to my PC just for the laughs and because I like to experiment. The issue with doing this however was with to many applications using the second GPU it takes away a significant amount of performance away from the CPU. So in trying to make my GPU more available for gaming I shot my CPU in the knee and told it to run. My CPU is a Ryzen 7 3700x too.  Which overkill anyways. But it still brought the overclocked score from 11880 to 10400-10500 in the classroom benchmark. I don't know how heavily the IGPU would do this to your CPU if you tried to use both. But in this case for sure, it's just a 720p monitor if you have a half decent GPU you shouldn't notice the performance drop even when looking at the FPS itself

Actually you might be right for CPU.

My system has; i5 11600K @5Ghz, 3060ti, 16gb ddr4 3600mhz ram. Didn't benchmarked the cpu gonna give it a shot anyway. It's between 2-10 percent usage on desktop for the eGPU. Is it OK though?

I would just run the benchmarks. use more IGUP in one and then use only the gpu. stress test the GPU and CPU at the same time so that way the Igup has to actually used. ETC.
