I'm a complete noob with hardware so can someone please help me.

My GPU can support up to 4 monitors. I have 5. I figured that since you don't need a GPU for a computer to work, my PC would be able to support 4 with my GPU and one with the on-board system, but apparently I am wrong.

Is it possible to configure it to work this way? Will this seriously impact performance? (It shouldn't right? As PCs are designed to run with one monitor)

I know it is possible to connect multiple GPUs so if that's not possible, could anyone give me any advice on that? Thanks!

    I don't belive its possible to use the on board as well as the gpu, but I could be wrong as its been ages since I pulled apart a PC lol

    All depends on the motherboard.


    On most motherboards, it will shit on your perf, CPU will be used to render video for that output if it can be enables simultaneously. There a re a few with a small integrated video processor, but they will steal power from the 12v rail on the main. Also not ideal.

    Just grab a second video adapter 🥳

    @SortOfTested Thanks! Do you have any tips / tutorials for connecting a second one? If so that would be great!

    5 monitors? That's a lot! But you will need a second GPU for it.

    Plug it in to the pci-e port, attach whichever vga power it needs (6/8pin), should detect it as a second device. Good to go

    @LavaTheif You could even use the non-gaming cards for this purpose (e.g. Nvdidia GT instead of GTX, no idea of AMD names), but I have no idea if it will negatively impact the output performance if your first card is better.

    👆This, also.

    @sbiewald thanks! Should it just work with any gpu or should I stick to the same brand?

    It depends on your system.

    At work, we're only using USB-C monitors (one to two LG Ultrawides poer desk) because they can also be used to charge the Dell Notebooks or MacBooks we're using. I got an USB-C to Ethernet, HDMI, VGA and a third USB-A Port adapter with the Notebook and I am currently using that one to connect to my VGA Monitor at home and I've connected a second external screen on the HDMI Port.

    Thus: USB-C might be a solution for you.

    @LavaTheif I would stick to the same "developer" (AMD / Nvidia), but I don't see the need to stick to a single manufacturer (Gigabyte, Asus, ...).

    In theory there shouldn't be any problems when mixing them, but I wouldn't risk it.

    @sbiewald One last quick question, I know that with sli it will limit the ram to 2gb on both if the lower one has 2gb. Is that the same when they're not in sli?

    Edit: actually, that doesn't matter, but I am still kinda curious

    @LavaTheif No, the memory won't be limited, they will act like two completely separate devices.
