That’s not true. Usually integrated graphics are disabled when gpu plugged in but it’s also usually possible to re enable it in bios.

If all the video outputs on my GPU were in use, could I use the motherboard video outputs and integrated graphics to connect more monitors?

 

I think the answer is yes for Ryzen 7000 series chips with integrated graphics, but I can't find anything online specifically confirming this.

Common build advice: 1) Buy the cheapest (well reviewed) motherboard that has the features you need. Paying more typically only gets you features you won’t use. 2) only get as much RAM as you need, getting more won’t (typically) make your PC faster. 3) While I recommend getting an NVMe drive, you don’t need to splurge for an expensive drive with DRam cache, DRamless drives are fine for gamers. 4) paying for looks is fine, just don’t break the bank. 5) Tower coolers are usually good enough, unless you go top tier Intel or plan on OCing. 6) OCing is a dead meme, you probably shouldn’t bother. 7) "Bottlenecks" rarely matter and "Future-proofing" is a myth. 8) AIOs don't noticably improve performance past 240mm.

Really no reason why you couldn't. The iGPU in Ryzen 7000 is a fully capable display adapter, even have support for 4 4k displays.

The iGPU in a lot of OEM systems gets disabled when it detects a dGPU, but in general, there's no reason why you couldn't use the iGPU of a system and all the available display outputs from every PCIe slot filled with dGPUs.

 

There's a maximum vertical and horizontal resolution possible in Windows itself at 32,000 x 32,000 pixels but with a maximum of 128M pixels. So, if you were able to have enough display adapters to occupy all of those pixels, then you could stripe a bunch of displays together to get anywhere from 32,000 x 4,000 or 11,313 x 11,313 and anywhere in between those not to exceed 128M pixels.

Yep, I do just this. My secondary displays are driven from the iGPU on my 7800x3D.

Thanks all for the confirmation, you've been a great help 🙂

Just know though issues could arise when dragging videos across the igpu and pcie card. This has been an issue with drivers and multiple video cards for a long time now. You could get crashes. When you keep the window dragging to one card, no issue but dragging videos and windows across multiple cards in your system can induce errors. Just fyi something to look out for.

Year and a half with Nvidia dGPU and the AMD iGPU side by side, its been flawless. 

 

All sorts of things "could" happen but this isn't a common concern.
