AMD AM4 mainboards with three digital display outputs

Suppose you want to build a low-cost triple-screen desktop PC but you aren’t a hardcore gamer and don’t want to spend hundreds on a discrete GPU. Luckily, there are several mainboards with built-in video connectors that can be used with the latest generation of AMD APUs that combine an excellent CPU with a decent integrated GPU.

For this list, only mainboards that can display distinct content on 3 monitors simultaneously via DisplayPort, HDMI, USB-C, or DVI. No VGA, monitor mirroring, DisplayLink, or MST hubs allowed.

AMD AM4 mainboards with triple digital video output

For budget compact builds, my pick would be the Gigabyte A520I AC since it comes with wi-fi and has plenty of expansion options including 1 M.2 SSD slot and 1 PCIe x16 slot.

For a mid-sized build, the Asus Pro B550M-C/CSM offers more expandability with 2 M.2 SSD slots, 1 M.2 wi-fi slot, 1 PCIe x16 slot, 1 PCIe x4 slot, and 1 legacy PCI slot.

Match either of these boards with an AMD Ryzen 5 5600G or Ryzen 7 5700G processor with built-in Radeon graphics and a dual channel 16GB CL16 3200MHz DDR4 ram kit, and you’ve got the basics of an excellent PC workstation.

The less expensive Gigabyte A520M mainboards are OK for running 3x 1080p or 2x 4K60 but won’t be able to run 3x 4K60 or even 3x 1440p as the DVI port is limited to 1920×1200. So if you’re serious about screen real-estate, I’d skip them. The Thunderbolt-enabled mainboards technically meet the requirements, but they do not offer good value for this type of build and are better suited for Ryzen 5900X/5950X processors and discrete PCIe GPUs.

If you’re planning a build based on an AMD APU, let me know which mainboard you end up choosing and why. I’m fascinated by how many different models there are and how unique everyone’s perspective is on which features are important.
