AB350 Gaming-ITX/ac 4K output

[spdfreak]

I'm building several ITX cube systems (2400G APU) to display video surveillance cameras on 4K monitors. I want to use both of the HDMI ports- each to a 4K monitor. ASRock says both ports will do 4K but I'm having a hard time getting them to answer if both ports will do 4K at the same time. Does anyone have any experience with 4K and this chipset?

I RMA'd my AB350 Gaming-ITX/ac and replaced it with a Gigabyte GA-AB350N-Gaming WIFI for my 2200G build. I don't have two 4K monitors, but I did successfully test 4K+1080p. Screenshots here: https://forums.anandtech.com/threads/build-with-ryzen-2400g-problem.2538548/#post-39351818

Given you're building multiple of these for video systems, I'm going to assume they're for business use. I'd highly recommend going with the Gigabyte board over the Asrock. They've had far too many issues with Raven Ridge for me to recommend them for that specific use case. @VirtualLarry did you end up testing dual 4K on yours?

Yes, for business use. I usually use Gigabyte boards but I didn't see an AMD Gigabyte board with 2 HDMI outs. I'll re-check. I'd use Intel but I need the 6 core/12 thread capability since the video software basically uses 1 core/thread per camera and if we tile 8 or 12 cameras on a monitor, it takes some horsepower.

The Gigabyte board is 1 HDMI, 1 Display Port but you could get DP to HDMI adapters if your monitors don't have DP. However, for the record, the 2400G is 4C/8T, not 6C/12T.

Yep, I was confusing it with the i7 8700. I may just go with the i7. The Gigabyte ITX board has dual HDMI and dual Intel ethernet. Pretty nice board.

I don't have any AM4 boards with dual HDMI that I know of.

I've got an Asus X470 Prime PRO that has HDMI and DP, but given the physical location of my two 4K UHD screens, I'd need a "long-ish" HDMI cable, maybe 15-20ft.

$11 for 20ft from cablebuilders on ebay..

I ended up building i7 systems with the Gigabyte B360N ITX boards. Really nice boards with dual HDMI and dual LAN. Supposedly dual 4K and up to 1GB shared vid memory. It will probably be a couple weeks until all the cameras are installed and the 4K monitors are in but I'll post results...
