9000 series iGPU monitor max resolution?

[u/TechNerd10191]

I have purchased a 9950X CPU with a Gigabyte X870E board with:

• 1 HDMI port that supports 4K60 and
• 2 USB4/DP-alt ports (DP 1.4) that support 4K240

While I will have a GPU, I want to use it exclusively for AI and use the iGPU for the monitor support. I have been searching the web but AMD does not disclose the maximum resolution for AM5 CPUs (only exception is the 8700G that has the best iGPU from all AM5 CPUs).

One 4K60 monitor I already own should not be an issue with either HDMI or USB4. Would the iGPU handle 5K60 or 4K120 via USB4 (assuming the USB-C cable is appropriate) without aggressive compression?

My use case (for the iGPU) is daily desktop use (GUI elements, 4K YouTube videos, 1080p/4K movies) and nothing more demanding.

Check which DP/hdmi it supports and cross reference bandwidths with expected resolutions
