I'm using a CMSTEDCD SW523P KVM switch to connect two monitors through DisplayPort: an Asus VG248 (144 Hz) and an Asus PA248 (60 Hz) with my Dell Precision 5570 via USB-C. I'm experiencing two main problems: first, both monitors occasionally go black for a couple of seconds during use, and second, the 60 Hz monitor sometimes displays odd artifacts, such as the taskbar shifting and duplicating. I've tried switching inputs on the KVM to fix the latter issue temporarily. Screenshots don't capture these problems, so I suspect it's a hardware issue with either the KVM switch, monitors, or cables. I've already tested different DisplayPort cables, but the issues persist. Can anyone provide insights on the cause or suggest a better KVM switch for my setup?

The problems you're facing are likely due to the KVM switch lacking proper EDID video emulation, which can cause the blackouts and artifacts. I recommend investing in a higher-end DDM-class KVM switch, and make sure to use quality video cables for the best performance.
It sounds like a connection issue, possibly with the KVM or the cables you’re using. Confirm you're connecting through a Thunderbolt port on your Dell with a certified Thunderbolt 4.0 cable. That might help stabilize the connection. Do you have a link to the switch specs? It could provide more clues.
