Tesmart DKS403-M24 and Nvidia 4080 - randomly video when switching back to it

Ive bought this KVM because of the 144Hz support and the 3 monitors it can switch.
One thing I have not figured out yet is why in random cases, there is absolutely none of the screens working when switching to my workstation with the Nvidia 4080 card on win 11. I have to power cycle the KVM to get a signal again. No problem on my mac or other devices.

Is there any trick to it ? Does that happen with other KVMs as well ?

Issues with solidworks and KVM GPU Passthrough

So, I have enabled GPU passthrough, following this guide: https://doc.opensuse.org/documentation/leap/virtualization/html/book-virtualization/app-gpu-passthru.html

When I run my windows 11 guest, it recognizes my GPU as a Nvidia Quadro P2000. When I run the passmark performance test, it will also find my gpu.

However, when I run the Solidworks RX 2026 software, it says it is a GDI Generic, with the current driver R580. Is there still some setting I am still missing? Why does it not recognize my gpu? I still cannot run hardware accelerated graphics with Solidworks 2026 maker edition.
