Just got the L1T DP Repeater for use with the DP 1.2 KVM. I have an issue where usage with RHEL 8.3 causes persistent screen flickering (persists through reboots, persists through change of OS to Windows). Could be a monitor issue.
GPU: iGPU on Intel 10400 (UHD 630? Something like that)
DP Cables: All L1T DP cables (GPU -> Repeater -> KVM -> Monitor)
Monitor: LG 27in 83A model
