KVM

3 (three) to 5 (five) second delay.

February 23, 2026 2:49:49 PM from Stardock ForumsStardock Forums

I am trying to use the KVM mode on my Windows Server 2025 DataCenter and upon connection (happens very quickly), every mouse click has about a 3 to 5 second delay.  However I can see on the actual hardware monitor of my server it happens immedialty.  Is there a settine to correct this.  I have disabled the firewall on the Server workstation.  I attempt KVM on other workstations and it works very well on the same network and subnet and it works very well.  The Server is a Dell Poweredge R630 1U Rack Server.  Thanks,

so the issue is the screen updating very very slowly on that machine vs a slow input issue?

First thing to check is what is the network bandwidth available between those two machines?

Ran iPerf3 and got 4.3 Mbps for lan bandwidth.  Tested with RDP to same workstation works great, tested with iDrac using virtual console, works great.  Turned off firewall, turned off defender.  Maybe it doesn't work with Windows Server 2025 Datacenter.  Wish it would.

4.3 Mbps is not that big.  KVM mode is designed for extreme low latency over your local network at the cost of bandwidth usage.

That said we do have something coming soon which may be more suited to your needs.
