Trouble Shooting Common Issues with Deskwall

Issue 1: Keyboard and Mouse Lag or Stuttering Across Windows

Symptom: The cursor stutters or delays when moving from one server feed window to another.

  • The Cause: Network latency or temporary packet dropping between the DeskWall processing node and your local KVM network switch.
  • The Fix:
    1. Inspect the Ethernet activity indicators on the back of your local DeskWall receiver module; ensure a solid green link light is present.
    2. Avoid connecting your DeskWall processing nodes to standard office Wi-Fi networks or unmanaged daisy-chained network hubs. Ensure it is patched into a dedicated corporate gigabit switch port.

Issue 2: Connected Source Window is Completely Black

Symptom: A layout grid sector displays "No Signal" or stays entirely black while the source computer is known to be powered on.

  • The Cause: An HDCP handshake error, a mismatched display scaling resolution, or an inactive video graphics driver sleep cycle on the target machine.
  • The Fix:
    1. Bring up the DeskWall Admin Widget and click Refresh Source Input.
    2. Verify that the host computer's display output resolution is explicitly locked to $1920 \times 1080$ at 60Hz or $3840 \times 2160$ depending on your specific hardware baseline. Interlaced resolutions (like 1080i) are not supported.
    3. Ensure the physical video patch cable (DisplayPort or HDMI) connecting the host source machine to the local DeskWall transmitter unit is secured tightly.

Issue 3: "Follow Me" Control Disappears at Screen Edges

Symptom: Your mouse hits a virtual wall at the border of a window partition and refuses to transition over to control the neighboring screen feed.

  • The Cause: A layout grid configuration mismatch or the local screen coordinate alignment has gone out of synchronization.
  • The Fix:
    1. Open the DeskWall menu widget and reload your current default layout preset to force-realign the coordinate mapping grid.
    2. If the cursor remains trapped, press your emergency unlock sequence (Scroll Lock twice or Ctrl + Alt + K) to cleanly break the KVM loop and reset the cursor position back to the primary desk workspace.
