Thin Client has a Black or Blank Monitor on Boot

Possible Causes 

1. If the thin client has two monitors, they may be using a video splitter dongle.
2. The monitor does not have power.
3. The HDMI cable is loose or does not detect the thin client.
4. The thin client does not have power.

Examples of Video Splitters

Solutions 

If the store is using two monitors from one thin clients, they use a video splitter to split the video display. Power surges or other power issues can cause the thin client or splitter to no longer detect that a monitor is attached.

1. Unplug the monitor cable from the video splitter.
2. Plug only one monitor cable into the thin client. Ensure the cable from the back of the monitor goes directly to the back of the thin client.
3. Reboot the thin client and log back in.
4. Disconnect the monitor and reconnect the video splitter.

If the monitor doesn’t display a video image while being the only monitor plugged into the thin client, swap the thin client with another, known-working thin client.

1. Unplug the non-working thin client from the keyboard, mouse, power, Ethernet cable, and any other cables.
2. Move the non-working thin client to a shop bay with a known-working thin client.
3. Unplug the working thin client and plug in the non-working thin client in the known-working shop bay.
4. Plug the known-working thin client and plug it into the non-working shop bay.
5. Power on both thin clients.
6. Does the issue follow the thin client or stay isolated in the non-working bay location?
   1. If the issue persists in the non-working shop bay, something is incorrect with the network cable, monitor cable(s), adapters, or power.
   2. If the issue follows the thin client, it may need to be replaced. Contact ISI Support for further troubleshooting and recommendations.
