My Dual-Screen 3 shows Xebec Logo then "No Signal" or Black ScreenUpdated 8 days ago

If your Dual-Screen 3 screen shows the "Xebec" logo and then goes to "No Signal," or just a Black Screen with no logo, this is usually caused by a simple connection issue.

Please work through the steps below one at a time, moving to the next step only if the issue continues.

Step 1: Make sure the USB-C cable is fully plugged in

Even a slightly loose cable can stop the video signal. Check both ends of the Dual-Screen 3 USB-C to USB-C cable:

• Push one end of the cable firmly into the Dual-Screen 3.
• Push the other end firmly into your laptop.

Try unplugging the cable, waiting 5 seconds, and re-connecting it once.

Step 2: Try another USB-C port on your laptop

Some laptops only send video through specific USB-C ports.

To send video to the Dual-Screen 3, your laptop's USB-C port must support one of the following:

• DisplayPort (DP)
• Thunderbolt 3 or Thunderbolt 4 (lightning bolt symbol)

If you do not see any of these symbols next to your USB-C port, that port is likely power-only, and you'll need a mini HDMI to HDMI cable for video — just reach out to us to request one. You can also check your laptop's full specifications by following the steps listed here.

Step 3: If you are using a mini HDMI to HDMI cable (skip this step if you are not using this cable)

Make sure:

• The mini HDMI end is fully and firmly connected to the Dual-Screen 3.
• The HDMI end is fully and firmly connected to your laptop's HDMI port.
• Try unplugging the cable, waiting 5 seconds, and reconnecting it once.

Not sure whether you need the cable? Check out our guide here or reach out to us here.
