How to fix your DisplayLink product from repeatedly disconnecting and reconnecting, or freezing

You might meet the following issues with HD00006 / HD00009

■ Repeatedly hear the device disconnect and reconnect chime
■ 2nd Monitor repeatedly flashes off and on again
■ Or HD00006 / HD00009 freezes or locks up, while directly connected screens, eg the built in laptop screen, continue to work.

This can be caused by loose video cables or USB instability. Firstly check that the video cable is fully plugged into the dock and the monitor. If it is loose, the monitor will be detected and then lost by the dock, causing display reconfiguration. If this does not solve the issue, follow the steps below:

1. Check the latest DisplayLink software installed

You can locate the latest version on our Driver Downloads

2. Check the latest USB 3.0 host controller driver installed
3. Check the latest BIOS version installed on your PC

Visit your PC manufacturer's website to see if there is a BIOS update available for your computer. Also check if USB 3.0 mode (if present) is enabled in your BIOS

4. Check if the same behavior is seen when connected to a USB 2.0 port on your PC (or if none is available with a USB 2.0 cable)

Some USB 3.0 enabled PCs can exhibit issues on USB 3.0 ports but not on USB 2.0 ports

5. Check if the same behavior is observed with a different USB cable or USB port

As with other kinds of cable, USB cable quality can vary. We have also been made aware of rare quality issues with selected USB ports on a laptop series.

6. Try a USB 'Y' cable (if you are using a USB powered monitor product)
Try connecting your product through an external mains powered USB hub

Ensure you connect both ends of the 'Y' cable to USB ports on your PC

7. Try connecting your product through an external mains powered USB hub

Some USB 3.0 enabled PCs can exhibit issues which can be resolved by connecting your product through an external mains powered USB hub

8. Disable USB selective suspend

1. Open the Control Panel on your PC
2. Select Hardware and Sound
3. Select Power Options
4. Select Change plan settings against your preferred power plan
5. Select Change advanced power settings
6. In the Power Options dialog that opens select USB settings
7. Select the USB selective suspend setting
8. Change the Setting to Disabled

9. Check for error codes in Device Manager

ERROR CODE 43

This is usually due to a driver fault. To fix this error we recommend trying the following steps:

• Unplug your DisplayLink device and restart you laptop
• If the error still shows when you plug the device back, try updating the driver. 
• We also recommend running a DisplayLink Installation Cleaner first
• Update the computer's BIOS/UEFI with the appropriate file from your system/motherboard manufacturer.

ERROR CODE 10

This has been either due to a faulty device, or due to a device with auto install (which are not supported as detailed below) and the DisplayLink video driver is trying to talk to the wrong interface putting it into an error state.

10. Check PCIe Active State Power Management (ASPM) settings

There have been some compatibility problems reported between various USB devices and some modern, Thunderbolt equipped platforms due to the ASPM settings. We recommend trying disabling ASPM.

TO DISABLE PCIe ASPM

1. Open Control Panel,
2. Search for Power Options,
3. Choose "Change plan settings" and then "Change advanced power settings",
4. In Power Options window scroll down and expand PCI Express,
5. Expand Link State Power Management,
6. Under Settings On battery and Plugged in,
7. Open the drop down menu,
8. Select Off,
9. Click on OK.

IF THE SETTING DOESN'T SHOW

Run this command that will change the settings via Registry change.

TO REENABLE PCIe ASPM

1. Under Settings On battery and Plugged in,
2. Open the drop down menu,
3. Select either Moderate power savings or Maximum power savings (difference explained below),
4. Click on OK.

There are two levels of power management in the PCIe options. The difference between them are the power savings versus the latency (time to recover from the sleep state).

• If you select Off, there are no power savings, and the current will run regardless of what state the laptop is in. (depending on if your laptop is plugged in or not).

On battery: Off = PCI Express will communicate even when using battery power.

Plugged in: Off = PCI Express will communicate when plugged in as well.

• If you select Moderate Power Savings, the power savings are less, but the time to recover from the Sleep state (latency) is much shorter.
• If you select Maximum Power Savings, the power savings are greater, but the time to recover from the Sleep state (latency) is much longer.

FOR IT MANAGERS

You can disable PCIe ASPM for all of your users using the steps above or by running the command below:

Press Win+R, and type in

powercfg /setacvalueindex SCHEME_CURRENT 501a4d13-42af-4429-9fd1-a8218c268e20 ee12f906-d277-404b-b6da-e5fa1a576df5 0
