Monitors turning off sporadically.

I have the three output plugged into a Lenovo laptop, fully patched for drivers and OS.

I am using the display port and HDMI port and the monitors will turn black sporadically sometimes one, sometimes the other one, and sometimes both.  They will stay off for about 5 to 10 seconds then turn on again.

Hi Jonm,

What hardware (notebook/displays) and docking station from Club 3D do you use?

Please be more specific. With “It does not work”  I can’t assist.

My IT will reply you in about 20 mins he knows more of the hardware to be specific. Thank you and looking forward to fixed this issue.

Hi, thank you for your response.

It is a Lenovo Legion 7 with 32.0 GB

Fully patched Windows 10 Pro

The graphics card is a NVIDIA GeForce RTX 2070 with Max-q Design, running drivers from 2021-06-21

The other card, (I’m not sure if this is the one in the dock somehow?) is a Intel(R) UHD driver from 2020-09-24

The Dock is showing up as a PD3.0 USB-C Device, running MS drivers 2006-06-21

This is the Dock we are using.

So the problem is that One or the other monitors goes black (or both), does not power down, then comes back after about 5 seconds, Do not notice the device noise you get when you insert or remove equipment.

The USB-C cable we are using is 6 feet long.

Intel UHD might refer to the GPU that’s integrated in the CPU (iGPU for short).

Are the displays connected to Nvidia or Intel? See this in the Device Manager, change to View by Connection, then find the displays.

Displays sporadically turning off/on means a bad connection (if you feel that this is not a problem related to sleep – if you are always moving the mouse then it shouldn’t be falling asleep). Therefore try a shorter/different cable – but the dock comes with a short USB-C cable. Are you not using that cable?

Does the problem occur with only one display connected to DisplayPort?

Does the problem occur with only one display connected to HDMI?

A dock doesn’t have drivers. It will have drivers for its component parts. This dock consists of a USB 3.0 hub for the USB ports and built-in USB devices: a USB to Ethernet adapter for the Ethernet port, a USB to SD Card reader for the SD Card slots, a USB Audio device for the audio in/out port, and a DisplayPort 1.2 MST Hub for the display outputs. There may be a driver for the USB hub, a driver for the Ethernet adapter, a driver for the SD Card reader, a driver for the audio port, a driver for any USB devices connected (mouse/keyboard/storage device) and a display driver (Intel or Nvidia) for the MST Hub and any displays connected to the MST Hub. Most of the drivers should be built-in or come from the manufacturer of the individual devices. Connected to the MST Hub is a DisplayPort to VGA adapter and a DisplayPort to HDMI adapter (or they might be built into the hub). I don’t think this is a driver issue. Maybe a driver or firmware update could make it less susceptible to display connection issues by ignoring disconnections that last only a short period of time but probably not.
