Hello again,
I received the 3 new cables as mentioned, and for the moment there is no solution. This is my current scenario: | ASUS N580VD --> USB-C --> DELL D6000 | |--------- Station HDMI Port --> HDMI Cable--> Monitor HDMI Port | |--------- Rankie HDMI ->DisplayPort 4K adapter --> Docking DP Port --> HDMI Cable--> Monitor HDMI Port With this configuration, the 2 attached monitor are not flickering, and the third monitor works attached to the HDMI built-in port of the NoteBook. Adding the third monitor | ASUS N580VD --> USB-C --> DELL D6000 | |--------- Station HDMI Port --> HDMI Cable--> Monitor HDMI Port | |--------- Rankie HDMI ->DisplayPort 4K adapter --> Station DP Port --> HDMI Cable--> Monitor HDMI Port | |--------- Rankie HDMI ->DisplayPort 4K adapter --> Station DP Port --> HDMI Cable--> Monitor HDMI Port The monitor attached to the HDMI port of the docking starts again flickering. So, if at start the problem of bad manufactured cables was one of the cause, it is partially solved. The problem now is using both DisplayPort ports of the station. |

Hi again,
I'm officially out of ideas. I also tried buying DP->HDMI "active" adapter (whatever that means) as suggested by some sites and tried the shortest HDMI cable (0.5m). Always the same behaviour of flickering. At this point the only working solution is using the 2 DP ports of the station and the built-in HDMI port of the notebook. The USB->HDMI graphic adapter seems to work bad, after some point all the monitor goes black and all windows position are resetted to notebook monitor. Any thoughts on this? |

Hello again,
The 3rd output is never using our technology so whether it works and fixing it, is not under my control, unfortunately. The chip we make that Dell uses in the box only has 2 simultaneous outputs possible. When using 2 displays (DPx2, DP+HDMI) it all goes through us because of internal switches, when you add the 3rd display, both DP are connected to our chip, and the HDMI is driven by the laptop through a converter (like your USB-C to HDMI standalone converter you tried, because the laptop outputs DisplayPort Alt-Mode and standard USB, not HDMI Alt-Mode) and that's when it starts the flickering. I don't understand your case of DP->HDMI active adapter. A passive adapter means it's not really DisplayPort, it's HDMI signals disguised in DisplayPort connector (called DisplayPort++ or Dual Mode). An active adapter means the adapter is generating an HDMI signal itself, so it's not driven from the dock or the computer. Kind regards, Alban

Hi AlbanRampon,
at this point I don't know what to think, I'm unable to find a common ground on all my attempts. It seems to be random, at the end I tried: - different notebooks - different stations (2 different brands) - different monitors - differente cables The behaviour is always the same, the HDMI connected monitor is flickering. The only common variable here is that all the notebooks I tried are ASUS branded (I don't have other USB-C notebooks of different brands), but I don't know if this can be a cause of my problem. |

StarTech USB32HDPRO adapter (USB->HDMI) is using DisplayLink technology as well. So, from what I can see, when using any of the DL-3xxx, DL-5xxx, and DL-6xxx HDMI outputs, your monitor works properly. You have issues when using the Alternate Mode, and potentially with DisplayPort converter chip. When all your displays flashed, it could be because of a driver crash. The notebook will blink as you change the desktop layout. If you still have that adapter, I'd recommend plugging it to your docking station and use it to drive the HDMI monitor. Should it crash again, we can look into the crash data to improve the driver. Kind regards, Alban

In both cases after some time both monitors get stuck, after few seconds they became all black and the all the layout is resetted (all windows are moved to the internal notebook monitor). I don't know... maybe the StarTech adapter is damaged, but at this point I'm willing to consider a problem with the Intel driver itself of the notebook, not any external device I can use. |

From first tests with the StarTech USB3DOCKH2DP I just bought, I can say that all 3 external monitors are working fine, even with the notebook display enabled: https://photos.app.goo.gl/s5p6UEZcY5nW5Jnf8
The difference here is that is an older model which use only the USB3.0 port and not like the newer model which uses the USB-C port. From Control Panel of Windows I can see that 3 monitors are managed by the external station (instead of 2+1 like other model) and only the built-in monitor is managed by the internal Intel chipset. Also, just for test purposes, while the dock was connected I attached 2 additional displays on the built-in HDMI port of the notebook and on the built-in USB-C port of the notebook (with a simple adapter), and all 6 monitors are working correctly. And in this case, 3 monitors are managed by the Intel chipset and 3 monitors are managed by the external station. https://photos.app.goo.gl/T3P83vCFZzhnmH3FA After all this tests and this success, I'm willing to consider an USB-C incompatibility problem or something related to the notebook hardware or Windows drivers. I will try a couple of days with this station but for the moment is seems the problem to be finally solved. |

I do have the same problem. The third monitor that connected via HDMI is flicking from time to time and it's really annoying.
I ended up connecting the HDMI directly to my labtop (Dell Inspiron 13 7370) which is shame as I bought D6000 to replace my D3100 just because I want to have a single USB-C connection to my machine |

Now that I tried this USB docking station it seems that the problem is related to the USB-C functionality. Have you tried the previous docking station using a USB->USB-C adapter? |

I thought that upgrading to D6000 would allow me to forget the power line and use only a single USB-C to connect to my machine. Now I can get rid of power line but need HDMI instead However, just a few days ago, Dell has updated the driver and it's less flicking. Hope they'll keep updating until the problem gone. |
