All screens go blank once USB-DVI plugged in
Add me to the list of High Sierra users with the same or similar problem.Before High Sierra all was fine for a year or two with 4 screens counting the DVI-USB one. Now problems since I began running High Sierra on 21.5 inch iMac. Before High Sierra and I had 4 screens working. In addition to the USB3-DVI screen, the other 3 working screens were the built-in iMac had one connected by HDMI from my Thunderbolt extender and another screen connected by Thunderbolt from the iMac itself. I was able to install newest 4.0.0 extension (85514) without security problem. When the USB-DVI adapter is plugged in all 4 screens are blank, and when I unplug the adapter, then the other 3 screens are working again.

For 2 years I have run 2 DisplayLink adaptors each driving a display without major issues while connected to a 27" iMac 5k. The machine is also connected to two external displays driven directly by the iMac. After updating to 10.13, evening running the latest driver, the machine is experiencing similar issues. If I connect either of the two adaptors I regularly use, the iMac's built-in display and the additional two displays being driven by DisplayPort from the built-in ThunderBolt ports immediately blank. As soon as zero adaptors are connected, the built-in display and Display Port driven displays come back to life, but are at the login screen. If I log in and plug either device back into any USB port, immediate blank screens and back to the login screen once disconnecting the device.[/QUOTE] |
I also have the exact same problem.
I have been running 4 external screens and my macbook pro late 2016 internal screen without issue and am using two displayport screens and two displaylink adapters. Everything is connected through a belkin thunderbolt 3 dock. Now I updated to high sierra 10.13.1, and when I plug in all the display link adapters all screens go black. However. If I plug in my two 4k 60p displayport screens and no displaylink screens, then it works as it should. Also if I only plug in the displaylink screens, but not the displayport screens it also works as it should. It seems to be the combination of two external displayport screens together with two displaylink screens. No matter if its though the belkin dock or usb c adapters.

Edit: Extra info If I run two displayport monitors and connect 1 displaylink monitor all screens also go black. If I run two display link monitors and 1 displayport monitor I get this situation where one displaylink is kind of ok, the other not ok, displayport screen and the internal screen black. Mouse can be moved. |

Many Thanks for the hints about mirroring! This was the last piece of the puzzle in order to get my DisplayLink adapter working once again after I upgraded to High-Sierra. Howard |

Hi,
I just bought a Ugreen USB 2.0 to VGA adapter for my iMac 27 2010 running on High Sierra. I have installed DisplayLink Installer 85514.dmg drivers but the display is broken into the finder, please have a look at this screenshot : https://img4.hostingpics.net/pics/78...laylinkbug.png Thanks a lot for your help, have a nice day. |

Unfortunately this issue is expected on any systems not supporting Metal. This is due to a limitation in macOS. Metal-compatible systems use the new Window Server that avoids this issue. Carlo |
Hi Carlo,
Thanks for your reply, so this is a software bug that I will encounter with all adapter using the displaylink chipset ? |
Quote:
So for those of us with Mac's without Metal or Metal 2 support our USB DisplayLink Adapters will see some display artifacts, correct? Do any impair the functionality of the display/cause panics or are they for the most part cosmetic in nature? |

I hope you'll appreciate the effort of transparency here: I'm not aware of any other product suffering from the same issues coming clean about these compatibility problems. Eh. Regards Carlo |
@Carlo
Hi! Any news on why screens go black when using display port screens together with displaylink screens? Its super frustrating to be back on only two external screens after the upgrade to High Sierra. |
