Some users updating to 10.15 have found their DisplayLink devices have stopped working. 5.2 software is designed to run on Mac OS 10.15, but the OS can disable our kernel extension during the update. Please check the kernel extension is enabled and screen recording is also enabled, to ensure DisplayLink enabled devices continue to work when migrating to 10.15.

Displaylink Usb Graphics Software Mac
Since macOS High Sierra 10.13, the operating system applies a stricter security policy to software that requires kernel extensions (KEXTs). The DisplayLink classic driver installation (version 5.x) includes a system extension (DisplayLinkDriver.kext) that is affected by this policy. The new DisplayLink Manager Graphics Connectivity app (version 1.x) does not use KEXT. This article does not apply if you are using DisplayLink Manager 1.x and macOS Catalina (10.x), Big Sur (11.x) and Monterey (12.x)
If you are using the classic DisplayLink USB Graphics Software for macOS (version 5.x), you have to explicitly enable this system extension in the Security & Privacy system preference after installation before DisplayLink software is allowed to run.
Follow Figure 3 - Figure 5 to enable the DisplayLink Software to run on the system. Please note that the interface presented may be different if multiple software require user authorisation.Figure 3Figure 4Figure 5
DisplayLink display connectivity has been limited on macOS releases 10.13.4, 10.13.5 and 10.13.6. This is solved from macOS 10.14 Mojave onwards and v5.x DisplayLink software. DisplayLink recommends updating 10.14 to restore multiple extended display support.
From this page you can download a driver for your DisplayLink enabled USB graphics device that is incorporated in your dock, adapter or monitor. This software provides support for the DisplayLink enabled video outputs. The audio and Ethernet support is provided by native macOS drivers from OS version 10.11.
DisplayLink (formerly Newnham Research) is a leading semiconductor and software technology company that specializes in developing the DisplayLink USB graphics technology. This cutting-edge technology enables computers and displays to connect seamlessly using USB, Ethernet, and WiFi, and also allows for multiple displays to be connected to a single computer. DisplayLink's primary customers include notebook OEMs, LCD monitor manufacturers, and PC accessory vendors, and their technology is compatible with a wide range of operating systems including Microsoft Windows, macOS, Android, ChromeOS, and Linux.[1]
DisplayLink launched its first semiconductor product family, the DL-120 and DL-160 USB 2.0 graphics devices, in January 2007,[8] signalling an important change in the company's business plan from FPGA-based systems to semiconductors. The DL-120 and DL-160 allow up to six additional monitors to be added to a PC through USB 2.0.
In May 2009, DisplayLink launched its second semiconductor product family, the DL-125, DL-165, and DL-195 USB 2.0 graphics devices. This DL-1x5 family brings improved performance, an increase in maximum resolution to 2048x1152, and the integration of a DVI transmitter and video DAC. The first products to ship with the new DL-1x5 chips were the Samsung Lapfit LD190G and LD220G monitors.[9]
On November 17, 2009, DisplayLink announced their first Thin Client product based on their USB 2.0 virtual graphics technology, designed for Microsoft Windows MultiPoint Server.[10] Thin client manufacturer HP was the first to announce a product based on DisplayLink USB Graphics technology with the launch of the t100 Thin Client.[11]
At the Consumer Electronics Show (CES) in 2012, DisplayLink announced several products incorporating video and graphics over a USB 3.0 "SuperSpeed USB" connection, showing substantial improvements in performance, resolution support, and video quality.[12]
The DisplayLink network graphics technology is composed of Virtual Graphics Card (VGC) software that is installed on a PC and a Hardware Rendering Engine (HRE) embedded or connected to a display device. The DisplayLink VGC software is based on a proprietary adaptive graphics technology. The VGC software runs on a Windows, macOS, or Linux host PC and takes information from the graphics adapter and compresses the changes to the display from the last update and sends it over any standard network including USB, Wireless USB, Ethernet, and Wi-Fi. After receiving the data, the HRE then transforms it back into pixels to be displayed on the monitor. While the basic network graphics technology can be used on a variety of network interfaces (Ethernet, and Wi-Fi), DisplayLink has to date only designed products around USB 2.0, USB 3.0, and Wireless USB connectivity.[17]
DisplayLink drivers are available for OS X 10.8 and later but newer DisplayLink chipsets require newer versions of the driver, which in turn require more recent macOS versions.[30]DisplayLink confirmed that macOS version 10.13.4 through 10.13.6 broke compatibility with their driver. DisplayLink is supported on macOS 10.14.macOS 10.13.4 introduced support for external graphics processors also known as eGPUs.[31]
2. Updates to the screen are automatically detected and compressed using the DisplayLink compression technology (DL2+ or DL3). This adaptive compression technology automatically balances the compression methods based on the content, available CPU power, and USB bandwidth, providing the best possible USB graphics experience at any given moment.
The next thing to check are security settings in MacOS. By default MacOS will attempt to block software from 3rd party developers unless specifically allowed, normally the system will prompt to allow the blocked software however we have had many reports of the drivers being silently blocked.
A lot of users have reported DisplayLink failure soon after a Mac OS 10.15 update. Since DisplayLink can be vital to the proper connection of your screens, this problem can be a serious one. In recent times most Mac users have come to rely on DisplayLink to connect multiple displays and computers using USB, Wi-Fi and Ethernet. If something goes wrong with one of these connections or the software itself, all connected screens can turn black or become unresponsive.
DisplayLink has two components - a software driver installed on your computer and a hardware chip in the dock or adapter. The software driver presents itself as one or more displays to the computer. The computer sends pixel data to the software driver, which then compresses the data and sends it over USB. The DisplayLink chip decompresses the data and sends the display signal to the (real) display.

Another google search doesn't reveal anything helpful. All links relate to simply silencing the messages, and they have to do with those USB DisplayLink monitors that obviously don't have QE/CI drivers written for them. However, I am using a supported graphics card with a loaded kext, and I wanted to see if it was possible to binary patch WindowServer or something like that to manually enable support for my device. Thank you. 2ff7e9595c
