There & Back Again
Hey guys, not sure if I'm on the right thread or not.

Anyone else having trouble getting USB monitors working on High Sierra? I have a 7" Liliput monitor, and an AOC monitor, both USB, both working great prior to 10.13. Even after a fresh install, updated drivers, uninstalled and reinstalled drivers, they don't work.

Am I alone in this? Can't find a lot of info online about it.
 
tested it on MacPro6,1 running macOS High Sierra 10.13.3 with a hp-branded DisplayLink USB to DVI adapter (latest drivers downloaded from the DisplayLink website. it works just fine...
 
These monitors aren't using adapters, these are USB powered and connected monitors. No DVI, HDMI to USB conversion, and they aren't working...
 
yup. but since you mentioned the DisplayLink drivers we can assume that both (my adapter & your monitors) use the same chipset. the displays with the integrated DisplayLink chipset will of course draw a lot more power.
 
I'm just struggling to troubleshoot it. Neither of them work on my computer now since High Sierra. Super handy and needed for my workflow...

I haven't had any probs till yesterday when I upgraded to 10.13.4 and my display connected via a Displaylink usb to DVI displays a lime green screen. The mouse pointer displays fine when I drag it over there and if I take a screen shot cmd+shift+4 method - I get a screen shot of the screen how it should look so something is creating the green screen as I've even been able to drag app windows off that display by guessing where. the windows are.

I've tried uninstalling the driver, reinstalling the driver. Force quitting displaylink user agent and displaylink manager in activity monitor (a fix from earlier OSX - maybe yosemite). If I turn on mirroring, it appears to crash the system or log me out. I've also tried connecting the displaylink preboot, afterboot, while running, and all of the other basics. When reinstalling I don't have that security issue where I have to approve the extension. I wonder why that is. Maybe because it's been trusted before and my uninstalls aren't complete?
Anyone have any ideas????

Hi mikeboss, do you know if the USB display link adaptor require a working graphic card to display anything in macOS?

I am thinking if it can be the emergency tool to let my display work when Nvidia web driver is not yet installed (my Mac Pro only has a single Pascal GPU installed).

I am OK to deal with unaccelerated screen, but just want something to display like the EFI driver does. If anything super critical, I can always go back to my 7950 Mac Edition card. I am looking for a simple solution to avoid card changing in less critical situation.

hm... no idea. what I know for sure: cMP starts without any graphics card installed at all. so yeah, it might be possible to start with a DisplayLink adapter alone. I also know that this setup (no GFX except a DisplayLink adapter) works with Windows 10 (1703 and newer). I don't own any classic Mac Pros anymore. so, unfortunately, I'm unable to test this with macOS.

This is already some very good useful info to me. Thanks you very much!
 
AOC monitor with the latest DisplayLink drivers work fine on 10.13.3. Haven't tried on 10.13.4 beta
 
10.13.3 is really impressive compared to any other build using the DL drivers. That being said, the driver is broken by 10.13.4 beta builds so I would avoid completely. See the DL forums for more info.
 
The DL driver completely dorked my rMBP running 10.13.4 beta. Couldn't use my mac except in safe mode.

Wow thanks for the heads up on this.

What on earth is going on with OSX these days...

Trying to use the AOC e1649fwu on my MacBook Retina using High Sierra. It worked previously with an older MacBook Pro. The driver dmg I found was "DisplayLink_Mac_2.2.dmg." No dice! Restart, and the display doesn't show up in "displays" in "System Preferences." You seem to have resolved the issue, so your input would be appreciated.

I had to uninstall the DisplayLink driver on the 10.13.4 betas because my MBP would not boot except in safe mode. I am on 10.13.5 beta 4 and will try again.
