How to get displaylink usb video adapters to work in MacOS High Sierra (10.13.4) April 2018 release

Transcript:Okay, if you’re watching this video, it’s because you have done exactly what it says not to do on the display link.com website and by extension also the ProPresenter website from Renewed Vision, which is you’ve upgraded from a MacOs 10.13.3 to 10.13.4 which normally these dot releases don’t really do a whole lot. There’s security stuff, etc. In this case, it made it so that the displaylink USB adapters do not work.

So let me guide you through the steps on how to fix this. And I’m doing this with you. So we’re going to see if this works. I have already downloaded this driver, which was from May, 16th as I’m recording this. It’s May 20th, so it’s been a couple of days a Beta 4 that’s important. Downloaded it.

First I followed these directions up here and I uninstalled this driver and then I downloaded the new driver here, installed it, restarted it. And now we’re going to go through these directions which you can get to by clicking this “Please see our article link.” So I’m going to click that and this is where it says, Hey, an installed the driver reboot and sell the new driver. Restart. Login. Yeah. Yeah. Did that already.

Next, make sure. Mirroring options in the menu bar when available is checked in display preferences. So, I keep a system preferences down here and my dock, but you can also get it up here. I go to apple menu then system preferences. So I was playing with the sound earlier. So first thing we’re going to do, go to displays. Okay. This is the checkbox down here. “Show mirroring options in the menu bar when available.” Okay, so mine is checked. Cool.

Next step, we’re going to click here and then go to “security and privacy.” And then “accessibility” and look, “display user agent.” We want to check that first. It’s gonna. Ask me to authenticate that I am a user that’s allowed to do this. So if that’s locked, click it. Put in your username and password. Assuming you’re an administrator. If not, get the administrator on your computer to do it. Now, I can check that and go back here. Okay. Let’s see what the next step is. Set the dialog that opens a well to control your computer, connect your displaylink device.

Okay, I’m not seeing this up here, but I’ve got a few of those so let me see. Nope, still not there, but my display link device is already connected. I’m going to unconnect it and reconnect it and see if that affects it.

Uh, looks like something’s happening. Okay, so now I can click here. Oh look, I’ve got some different choices. Now I’m going to use “use as separate display.” When I do that. It has in fact shown up. Now you can’t see it, but let’s go into displays here and arrangement. And this is this one. This is actually my display link. I’m going to move that over because it lives to the right here and this is my main output. So I’m actually on a 2017 MacBook Pro that has two outputs, but I have this available. I’m going to do this and I’m going to gather windows and let’s click on scaled and I want that to be 720p.

So okay, that’s better. So there we go and that apparently works, and let’s just test it ProPresenter, just to make sure. I expect that it will. This is a bit of a hack, a bit of a workaround.

Um, but let’s see what happens when I do this and go into here. “Preferences”, “display”, let’s move the stage display here and let’s “enable stage display.” Oops. And you can’t see it, but it did in fact work. Um, my resolution is a little wonky, but it is fact working. So this isn’t the normal way you do. It’s a bit of a hack, a bit of a workaround, but it looks like it might just get you through, uh, your resolution might look a little wonky. I don’t know how yours is, but mine is super letter boxed. So I’m missing a lot of screen real estate, top and bottom, but this is better than nothing. So that’s the workaround to get past the problem with displaylink USB adapters in MacOs 10.13.4.
