I'm on 10.4.4 with 5.1.1 on 13 Inch 2015 Macbook Air. It doesn't work for me, it mirrors but doesn't extend. As mentioned earlier you can move your cursor over but everything else is still mirrored.

I'd be interested to know if the latest DisplayLink for Mac on 10.4.4 works for anyone at all?

If not, this should be top priority to get fixed. Not being able to have a second monitor is standing in the way of my productivity and I imagine countless businesses rely on this.

I just tried the 5.0.1 driver with 10.14.4 and it works for me - the display is successfully extended over two monitors.

@wrbluepearl - You mentioned that you tried 5.0.1 with no success? Try running the uninstaller for 5.1(.1) first, reboot, reinstall 5.0.1, then reboot?

I'm going to stick with 5.0.1 for now, I'm not going to install anything else until it's confirmed fixed.

Tried 5.0.1-- not working
 

I tried Driver 5.0.1 by uninstalling 5.1.1 first and then installing the new one (with reboots) but the exact same problem presists

That was the procedure I'd tried (sorry, been away from work for two weeks); have not tried the 5.1.1 driver yet (installing that now). It was more restarts in a day than I normally do in six months! :)

Same weird behavior with 5.1.1 driver
 

So, I've now tried the 5.1.1 driver, and no luck - same weird behavior. I've attached the dump from the support tool.

No luck
 

External monitor detects the input source but is receiving no signal.

2012 Macbook Pro
macOS Mojave v. 10.14.4
DisplayLink driver 5.1.1

Frustrating
 

I've tried all the drivers 5.1.40 and 5.0.1 with no luck. Is there any fix for this available?

no singal
 

2016 Macbook Pro
macOS Mojave v. 10.14.4
DisplayLink driver 5.1.1

any solution?

Is there any update on the state of this issue?

I have a Mid 2015 10.14.4 that i use for work with 5.0 drivers installed and had no issues with my DisplayLink dock at home.
But I was having issues with getting external monitors to work on a newly acquired Mid 2015 Pro, 10.14.4. 5.1 drivers didn't work, uninstalled 5.1, tried installing 5.0.1 still no luck.

I then plugged in an HDMI cable from Mac to a monitor and that worked (just the one). I went into Arrangement tab to see if other monitors (from DisplayLink) showed up. Still nothing. Then i unplugged the USB 3.0 (to DisplayLink hub, HDMI still plugged in) and plugged back in and then all of a sudden the Arrangement tab showed 3 external monitors (Hdmi, 2 hooked up to DisplayLink). Unplugging HDMI got me down to just the 2 externals. Unplugging and plugging in the USB cable will bring back the monitors like i'd expect.

I am not sure what plugging in the HDMI did, but seemed to kick something into gear and i don't plan on updating to 5.1.
