Default DisplayLink Software - High CPU on MBA

Hi,

Over the last two days the CPU on my MacBook Air has ramped up and it appears to be the DisplayLinkManager process that is the cause. I am seeing on average 90% CPU being taken up throughout my working day when it is being used to run two monitors.

Reading other threads, this was apparently fixed in version 2.5, I am currently running 2.6 on Sierra 10.12.1.

Does anyone have any advice? I'll try and re-install at some point when I get a chance to see if that has any effect.

I think this is another known issue. We have a fix coming up, we are testing it now.

Will be in the next version, most likely a beta.

Regards

Default Similar problem with MBA early 2014

I've similar problem since I purchased the DL adapter.

I've MBA early 2014 i7/1.7GHz on 10.12.2 + DELL D3100 w/ DL driver 3.0 b2 (just one monitor connected on the HDMI with full HD resolution)

I tried different combinations:
DL 2.2 + OSX 10.11.4,5,6
DL 2.6 + OSX 10.11.6
DL 3.0b2 + OS 10.11.6, 10.12.2

The DisplayLinkManager goes crazy every second day and uses >100-110% of the CPU, event with no windows or application running on that desktop.

Little did the DL driver updates or the Mac OS software updates.

Other colleagues experienced the same problem with slightly different configurations.

Is there gonna be any reasonable solution in the near future?

Best,
V.

Default Still seeing some high CPU usage

I have a goFanco USB 3.0 to HDMI adapter that uses a DIsplayLink DL-3500 chipset. I have tried various drivers since last summer, including the latest driver 3.0 beta 2 23 Dec 2016 on Mac OS X 10.10 Yosemite. With the previous 2 driver versions, I was seeing VERY high CPU usage on a 2012 MBP 13" 2.93GHz i7 (averaging around 22%, spiking to 99%). This last update helped reduce the CPU usage, but I still see it pop up on my CPU monitor program throughout the day (iStats Menu). I am keenly aware of hoggy processes since going from a quad core iMac to a dual core MBP for portability, so i hope this issue can be fully addressed, soon!

Default

Just register to report the high CPU usage issue still not solved:
  • OS: MacOS High Sierra 10.13.2
  • DisplayLink: v4.3 (latest)
  • Device: Targus USB3 DV1K-2K compact Dock (DOCK120EUZ)
  • CPU% : 100%+ (only HDMI*1 in use)
  • Hardware: Intel i7 2.4Ghz + 8GB + SSD | Intel HD4000
  • Active /resident processes: DisplayLinkManager + DisplayLinkUserAgent

I noticed the program is listed by MacOS as Unix program, i.e.
Does it mean not complied/optimized for MacOS?
