Intermittent Display on MAC

SajoR · 09-09-2020, 05:24 PM

Hello, I´ve installed the latest driver to use my USB Display on MAC OS Catalina, unfortunately it works only for a couple of seconds and then it becomes intermittent. I´ve checked the logs and I found this

LOG
Sep 9 12:19:31 MacBook-Air xpcproxy[11310]: libcoreservices: _dirhelper_userdir: 557: bootstrap_look_up returned (ipc/send) invalid destination port

Sep 9 12:21:18 MacBook-Air com.apple.xpc.launchd[1] (com.apple.preference.displays.MirrorDisplays): Service only ran for 3 seconds. Pushing respawn out by 7 seconds.

11310 ?? 0:00.02 /System/Library/DriverExtensions/AppleUserHIDDrivers.dext/AppleUserHIDDrivers com.apple.driverkit.AppleUserUSBHostHIDDevice0 0x10000f33d

System recognizes the monitor as it supposes to do:

e1649Fwu:

Product ID: 0x4107
Vendor ID: 0x17e9 (DisplayLink (UK) Ltd.)
Version: 1.25
Serial Number: EXUD2HA013735
Speed: Up to 480 Mb/s
Manufacturer: DisplayLink
Location ID: 0x14100000 / 30
Current Available (mA): 500
Current Required (mA): 500
Extra Operating Current (mA): 0

Even when I got the logs, monitor doesnt turn off immediately , it happens some seconds later and it is randomly, last time I worked for 1 hour and the display worked fine.

Any idea about what could be happening? I´ve used different USB cables and still happens the same.

Any suggestion? it seems like a bad cable or plug, but i´ve tested both of them with good results, if I connect it to a Windows machine it works good. any idea?
