M1 Macbook - Display Link resetting on Ventura

EddL101 · 03-01-2023, 12:06 PM

2020 M1 13 inch Mac book
Ventura 13.2.1

Kensington SD4780p

2 x IIyama Prolie X2377HDS on HDMI

------------------

Following an update to the latest OS (I was on Big Sur then briefly Montery and now Ventura) I have found that ecery 30secs - 1 minute the Hub is resetting and loosing both monitors/connection. It will then reconnect again and work.

I've changed to 50hz from 60hz and disabled HiDPI mode but still no joy.

I've rest the SMC in the usual turn off wait for 30 secs and turn on fashion for the new M1 chips.

I've also got Kensington Dockworks installed and running in case that helps.

I'm on the latest build of display link on a fresh OSX install (totally wiped prior to Osx update).

I can get a single external monitor to work direct from one USBC/Thunderbolt 4 via a dongle and HDMI cable so I know it's not that.

I've also tested all the cables and the dock on a PC which all works fine so I'm 100% it's a conflict between either the hub or dockworks. If I leave the hub plugged in without the monitors then it seems to be stable so at this point I can only assume it's a display link software issue within Ventura.

Can anyone help as this fault is seriously impacting my workflow?

Thanks in advance
