I have tried all of the above without success. The monitors still periodically go blank.

I am facing this issue after upgrade to the 1.2.0. I don't have the issue before the upgrade. I have used the USB monitor and the cable for more than 5 years. (It is ASUS USB monitor). I did only have the issue, it is USB-C to USB monitor. USB C to HDMI monitor is working fine

Having the Same issues...

I'm using the Targus DOCK180EUZ and I'm running a Macbook Pro 2019 (Intel) and Displaylink Manager 1.2 with MacOS 10.15.7 and switch during the day to my Macbook Air M1 with MacOS 11.1.

There are issues on both devices, the problem occues on the Macbook Pro 2019 more often. The external monitor is abolutly unusable with this setup... works for 5 Minutes and disconnects after that for no reason. I tried every suggestion so far.

I'm very unhappy with the situation at the moment.

After installing the recently released Display Manager 1.3.0 and disconnecting and reconnecting (again) all cables, the screen blanking issue no longer occurs.

Same problem
 

Hi,
Same problem here on 2 mac.

Soft : DisplayLink Manager 1.3.0 on Big Sur 11.2.3.

Hardware : macbook pro intel 13" with a UD-ULTC4K-EU
and one macbook pro 15 2019 with a UD-ULTC4K-EU.

The problem occur each time we are playing a video on external display or during a webmeeting.

This is just a nightmare ! :mad:

Same issue on me
 

I've using

Macbook M1
OKX tripple usb-c dock
LG 4K Monitor - HDMI
Samsung 4K Monitor - Displaylink

The blank happen in LG 4K monitor not periodically but happen 1-2 times per hour.

I have been having this problem for a while also. I was using DisplayLink Manager Graphics Connectivity V1.1 which still would go blank periodically, but would recover and turn on faster. I just downloaded V1.3 today and my monitor goes blank more often and it take about 10 seconds to turn back on. I may re-download and install V1.1 since the blank monitors seem to happen less often and recover faster as well.
