In its standard rotation it works perfectly, but when I turn it 90 it starts to have a lot of lag. It does not make sense because the resolution is the same.

The installed version is DisplayLink 75598 this is the last?

What is the problem? Thank you.

I've been having a similar issue with USB-C 2017/2018 Macbook Pro's running latest DL drivers on Mojave 10.14.5 connected to a Humanscale M/Connect 2 dock. (I have support tool logs if someone from DL would like to take a look)

In testing using x2 1080p Dell monitors 1 in landscape and the other in portrait. The portrait screen has a very noticeable amount of lag.

I've tried a few different combinations.

- Disconnecting the landscape screen from the dock did not improve the lag.

- Lowering the resolution of the portrait screen did improve the lag slightly.

- Using https://www.testufo.com/refreshrate the portrait screen is running at 60hz (if this is an accurate tool) so maybe this rules out the refresh rate being changed?

I've yet to test on Windows device but something tells me this only affects Mac OS.

I'm unsure if this is a displaylink issue or dock specific, I have used portrait mode on a Dell DA6000 with the same Macbook, using DL drivers and a similar monitor setup in the past and had no issues with lag while one screen is in portrait mode.

There seems to be a few threads reporting similar issues. https://www.displaylink.org/forum/sh...ad.php?t=66434 https://support.displaylink.com/foru...ns-on-mac-os-x
