Display Port Lag
Any thoughts about Display Port Lag with the DL drivers?
Using the Totu TT-DC0002A USB-C dock with a new MacBook Pro 16 and the DP screens lag terribly. OS X 11.1 & DL drivers as of 1/2/21. 1x HDMI Landscape Mode 2x DP Portrait Mode Screens are set up: Portrait (DP) | Landscape (HDMI) | Portrait modes (DP) -- they look like an H - a layout I've been using for years. The HDMI port is fine. When moving windows to the DP screens, it's choppy and the mouse gets jumpy. None of that has helped as anything Display Port is laggy. <EDIT!> Just saw something ... that "rotation" isn't supported. https://support.displaylink.com/know...ntroduction-in Both of my DP screens are rotated to Portrait mode! Rotation is not supported on macOS Catalina 10.15, Flipping my screen to Landscape mode resolved the lagginess. I'm on 11.1. Is rotation going to be supported at some point? That'd be a life saver. Thoughts? Thanks! Last edited by toloughlin; 01-09-2021 at 03:43 AM. Reason: found a resolution, but not a fix. |

You have non M1 mac that natively supports multiple external Displays over its 4 Thunderbolt3/USB-C connections.
I would use USB-C to Display port adapter or a Native Thunderbolt dock. I have and really like the Targus 180 and a Caldigit mini thunderbolt 3 dock. I have both an M1 MacBook Air 16/1TB and MacBook Pro 15 Note that Displaylink chipset /drivers for most DisplayLink powered docks rely on USB 3.2 Gen1 at 5Gbs versus Thunderbolt 3/4 native 40GBs. I have no lag with video on my two monitors on either dock but my needs may be more modest then yours. I suspect the issue your having is with the TT dock you bought being sketchy. Thunderbolt docks and USB-C to display port adapters have no issue with rotation and require no drivers. Good Luck. Last edited by anthlover; 01-10-2021 at 01:45 AM. |
