Multiple monitors fail initialization using MST switch with Windows 10

GDyck — Wed, 18 Dec 2019 01:33:24 GMT

If I have multiple monitors connected to a MST switch, when Windows is started or awakened from a sleep state the monitors fail to initialize. If the internal monitor is enabled I find system performance is sluggish, as if a process is hung in a loop consuming CPU. When a single monitor is connected to the MST switch it is initialized properly, and I can connect additional monitors and they are initialized properly.

Topology screen shots and a dxdiag report are attached in the attached document.

Hello GDyck,

Thank you for posting on the Intel® communities.

In order to understand better this environment, could you please provide or confirm the following information?

1- Did this configuration worked before? If so, was any update, software or hardware change?

2- Please confirm how many monitors/displays in total you are trying to use with this configuration (including external monitors and built-in display):

3- Brand, models and part number of every monitor:

4- Could you please elaborate more on the configuration and how the devices are connected to one another? For instance: Laptop >> Docking >> MST splitter >> Monitors using DVI cables from MST splitter to monitors?

5- Are the cables and/or DVI video ports "DVI Single-link" or "DVI Dual-link"?

6- Please provide a Report for Intel® Graphics Drivers using the configuration you are trying to achieve. To generate the report, please follow the steps in the below link:
