You did NOT reach at me! I have a ticket already opened. I have to deal 63 7090 with DP issue.  Update-Update = After completing troubleshooting, a DELL-Cares agent setup a part replacements.    
We have purchased over 40 Dell OptiPlex 7090 (tower) PCs. The top display port is not working on all of them.  We've contacted the Dell but no news from them. We use two monitors per PC therefore we need a permanent fix for the top display port.  1- We have tried different version of windows 10 and windows 11, same issue 2- Second monitor shows as disconnected under the display setting. When enable, you can see the second monitor, however when you reboot, the top display port gets disconnected again.  3- Install intel video drivers, enabled the second monitor from the software, same situation happens, when reboot the settings are gone.    Can dell acknowledge this issue and provide a fix? I really don't want to replace motherboard on 40+ PCs.  Any help will be appreciated.  Emmett
