Hi,
I have a Dell U2413, connected through mDP to my Asus STRIX GTX 750Ti OC. As soon as I switch from DisplayPort 1.1a to DisplayPort 1.2 mode, DDM doesn't recognize the monitor anymore, showing a red cross in the icon in the task tray and, when hovering over it, showing "Please connect a supported DELL monitor". As soon as I switch back to 1.1a again (after re-powering the monitor) DDM recognizes it again. While researching what the cause could be, I found this post: en.community.dell.com/support-forums/peripherals/f/3529/t/19501339
which describes the same symptoms. I didn't want to post in that thread as the date is from 2013, had no resolution, and I wanted to post a new descriptive title.
My config:
- Asus STRIX GTX 750Ti OC, Driver v347.52;
- Dell U2413
- Dell Display Manager v1.21.0.1500
- Windows 8.1 Pro
Thanks in advance.
