I just purchased two S2817Q monitors to go with my new Dell XPS. I hooked up one through DP (display port) to graphics card and one through DP to motherboard. The picture is great, but when I click from one monitor to the other, one monitor goes black for a split second then comes back. I also notice the format of the monitor changes back and forth between Standard and Multimedia mode which must be the flicker. When I hook both monitors up by HDMI (one to graphics card, one to motherboard) both work fine but the picture quality is just a bit less.
* What specific Dell XPS model?
* What operating system?
* What specific GPU/video card?
* Did you install the DDM (Dell Displays Manager) software? If yes, uninstall it, reboot the computer and retest
* On each S2817Q, press the Menu button. What is the left Resolution and right Maximum?
*Tower Special Edition (Is that close enough?)
*Nvidia GeForce GTX 1060 w/ 6GB GDDR5 Graph memory
*Tried uninstalling display manager software already
*Both monitors 3840 X 2160 res
You should be connecting both S2817Q to the added Nvidia GeForce GTX 1060 video card. One using Nvidia GPU while the other using the onboard Intel GPU might be your issue.
