    Daisy-chaining mirrors instead of extending displays


    Runnig MSI GT80 Titan SLI, with dual Nvidia 980m. Two monitors are Dell U3014, both. I run this config: CPU -> mini-DP to DP on primary U3014 - DP-out to DP-in (Secondary Dell U3014) the monitors are mirrored. Windows sees daisy-chained monitors as a single U3014. I have successfully daisy-chained two U2713HM monitors with this machine so know it can be done. I set the MST to "on". However Dell U3014 lacks the MST option. So I set both to Display Port 1.2 and there aren't any options in the on-screen menu. Nvidia config program isn't of any help either, it too like Windows sees only one U3014 monitor instead of two. I've done driver upgrades, rebooting, powering off, removing power cables, etc. to no avail. I am running the latest-greatest Win 10 prior to this newest upgrade that's not forced yet. - - - Updated - - - solved it.. it's the confusing Dell U3014 OSD menu While it does not explicitly mention MST, turning on DP 1.2 apparently also turns on MST. The menus are downright confusing. The older Dell U2713HM specifically stated MST.

  2. DisplayPort Daisy Chain on Dell Monitor not working

    We have a problem where a user has 4 monitors hooked up to their Windows 10 system with an RTX 2070 for graphics. They wanted to reserve the HDMI slot on the card, so I suggested running their 24" Dell monitors by daisy chaining the last two monitors. We enabled DisplayPort 1.2 in the Dell settings (FYI - you need to have a valid video signal to get to the menu to turn this on) and double checked that MST was enabled for the graphics card. After plugging in the daisy chained monitor, the monitor would flicker an image of the desktop for a second and then go black.

    Windows 10 registered that the monitor was attached and daisy chained but we couldn't get an image to display. Looking around the web and I found a lot of articles saying Dell monitors are terrible for daisy chaining but beyond not enabling DP 1.2 and MST, nothing else was a solution to our problem. Since there is an image that flickers when you first hook it up, it seems like it is just a driver or display issue. Any thoughts?

  4. Daisy-chaining mirrors instead of extending displays

    Using a Display Dock HD500 to extend across two Displayport displays

    Does anyone know or got working using a Lumia 950XL with a Display Dock and two Displays daisy chained using their displayports in "extended" display mode. I have it working just fine as "duplicated" but there does not seem to be "extended" capability.
