Setup:
2x U2715H Monitors
Microsoft SurfaceBook (i7 w/ discrete Graphics card)
Windows 10 x64
Microsoft Surface docking station
Configuration:
Config A (daisy chain):
DisplayPort 1.2 was enabled on both monitors. mDP OUT from docking station to DP IN on first monitor. DP OUT from first monitor to mDP IN on second monitor. This configuration worked and I was able to get the monitors to extend the desktop display, but experienced disconnection issues, so I tried without daisy chaining (MST).
Config B (straight run):
Disabled DisplayPort 1.2 on both monitors. Both cables mDP OUT from docking station and ran individually to each monitor's DP IN. It took some time to get Windows to recognize the monitors and get the desktop to be extended on both displays like in Config A but I eventually got it working. Even with the MST configuration out of the equation, I still experienced the disconnection issues.
The Disconnection Issue:
The monitors become "disconnected" in that the OS no longer recognizes/sees them. Sometimes they recover on their own but other times I have to go into the OS display settings to "detect" them. If that doesn't work, I either have to physically disconnect/reconnect the docking cable and/or restart the OS. Some days this happens often, other days it only seldom happens.
Windows is up-to-date with the latest updates (and I continually check daily to ensure the latest updates are applied). Since Windows 10 and the SurfaceBook have had some rocky starts with stability, I started with troubleshooting the OS first.
I'm bringing this issue up here because a co-worker has the same laptop but with different monitors and they are not experiencing this issue.
I've tried installing this driver:
but I get no change in behavior.
Is there anything else I can try or something that I may have overlooked in configuring Windows 10 to extend its display on to these monitors?
