Kim, would you mind letting us know if your setup is still working after completing the Insider update? We’ve been at this same issue for nearly two weeks, having tried multiple docks, a half dozen cables, and numerous calls with support. Stumbled on this
thread tonight as we were readying our replacement SP7 request...your post has given us hope!
Hi, I have been running that last Insider update for the last 36 hours and haven't had a single graphics issue.
I too was very close to returning the SP7 as was convinced it was a hardware or soldering issue. It was just a luxury that we had bought 24 of these, so I could keep unpacking them and trying the next one. That's when became certain it was software updates
causing it, then I had the tip off new Firmware's were just put on Insider.
My successful testing has been solely with the SP7, Surface Dock and 1x UHD external monitor. I haven't gotten around to testing the Satechi USB-C to HDMI Dock yet or the USBC-HDMI cable, but I am confident they will all be working fine now as there hasn't
been any spurious event log entries like there was before.
My only issue, Windows 2004 has had two sad face crashes but seems to be something else. This was while the system was asleep.
I'm pleased with this outcome, as I was prepared to be boxing all 24 back up and returning them - and I wasn't about to take any form of "you need Surface Dock 2" as a way out. (unless they paid for them...) Now I just have to figure out the implications
for the other 23 Surfaces. It would be nice for Microsoft to tell us whether it is these new Firmware's alone that fix this display problem and if they can, release those independently of Windows 2004, so we can get on and deploy the firmware's across our
fleet of brand new SP7s while we wait for the official 2004 release.
What an experience!!
