Purchased a new Dell XPS 13 at the very end of December 2016 (so BIOS, etc. should be current?) and just received my Thunderbolt 3 dual HDMI Adapter from you folks yesterday.
When I first got it going yesterday, I had no problems - monitors stayed on with stable display for as long as I needed them, all day long.
I installed regularly scheduled updates (running Windows 10) this morning, and suddenly my screens are randomly losing signal, blanking out, then regaining it. That’s literally the only change I made.
Also, occasionally getting a “stutter” in the screens as well where the display glitches for a split second, then goes back to normal… seems to precede total loss of display.
