Displaylink unreliable in windows 10, Intel 4970, ga-h81m-hd3 motherboard

Thank you so much for the reply! My apologies for my impatience.

Here is what you have asked for:
1. Only once did I hear the disconnect sound (only on the e1649Fwu device)--most the time it simply stops with no fanfare (if I'm not immediately using the screen, the biggest giveaway is that the desktop clock has stopped in the lower right corner).
2. Yes, the same problem occurs if it is only the e2251 connected.
3/4. the plug is secured and I have tried a different cable. The same problem occurs.

So alas... no difference. Randomly, the display will freeze or (more frequently now), I will run a game, and when I am returned to the desktop upon exiting, the monitor is still recognized and displays (the last thing that it was displaying before I launched the game) but is unresponsive. If I unplug the monitor and plug it back in, it still does not come back to life until a full restart.
