I have had five UGA-2K-A adapters plugged into my work PC docking station for the last several years, and they’ve been GREAT.
That Dell Latitude E5440 was getting fluky, and due for replacement, so I now have a Dell Latitude E7470. Everything else has remained the same - still Windows 7 Enterprise, still same docking station with same adapters and monitors. The only difference I know of is that the old PC used DisplayLink 7.7 drivers, a version not supported on the new PC; that’s on 8.2.
The behavior I’m seeing is that windows on all of the displaylink monitors are failing to repaint. Sometimes I only get the window borders. Frequently, a window popping up over another is just a blank box. Almost constantly the window below is “painted” with what was on top of it, and doesn’t update back to itself when the window on top is dragged away. Instant message conversations don’t reflect current typing. Scrolling a window doesn’t do anything. But ALL of these conditions resolve (temporarily) if I move the window around a bit.
Please help - the only way I can function at work is with this bountiful screen real-estate, and now I feel as though I’m working on a postage stamp of two mere 1920x1080 monitors.
