Just installed the Plugable 5900 with two external monitors. I immediately noticed small colored rectangles blinking on the screen. It occurs somewhat randomly, but frequently show up when displayed rich, saturated colors. I’ve made a video of this here: https://youtu.be/anUtrxS6Q9A (quality isn’t that great, but go second 55 where I get the camera closer and you can see the rectangular artifacts easier).
The effect is similar to what is described in this issue http://support.plugable.com/plugable/…], but I am not pressing on the Plugable device. I have two laptops, and the issue occurs with both. Disconnecting a monitor seems to help somewhat. Using different video cables had no effect, but replacing the Plugable-supplied 3.0 cable with a different one *significantly* reduced the artifacts. Given this, does it sound like a cable issue, or perhaps something else? If it is the cable, what can I do to ensure the artifacts stay away?
Thank you - Rich
