I bought this unit after trying one of the cheap USB powered units. This is much more reliable as it doesn't affect the display of the screen. Less expensive made my laptop think one of the screens was off when I switched to another computer. This resulted in undesirable behavior such as B. Reorganizing the layout of all my windows on the desktop. Even the cheaper switch was often blocked. This switch has none of these problems. The change takes a few seconds, and then everything is fine. I've been using it for a few days now and I'm very satisfied.
