Why my Dell LED in2030 display vibrating? Display iFixit
1. If the picture on the screen is vibrating, or seems like it's shimmering etc, it could be the refresh rate is set improperly on the monitor or the resolution is too high. 2. Before we go there, however, the quickest first thing I would do is just press the menu button on the monitor itself and access the monitors menu to do a factory reset.
