Nicolas Hanson November 29, 2017 Share November 29, 2017 In one of our suites we got two computer screens connected to a graphic card through display ports. The screens are set up to regular HD (1920x1080) and that worked fine until I unplugged one of the screens and connected a high resolution screen to one of the ports. That probably caused the Windows display resolution to increase automatically, so when I plugged in the original screen again both the screens went black. They are working properly until I enter Windows. I tried to enter safe mode, but it doesn't let me change the display resolution as it 'disconnects' the graphic card. Any idea how to deal with this?

Bruno Mansi November 30, 2017 Share November 30, 2017 Try going back to one 1920x1080 display, so that Windows will set the resolution to match. You can then check the settings to make sure they're correct before connecting the second display. 1 1 Link to comment Share on other sites More sharing options...
