Windows 7: 4k monitor issue

02 Feb 2016   #1

4k monitor issue

we have a laptop and it has two external screens hooked up to it (so we are using the laptop screen, and two secondary screens). one of the screens is a 4k tv. we have it hooked up to the pc using an hdmi cable (hdmi in tv, then hdmi in the laptop). the other screen is connected display port to mini display port. we are able to set the resolution correctly on the 4k tv, and see the desktop correctly, however if we drag an application over to the screen (like internet explorer), then maximize the app, the tv goes blank and says no signal. any ideas? the other screen works fine. and we had another monitor in place of the 4k before that worked fine (though it wasn't a 4k tv, just a regular monitor)
