I have a Dell Inspiration 7391 with UHD graphics card. Native display 4k. I use the laptop as my desktop but use an external Scepter monitor with a native display of 1920 x 1080. I would like to use the Dell graphics card for my monitor that is able to display 4k as long as my laptop lid is open. Any idea how I can do this so I can keep my laptop lid closed?
