Dell 1558 laptop with a broken screen up until this point has connected through an hdmi cord to the tv. For some reason now it won't connect to the tv. Iv used the function with f1 method which has not worked yet, as well as attempting to connect by using a VGA cord. Both have yet to work. I can sign into my desktop but since the screen is broken I can't see anything. Is there potentially a step by step process once on my desktop to make sure my display is set to external and more over any solution to my problem? Any help would be appreciated
