Paultx Posted November 9, 2010 Share Posted November 9, 2010 (edited) Windows 7 provides an easy way to access and switch between external displays, so you can use more than one monitor or a projector for presentations. The Windows key + P combination opens this handy toolbar: Computer only is the default option–and the name says it all. Duplicate clones your screen to a connected secondary display, monitor or projector. Extend expands the desktop so you can make room for extra windows. Projector only turns off your laptop's LCD and turns the projector into your monitor. Source: PC World Edited June 24, 2011 by Paultx Link to post Share on other sites
TYE Posted January 4, 2020 Share Posted January 4, 2020 Hi- th[s I was trying to figure out why I was getting "no signal" when I connected my laptop to my TV and I thing I set the TV to primary mistakenly in the process. Now I'm getting a black screen when I connect the HDMI cable to my laptop on my laptop. When I unhook the HDMI from my laptop I get my screen back. Does anyone know how I can reverse this? Thanks!

Tx Redneck Posted January 4, 2020 Share Posted January 4, 2020 Hello @TYEand You probably have a combination F key and display output in the top row of keys on the keyboard that changes the different output modes. Tx Link to post Share on other sites
