Recently I’ve been presenting much more often and have run into a problem during my presentations. It has to do with my Lenovo W541 connecting to projectors. I would connect and my main display was fine, but when I wanted to switch to the demos I was only able to extend the screen and not duplicate. This was a nightmare for my demos since I would have to turn and look at the screen instead of the audience. Obviously, this really distracted from the presentations and was noted in some of the feedback I received.
At first, I thought I had resolved this by switching resolutions. That seemed to work somewhat but made the screen unusable during the demos. 800*600 just doesn’t work very well for anything.
I did a little research and found out that the NVIDIA display card does not switch over by default. It must be updated in the BIOS and not through the NVIDIA Desktop Manager.
In the BIOS, go to Display >> Discrete GFX Perf Mode >> High Performance and restart.
There might be some performance hit after the display card is switched. I haven’t noticed any difference in performance or battery.
