I tried to connect my Thinbook to a projector using the mini HDMI port on the laptop. However, what the projector showed was totally different than what was there on my screen. The projector showed some colourful wallpaper but no applications. Can some one help me set up the HDMI port correctly to work with video projector or TV with HDMI port.
One curious thing I noticed was that when I went to shut my laptop, the projector did show the icons that appeared on the screen for Hibernate, Reboot, Shutdown, etc. but the background remained the same colourful wall paper.
If you don't have Micro HDMI, see if your laptop has a DisplayPort, which can handle the same digital video and audio signals as HDMI. You can buy a DisplayPort/HDMI adapter or cable cheaply and easily. mechanic
If you do not change the input source to HDMI port. Then you will not receive the signal via HDMI cable and your computer will not detect it. This is why the HDMI input has no signal on your screen.
