I connected the adapter properly, but get no picture. What's wrong?

You can check several things to find out the details: - Check that the HDMI output is enabled on the PC (e.g. try connecting your PC directly to a TV with an HDMI cable). - In some cases PCs do not provide enough power on the HDMI port. In this case you can connect external power to the adapter's Micro USB connector. You need a Micro USB cable like item no. 440-33 and a USB power supply like item no. 440-56 (EU) or 440-77 (UK). - Try setting the screen resolution on your PC to the lowest possible. If this works you can then try higher resolutions.
