I expect that fjant has left the building by now, but in case anyone else has this annoying problem the steps to try and fix it are as follows: 1) Make sure the HDMI cables aren't faulty (which you seem to have done already). 2) Switch everything off and back on again - this has been known to clear problems of many varieties, in cases where electronics have gone into hysteresis and fail to respond. 3) Make sure that the display drivers are up to date. If this problem should happen on a PC (which it does, as was the case with my own recently), this is done via the Device Management console. You can reach this via Control Panel, or by typing devmgmt.msc at the command line. 4) If the above step does not work then try manually downloading updated drivers from the website of the video card's manufacturer. 5) If none of the above works then it could be that the HDMI port has a problem, which for most users will need to be fixed by an [http://www.northdevonitservices.co.uk|IT specialist] or by returning the equipment to the manufacturer or the shop where it was purchased. If under warranty then check the small-print for information regarding returns. I hope that some of the above helps someone with this niggling anomaly. Although HDMI is supposed to be a standardised video / audio medium, compatibility is not always guaranteed and it could be that two devices simply don't bond with other, electronically speaking. Good luck.
