I have the same problem and the support people advised me that the cable could be faulty. However, I have found that the problem is in the instrument itself and not the cable or the TV. The instrument does not register the type of connection if it is already plugged into the TV. If you unplug the cable and plug it in again, it registers the resolution of the TV and works fine. So, this is the best way to work around it. It is a bug in the system and WD will have to fix it.
