Rechtstreeks van de box naar de tv werkt goed. De reciever heeft inderdaad twee ingangen die alle bij het zelfde doen. Ik heb ook twee kabels gebruikt om dat uit te sluiten. Ik vondt het volgende op de website van Harman:
My cable set-top box works fine when I use an HDMI™ link directly to my TV (video display), but when I connect it through my AVR it doesn't work, and sometimes I'll get a "NO SIGNAL" error message on my TV. What could be the problem?
Answer: This issue is most often caused by a software problem in the cable box that prevents it from working with "HDMI repeater" devices, such as an AVR. Please contact the customer service department of your cable operator and describe the problem to them. In many cases they will be able to send a software upgrade directly to your cable box to fix this compatibility issue.
Zou UPC zo iets weten en of kunnen?
